Unformatted text preview: area of the nozzle. 4. Saturated liquid R12 at 25oC is throttled to 150.9 kPa in your refrigerator. What is the exit temperature? Find the percent increase in the volume flow rate. 5. A steam turbine has an inlet of 2 kg/s water at 1000 kPa, 350oC and velocity of 15 m/s. The exit is at 100 kPa, x = 1 and very low velocity. Find the specific work and the power produced. 6. A compressor brings R134a from 150 kPa, 10oC to 1200 kPa, 50oC. It is water cooled with a heat loss estimated as 40 kW and the shaft work input is measured to be 150 kW. How much is the mass flow rate through the compressor? 7. A condenser (cooler) receives 0.05 kg/s R22 at 800 kPa, 40oC and cools it to 15oC. There is a small pressure drop so the exit state is saturated liquid. What cooling capacity (kW) must the condenser have?...
