A compressor installed at a whalf for loading of container ships provides 6 bar.

Question

A compressor installed at a whalf for loading of container ships provides 6 bar.g pressure into the pressure reciever. The compressor is moved to a site that is 5000 ft above sea level (atmospheric pressure 0.85 bar.a) in the mountains.

What is the discharge revised discharge pressure (guage pressure) of the compressor ?

Assume no change in temperature.

Is the assumption of change in temperature valid for calculating the discharge pressure of the compressor ?

The temperature at the whalf is 35 oC and in the mountains is 19 oC, what is the reduction in volumetic output from the compressor ?

Explanation / Answer

A compressor installed at a whalf for loading of container ships provides 6 bar.g pressure into the pressure reciever. The compressor is moved to a site that is 5000 ft above sea level (atmospheric pressure 0.85 bar.a) in the mountains

the discharge revised discharge pressure (guage pressure) of the compressor :

= (6
