Resistance occurs when the flow of charge through a wire is hindered. Resistance of flow of charge increases where the cable length increases .In a longer cable the charge carriers and the atoms in the cable collide more resulting to higher resistance.

The correct answer choice is: False.

The first answer is incorrect because resistance to flow of charge in a cable has a direct relation with length of cable in that increase in length of conducting cable will result to increase in resistance to flow of charges through the cable, not decrease in resistance.

The suggested methods to remove water from under the oil level in a compressor are: Consulting the manufacturer's recommendations or seeking professional assistance may be advisable in certain situations.

Perform a deep vacuum and vibrate the compressor casing: This method involves using a vacuum pump to create a low-pressure environment within the compressor. This can help remove the water by drawing it out through the suction or drain port. Vibration of the compressor casing can help break the surface tension of the oil and facilitate the removal of water.

Apply heat to the bottom: By applying heat to the bottom of the compressor, the water can be heated and converted into vapor. The vapor can then be removed by the vacuum system or other means, effectively separating it from the oil. However, it is important to ensure that the heat is applied safely and does not damage the compressor or its components.

Both methods aim to remove the water from under the oil level, but they employ different mechanisms to achieve this.

Consider the compression test sample illustrated below. Assume that you have 3 strain gauges that you can place on the bar. To maximize the measured output voltage for an applied force using three strain gauges, we can utilize a combination of vertical and horizontal placements on the compression test sample. The specific placement and configuration depend on the geometry and properties of the sample.

The Wheatstone bridge is a technique that uses electrical resistance to calculate the deformation of an item. In a Wheatstone bridge circuit, the strain gauges are placed in an arrangement to enhance sensitivity and cancel out temperature and other variations. The bridge circuit will be balanced when there is no pressure on the load cell, giving zero voltage output. When pressure is applied to the load cell, the bridge will be unbalanced, and the output voltage will be a measure of the strain on the cell.

Here's a description and sketch of how the gauges can be placed on the test specimen and in the Wheatstone bridge circuit:

Placement of Strain Gauges on the Test Specimen:

Gauge 1: Place one strain gauge vertically on one side of the test specimen, aligned with the direction of expected deformation when the force is applied. This gauge will experience tensile or compressive strain.

Gauge 2: Place another strain gauge horizontally on the opposite side of the test specimen, also aligned with the expected deformation direction. This gauge will experience shear strain.

Gauge 3: Place the third strain gauge diagonally across the specimen, oriented at a 45-degree angle relative to the other two gauges. This gauge will experience both tensile/compressive and shear strain.

[Sketch: The sketch would show the test specimen with the three strain gauges placed as described above.]

Wheatstone Bridge Circuit Configuration:

Connect Gauge 1 in a half-bridge configuration, where it is the active strain gauge and is connected to one arm of the bridge.

Connect Gauge 2 and Gauge 3 in a full-bridge configuration, forming an opposite arm of the bridge.

The fourth arm of the bridge can either be another identical Gauge 2 placed on the other side of the specimen or a precision resistor with the same resistance value as the strain gauges.

The bridge's excitation voltage is typically provided by a constant current source.

[Sketch: The sketch would show the Wheatstone bridge circuit with Gauge 1 in a half-bridge configuration, Gauge 2 and Gauge 3 in a full-bridge configuration, and the fourth arm of the bridge with either another Gauge 2 or a precision resistor.]

By placing the strain gauges in this manner and configuring them in the Wheatstone bridge circuit, we can obtain maximum sensitivity and cancellation of temperature effects and other common-mode signals. The combined measurements from all three gauges in the bridge circuit allow for comprehensive monitoring of the specimen's deformations under the applied force.

Answer:

Answer:

Explanation:

The summation of the forces in vertical direction

= Fb - Fd - w = 0 ∴ Fd = Fb - w  ----- ( 1 )

Fb ( buoyant force ) = Pair * g * Vballoon ------- ( 2 )

Pair = air density , Vballoon = volume of balloon

Vballoon = \(\frac{\pi D^3}{6}\) ,  where D = 4  ∴  Vballoon = 33.51 ft^3

g = 32.2 ft/s^2

From property tables

Pair = 2.33 * 10^-3 slug/ft^3

μ ( dynamic viscosity ) = 3.8 * 10^-7 slug/ft.s

Insert values into equation 2

Fb = ( 2.33 * 10^-3 ) * ( 32.2 ) *( 33.51 )  = 2.514 Ib

∴ Fd = 2.514 - 2.5 = 0.014 Ib ( equation 1 )

Assuming that flow is Laminar  and  RE < 1

Re = (Pair * vd) / μair   -------- ( 3 )

where:  Pair = 2.33 * 10^-3 slug/ft^3 ,  vd = ( 987 * 4 ) ft^2/s ,   μair = 3.8 * 10^-7 slug/ft.s

Insert values into equation 3

Re = 2.4 * 10^7 (  this means that the assumption above is wrong )

Hence we will use drag force law

Assume Cd = 0.5

Express  Fd using the relation below

Fd = 1/2* Cd * Pair * AV^2

therefore V = 1.39 ft/s

Recalculate  Reynold's number using  v = 1.39 ft/s

Re = 34091

from the figure Cd ≈ 0.5 at Re = 34091  

Finally calculate the rise time ( time taken to reach an altitude of 1000 ft )

t = h/v

  = 1000 / 1.39 = 719 seconds ≈ 12 mins

The mass of a spherical tank is the space contained in the tank. The mass of the spherical tank can be determined by first finding the volume of the tank, then using the relation of density, mass, and volume to find the mass.

From the given parameter:

The volume of the tank can be determined by using the formula:

\(\mathbf{V = \dfrac{4}{3}\pi r^3}\)

\(\mathbf{V = \dfrac{4}{3}\pi (0.25)^3}\)

V = 0.0655 m³

Using the relation that:

\(\mathbf{Density = \dfrac{mass}{volume}}\)

\(\mathbf{1000 \ kg/m^3= \dfrac{mass}{0.0655 \ m^3}}\)

mass = 1000 kg/m³ × 0.0655 m³

mass = 65.5 kg

The weight of the water can be determined by using the formula:

Weight = mass × gravity (i.e. acceleration due to gravity)

The weight of the water in spherical tank is 640.8 Newtons.

Given the data in the question:

Mass of water; \(m_w = \ ?\)

Weight of water; \(Ww = \ ?\)

Density \(p\) is simply the measure of the compactness of the mass of a substance. It is expressed as;

\(Density = \frac{Mass}{Volume}\)

To determine the mass and weight of the water in spherical tank,

we calculate the Volume of the spherical tank.

\(V = \frac{4}{3}\pi r^3\)

We substitute in our given values

\(V = \frac{4}{3} * \pi * (0.25m)^3\\ \\V = \frac{4}{3} * \pi * 0.015625m^3\\\\V = 0.0654 m^3\)

Now, we calculate the mass of the water; using the expression above.

\(Density = \frac{Mass}{Volume}\\Mass = Density * Volume\\\)

We substitute in our values

\(Mass = 1000kg/m^3 \ *\ 0.0654m^3\\\\Mass = 65.4kg\)

Hence, the mass of the water in spherical tank is 65.4kg.

Next we calculate the Weight which is expressed as;

\(Weight = mass\ *\ Acceleration\ of\ gravity\)

Where acceleration of gravity \(g = 9.8m/s^2\)

We substitute in our values

\(Weight = 65.4kg * 9.8m/s^2\\\\Weight = 640.8kgm/s^2\\\\Weight = 640.8N\)

B)  0.8897 M^3/ kg

c)  0.7737 m^3/kg

D)  746.542 k

E)  536.017 kj/kg

efficiency = 58% ( approximately )

Explanation:

Given Data :

Gas constant (R) =  0.287 kJ/ kg.K

T1 = 310 k

P1 ( Kpa ) = 100

r = 11.5 ( compression ratio )

rp = 1.95 ( pressure ratio )

A ) specific internal energy at state 1

 = Cv*T1 =  0.718 * 310 = 222.58 kJ / kg

B) Relative specific volume at state 1

= P1*V1 = R*T1 ( ideal gas equation )

V1 = R*T1 / P1 = (0.287* 10^3*310 ) / 100 * 10^3

V1 = 88.97 / 100 = 0.8897 M^3/ kg

C ) relative specific volume at state 2

Applying  r ( compression ratio) = V1 / V2

11.5 = 0.8897 / V2

V2 = 0.8897 / 11.5 = 0.7737 m^3/kg

D) The temperature (k) at state 2

since the process is an Isentropic process we will apply the p-v-t relation

\(\frac{T1}{T2} = (\frac{V1}{V2}^{n-1} ) = (\frac{P2}{P1} )^{\frac{n-1}{n} }\)

hence T2 = \(9^{1.4-1} * 310\) = 2.4082 * 310 = 746.542 k

e) specific internal energy at state 2

= Cv*T2 = 0.718  * 746.542 = 536.017 kj/kg
