Provide a complete given and computation. Include all the decimals. There are received 68,000 kg/h of steam by an ideal regenerated engine, having only one heater, of which the heater receives 15,400 kg/hr the condenser receives the remainder at 0.007 MPa. If the heater pressure is 0.96 MPa, find the state (quality or "SH) of the steam (a) at the heater entrance and (b) at the condenser entrance.
Q2:- Multi-evaporator system with single compressor and individual expansion valves used refrigerant 143a at two different temperatures with a single compressor and a single condenser. The low-temperature evaporator operates at -40 °C with saturated vapor at its exit and has a refrigerating capacity of 5 tons. The higher- temperature evaporator produces saturated vapor at 4 bar at its exit and has a refrigerating capacity of 3 tons.
