Sessions: tuesday and thursday 2:30 pm 4:30 pm (203 tureaud) Office hours: mtwthf 11:45 am 1:15 pm (outside 2104 pft) Examples: a steam power plant has a high pressure of 3 mpa and it maintains 60oc in the condenser. A condensing turbine is used, but the quality should not be lower than 90% at any state in the turbine. For a turbine power output of 8 mw find the work and heat transfer in all components and the cycle efficiency: a smaller power plant produces 25 kg/s steam at 3 mpa, 600oc in the boiler. It cools the condenser with ocean water coming in at 15oc and returned at 18oc so the condenser exit is at 50oc. Find the net power output and the required mass flow rate of ocean water: a refrigerator receives 500 w of electrical power to the compressor driving the cycle flow of r-134a.
