Answer:
a) Decrease
b) Decrease
c) Decrease
d) Decrease
Explanation:
Ti= 200°F ,
Te = 170°F
Area of heat exchanger = 
= 20π
<u>A) when The flow rate of the cooling fluid is increased</u>
Temperature of process stream will decrease and this is because the tube side heat transfer coefficient will increase and this will increase the rate of heat transfer thereby decreasing the temperature of the process stream.
B) <u>when There are 200 tubes that are 1.0-in. OD and 20.0ft long</u>
The temperature of the process stream will decrease and this is because the heat transfer coefficient will increase likewise the heat transfer rate
C) <u>When The number of shell passes is doubled</u>
This will cause an increase in the overall length of the shell, an increase in velocity of constant volumetric flowrate, hence the Temperature of the process steam will decrease as well
D)<u> When The tube material is changed to copper.</u>
Due to the high thermal conductivity of copper when compared to steel , switching to copper will cause a decrease in the temperature of the process steam
Answer:
Explanation:
Given that
Unit cell is in FCC
Here given direction is not clear visible so we take direction [001].
We know that linear density(LD) given as
![LD=\dfrac{Number\ of\ atoms\ in\ the\ direction\ vector}{d_{[001]}}](https://tex.z-dn.net/?f=LD%3D%5Cdfrac%7BNumber%5C%20of%5C%20atoms%5C%20in%5C%20the%5C%20direction%5C%20vector%7D%7Bd_%7B%5B001%5D%7D%7D)
So the number of atom will be 1/2 in direction [001]
In FCC
Answer:
This doesn't represent an equilibrium state of stress
Explanation:
∝ = 1 , β = 1 , y = 1
x = 0 , y = 0 , z = 0 ( body forces given as 0 )
Attached is the detailed solution is and also the conditions for equilibrium
for a stress state to be equilibrium all three conditions has to meet the equilibrum condition as explained in the attached solution
The spacing between sidebands is equal to 6 kHz.
<u>Given the following data:</u>
- Modulating signal = 3 kHz.
- Carrier frequency = 36 MHz.
<h3>What is a sideband?</h3>
A sideband can be defined as a band of frequencies that are lower or higher than the carrier frequency due to the modulation process. Thus, it will either be lower than or higher than the carrier frequency.
Generally, the frequency of the modulating signal is equal to the spacing between the sidebands. Therefore, a modulating signal of 3 kHz simply means that the lower sideband is <u>3 kHz</u> higher while the upper sideband is <u>3 kHz</u> lower.
Spacing = 3 kHz + 3 kHz = 6 kHz.

Answer:
Skeletal muscle
Explanation:
These classifications describe three distinct muscle types: skeletal, cardiac and smooth. Skeletal muscle is voluntary and striated, cardiac muscle is involuntary and striated, and smooth muscle is involuntary and non-striated.
