Draw a schematic diagram of each problem with labels of states of a substance; Assign STATE 1 at the inlet of a high-pressure turbine. The states must be arranged in a chronological order; Plot each cycle in a t-s diagram with thestates consistent to the states assignment in the schematic diagram; Water is the working fluid in a cogeneration cycle that generates electricity and provides heat for campus buildings. Steam at 4 MPa, 400 0C, enters a two-stage turbine with a mass flow rate of 0.80 kg/s, from which a of 0.15kg/s is extracted between the two stages at 0.20MPa to provide for building heating, and the remainder expands through the second stage to the condenser pressure of 0.01 MPa. Condensate returns from the campus buildings and passes through a trap into the condenser, where it is reunited with the main feedwater flow. Saturated liquid leaves the condenser at 0.01MPa. Both turbine and pump have 90% efficiency. Determine, in kW, the ff:(a) rate of heat transfer to the working fluid passing through the steam generator;
