Answer to Question #331582 in Mechanical Engineering for NITHIN

Question

Air refrigeration works between 1 bar and 5 bar pressure limits. The temperature of the air entering the compressor and expansion cylinder is 8+A0C and 20+B0C respectively. The expansion and compression follow the law pv1.3=Constant. Find the following: • The theoretical C.O.P of the refrigerating cycle. • If the load on the refrigerating machine is 10 tons, then find the amount of air circulated per minute through the system. Assuming the actual C.O.P is 50% of the theoretical C.O.P. • Length and diameter of the single-acting compressor run at 300 r.p.m and the volumetric efficiency are 85%.
