Refrigerant 22 passes into a device operating at steady statewith a single inlet and two outlets. The flow at the device inlethas a pressure of 60 lbf/in2, a temperature of 40°F, and a velocityof 2 ft/s. The inlet has an area of 2 ft2. The flow at the firstoutlet has a pressure of 60 lbf/in2, a temperature of 120°F, and avelocity of 3 ft/s. The first outlet has an area of 1 ft2. The flowat the second outlet has a temperature of 120°F. The deviceconsumes 70 hp of power. Determine the mass flow rate in lb/s andpressure of the flow in lbf/in2 at the second outlet. Assume thedevice is well-insulated and neglect kinetic and potential energychanges.
please donot copy and paste i will rate you negative .. takecare of sign of work and explain in details
