A gas with flow rate of 100 MMSCFD of needs to be compressed from 800 to 8,000 psia. The inlet temperature is 90°F. How many stages are needed to compress the gas? Assume a 3% pressure loss between stages. Calculate the required HP. What type of compressor would you recommend? Assume n, = 0.9, and Em = 0.9. Yg = 0.62, k = 1.32.

A single acting, two stage, reciprocating compressor receives air at 100 KPa and air capacity of 0.05 m3/sec and delivered at 400 KPa. The clearance volume is taken to be 8 %. The compression and expansion process is isentropic with compressor mean piston speed of 150 meter/min. Assuming that each piston has the same amount of stroke. no pressure drops at the suction and discharge ports of the compressor and perfect intercooling, determine: a) The piston diameter in centimeters b) The total power required in Kilowatts c) The heat loss at the intercooler in Kilowatts

, A single stage, double acting air compressor is required to deliver 14 m³ of air per min measured at 15 °C and 1.013 bar. The delivery pressure is 7 bar and the speed 300rev/min. Take the clearance volume as 5% of the swept volume with a compression index of n=1.3. Calculate the swept volume of the cylinder, the delivery temperature and the indicated power.

The compression process follows PV1.35 = C. What is the engine Kw power needed to drive the unit if the combined engine-compressor efficiency is 84%?

For air properties use online source: https://www.peacesoftware.de/einigewerte/luft_e.html  The compressor is operating at steady-state increasing pressure of R-22 refrigerant from 4 bars to 14 bars. Temperature was rising during the process from 12C to 90C. The inlet volumetric flow rate is 1 m3/min and inlet diameter is 0.03m. At the exit the diameter is the same. Heat flow to the surroundings can be neglected. Determine: a.Mass flow rate [kg/s]   SHOW AND EXPLAIN ALL STEPS PLEASE
