(20 pts each) 1. A compressor or turbine problem with an ideal gas The KE and PE changes can be neglected. I may add some heat transfer. Watch the sign on the heat transfer…is it a loss or gain?? So the governing equation would like that above. For an ideal gas, h 2 -h 1 = C p (T 2 -T 1 ) The mass flow rate may have to be determined from the ideal gas relationship if volumetric flow is given in lieu of mass flow. Pv = RT, mass flow = volumetric flow/v 2. An ideal diesel cycle problem…integrated with an electric generator. Cold air standard assumptions You might be given r and rc and the efficiency of the electric generator and asked to find the fuel consumed by the diesel cycle to provide a given power output from the generator. OR you might be given the power output from the generator and have to find the flow rate of cooling water and pipe size for the radiator connected to the diesel engine. ) ( 1
