Later that day, the Director of Sales, Chris, calls you. "We have a problem. The folks in accounting did a random audit on expense accounts, and it turns out that there were some irregularities on Terry Stafford's expense account statement last month. She used a company credit card for several meals with clients during a business trip. That part's okay, but then she also submitted the receipts for reimbursement on her expense report. So, we paid the credit card bill and also reimbursed her for the meals on her expense report. She was double-dipping."

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
