Saturated Pressure Temperature chart for R-22 shows 45 degF at 76 psig
65-45= 20 degF superheat
Answer:
Explanation:
They are altered by variables such as temperature hence making materials challenging when dealing with them.
Answer is given below
Explanation:
we know that some common types of throttling devices are
- Hard -throttling devices
- Capillary valve
- Constant pressure throttling devices
- Thermostatic expansion valve
- Float expansion valve
so here throttling devices commonly used in refrigeration and air-conditioning because
- To reduce the coolant pressure, the high pressure of the refrigerant from the condenser is necessary to reduce the evaporation to obtain evaporation at the right temperature
- To meet the refrigerated load, the throttling valve flows through the coolant to cool the load at high temperatures.
Answer :
<h3>Flow rate in pipe B is = 0.3094
</h3>
Explanation:
Given :
Length of pipe A 
m
Length of pipe B 
m
Flow rate through pipe A 
Diameter of pipe 
m
Velocity from pipe A,
Here, head loss is same because height is same.
Now rate of flow from pipe B is,
