What is the minimum required CFM from a compressor which produces 120 psi?Calculate the required size of a receiver that must supply air to a pneumatic system consuming 30 scfm for 15 min between 140 psi and 110 psi before the compressor resumes operation. Group of answer choices 301 ft3 356 ft3 221 ft3 210 ft3 231 ft3A single-stage, single-acting air compressor with runs at speed 600 rpm. It has a polytropic index of 1.26. The induced volume flow rate is 7.2 cubic meters per min and the air must be delivered at a pressure of 697 kPa. The free air conditions are 101.3 kPa and 16 degrees Celsius. The clearance volume is 6% of the stroke volume and the stroke/bore ratio is 1.6/1. Calculate the delivery air temperature in degree Celcius to one decimal place.
