The concentration of the salt in the w crude oil (with salt) to water used is 4:1 is 0.0061.

What is crude oil?

Crude oil is a hydrocarbon mixture that exists in liquid form in natural subterranean reservoirs and stays liquid at atmospheric pressure after passing through surface separation facilities.

The salt content of "spent" wash water is 15%.

5% of crude oil is salt.

The crude oil (with salt) to water ratio utilised is 4: 1.

Crude oil fraction:

95% of crude oil = 0.95

0.95F1 = x1E1

0.95(100) = x1E1

95= x1E1

E1 = 95/X1

wash water fraction:

15% of wash water = 100% -15% = 85%

= F2 = 0.85E2

salts fraction:

0.05F1 = (1-X1)E1 + 0.15E2

0.05F1 = (1-X)95/X1 + 0.15(F2/0.85)

0.05F1 = 95/X1 - 95 + 0.15(F2/0.85) (SINCE = 95.588 = 95/X1 = 99.38)

0.05(100) = 95/X1 - 95 + 17.61(1/4F1)

5 = 95/X1 - 95 + 4.41

Fraction of salts = 1- X1 = 0.0061

The cable type that comes in two different modes, single mode and multimode is the fiber optic cable.

Fiber optic cables are made up of thin strands of glass or plastic fibers that transmit data through light waves. The two modes of fiber optic cables are single mode and multimode.

Single mode fiber optic cables have a small core, typically 9 microns, and only allow one mode of light to travel through them.

As a result, these cables are well suited for long-distance transmission because they have low attenuation and a narrow bandwidth. Single mode cables are used in telecommunications and cable TV networks

When a tennis ball is projected toward a smooth surface with speed v then rebound angle is 30° and final speed is 0.57 times the initial speed.

The rebound angle can be found using the law of reflection, which states that the angle of incidence is equal to the angle of reflection.

Since the ball is projected at an angle of 30 degrees, the angle of incidence is also 30 degrees.

Therefore, the rebound angle is also 30 degrees.

We can determine the final speed of the ball after rebounding using the coefficient of restitution and the initial speed.

The coefficient of restitution, denoted as e, is defined as the ratio of the final velocity to the initial velocity in the normal direction after a collision:

e = (v_f - v_i) / (u_i - u_f)

where u_i and u_f are the initial and final velocities in the normal direction, and

v_i and v_f are the initial and final velocities in the opposite direction.

In this case, the surface is smooth, so there is no friction or tangential forces involved.

Therefore, the velocity of the ball in the normal direction remains the same before and after the collision, and we can simplify the equation to:

e = (v_f - v_i) / v_i

Solving for the final velocity, we get:

v_f = e v_i = 0.57v

So the final speed of the ball is 0.57 times the initial speed. Note that this assumes that the ball rebounds directly back along the same path as it approached the surface.

If the rebound angle is different, then the final speed and direction would be different as well.

The given code snippet is a loop that iterates over each element in the "list" array. It compares each element to the value stored in the variable "temp". If the element is greater than "temp", it increments the counter variable "c" by 1.

Therefore, the code is counting the number of elements in the "list" array that are greater than the value of "temp".

To elaborate, the loop initializes an index variable "j" to 0 and iterates as long as "j" is less than the length of the "list" array. For each iteration, it checks if the element at index "j" in the "list" array is greater than the value of "temp". If it is, it increments the counter variable "c" by 1.

At the end of the loop, the variable "c" will hold the count of elements in the "list" array that are greater than "temp".

(b) Z* at 90% for two sided is 1.65,  CI₁ = 5.033 ,  CL₂ = 5.966

(c) 90% lower confidence bound for one sided is 5.138

(d) Now, if we compare width of two intervals in (a) and (b), we see that at higher confidence level width is greater and interval is more expanded than at the lower confidence level. So as level of significance is lower for two sided confidence interval will be more expanded.

A confidence interval in statistics is the likelihood that a population parameter will fall between a set of values a predetermined percentage of the time. When analyzing data, analysts frequently use confidence intervals that include 95% or 99% of the expected observations. Inferring that there is a 95% probability that the true value falls within that range is possible if a point estimate from a statistical model of 10.00 with a 95% confidence interval of 9.50 - 10.50 is produced.

Confidence intervals are a tool used by statisticians and other analysts to understand the statistical significance of their estimates, inferences, or predictions. One cannot satisfactorily assert that a result from data obtained through testing or experimentation is to be attributed to a specific cause rather than chance if a confidence interval contains the value of zero (or some other null hypothesis).

If the rod has a cross sectional area A2 and the material has a modulus of elasticity E2, the force in the rod is:

Frod = (Fbeam*A₂*E₂*I1)/(48*E₁*L^2) or Frod = -V_A*(A₂*E₂)/(I1*L^2)

To determine the force in the rod, we need to apply the principles of equilibrium and compatibility of deformations.

First, let's consider the equilibrium of forces acting on the rod AC. The only forces acting on the rod are the vertical reaction at A and the unknown force in the rod. Since the rod is in static equilibrium, the sum of vertical forces must be zero. Therefore, we have:

Frod + V A = 0

where Frod is the force in the rod and V_A is the vertical reaction at A.

Next, let's consider the compatibility of deformations between the beam and the rod. Since they are connected at point A, they must have the same vertical displacement at that point. We can use the equation of the deflection curve for a simply supported beam with a concentrated load at the center to determine the vertical displacement at point A:

δ_A = (Fbeam*L^3)/(48*E₁*I₁)

where δ_A is the vertical displacement at point A, Fbeam is the unknown concentrated load on the beam, L is the span of the beam, and E₁ and I₁ are the modulus of elasticity and cross-sectional area moment of inertia of the beam, respectively.

We can also use the equation for the elongation of an axially loaded member to determine the vertical displacement at point A due to the force in the rod:

δ_A = (Frod*L)/(A₂*E₂)

where Frod is the force in the rod, A₂ is the cross-sectional area of the rod, and E₂ is the modulus of elasticity of the rod.

Equating these two expressions for δ_A, we get:

(Fbeam*L^3)/(48*E₁*I₁) = (Frod*L)/(A₂*E₂)

Solving for Frod, we get:

Frod = (Fbeam*A₂*E₂*I₁)/(48*E₁*L^2)

Substituting this expression for Frod into the equilibrium equation, we get:

(Fbeam*A₂*E₂*I₁)/(48*E₁*L^2) + V_A = 0

Solving for Fbeam, we get:

Fbeam = -(48*E₁*L^2*V_A)/(A₂*E₂*I₁)

Therefore, the force in the rod is:

Frod = (Fbeam*A₂*E₂*I₁)/(48*E₁*L^2)

Frod = -V_A*(A₂*E₂)/(I₁*L^2)

Explanation:

Temperature of atmospheric air To = 25°C = 298 K

Free  stream velocity of air Vo = 25 m/s

Length and width of plate = 1m

Temperature of plate Tp = 125°C = 398 K

We know for air, Prandtl number Pr = 1

And for air, thermal conductivity K = 24.1×10?³ W/mK

Here, charectorestic dimension D = 1m

Given value of Reynolds number Re = 105

For laminar boundary layer flow over flat plate

= 3.402

Therefore, hx = 0.08199 W/m²K

So, heat transfer rate q = hx×A×(Tp – To)

The generator delivers current of 500.11 A

Explanation:

Given the data in the question;

mechanical energy delivered to the generator = 1500 hp

efficiency η = 80.0 %

terminal potential difference of the generator = 1790 V

we know that;

1 hp = 746 W

so

the mechanical energy delivered to the generator will be

Generator Input = ( 1500 × 746 )W = 1119000 W

So the generator output will be;

Generator Output = Generator Input × η

we substitute

Generator Output = 1119000 W × 80.0 %

Generator Output = 1119000 W × 0.8

Generator Output = 895200 W

So the Current will be;

\(I\) = Generator Output / terminal potential difference of the generator

we substitute

\(I\) =  895200 W / 1790 V

\(I\) =  500.11 A

Therefore, The generator delivers current of 500.11 A

The probability that one telephone call passes through the switchboard in three minutes is 1.49%.

Using the Poisson probability formula, we can calculate the probability of exactly one call passing through the switchboard in 3 minutes as follows:

P(X = 1) = (e^(-6) * 6^1) / 1!

Where

6 = 2 per minute * 3 minute

X is the number of calls passing through the switchboard in 3 minutes.

So, we have

P(X = 1) = (e^(-6) * 6^1) / 1!

= (0.00248 * 6) / 1

= 0.0149

Therefore, the probability that one telephone call passes through is approximately 0.0149, or about 1.49%.

In snooker, the maximum number of points that can be scored during a single frame is 147. This is achieved by potting all 15 red balls, each worth 1 point, and subsequently potting the colored balls in sequence: yellow (2 points), green (3 points), brown (4 points), blue (5 points), pink (6 points), and black (7 points). Each color is then returned to its original position and can be potted again for additional points.

The angle and wind speed mentioned in your question are not relevant to determining the maximum number of points in a snooker frame. The speed and direction of the balls are controlled by the player's shots, and the rug coating on the table doesn't affect the scoring.
