Problem 3 In modern high-speed compression ignition engines, fuel is injected into the combustion chamber much sooner than in early diesel engines. That means, heat is added partly at constant volume and partly at constant pressure. The advantage of this modification is that more time is available for the fuel to completely combust. The ideal dual cycle consists of the following operations: • Process -: Isentropic compression • Process -3: Addition of heat at constant volume. • Process - Addition...

Problem 8.021 Tutorial S1 Water is the working fluid in an ideal Rankine cycle with reheat. Superheated vapor enters the turbine at 12 MPa, 440C, and the condenser pressure is 8 kPa. Steam expands through the first-stage turbine to 1.2 MPa and then is reheated to 480°C. Assume the pump and each turbine stage has an isentropic efficiency of 85% and 92%, respectively. Determine for the cycle: (a) the rate...
