Solution :
Using the data table for refrigerant-134a at P = 120 psia
∴ 
For pressure, P = 20 psia
Change in temperature, 
Now we find the quality,
The final energy,
Change in internal energy
= 38.09297-40.5485
= -2.4556
OA bloom is smaller than a bar
Hydraulic radius is caused by pressurized hydrogen air so that should mean the answer is hydraulic radius
Answer:
b)False
Explanation:
A battery is a device which store the energy in the form of chemical energy.And this stored energy is used according to the requirement.So battery is not a electromechanical device.Because it does have any mechanical component like gear ,shaft flywheel etc.
A flywheel is known as mechanical battery because it stored mechanical energy and supply that energy when more energy is required.Generally fly wheel is used during punching operation.
