Steam at 10 MPa and 550 o C enters reheat-regenerative engine and expands to 3 MPa where m 1 is extracted for feedwater heating, the remainder is withdrawn and and reheated to 550 o C. Expansion then occurs to 1.8 MPa, where m 2 is extracted for feedwater heating with the remaining steam withdrawn and reheated to 550 o C. The third extraction for feedwater heating is at 0.1 MPa. Condenser is at 45 o C. Calculate: a) m 1,m 2, m 3, b) ideal work of the engine, c) boiler feedwater pump work, d) Heat Added, e) thermal efficiency of the engine , f) thermal efficiency of the cycle, g) heat rate.

A reheat cycle with two stages of reheating is executed, with steam expanding initially from 90 bar and 530°C. The two reheater pressures are 10 bar and 0.6 bar, and the steam leaves each reheater at 480°C. Condensation occurs at 0.03 bar. For an ideal cycle, find the e in %.
A steam turbine is supplied with steam at 20.6 bar and 95°C of superheat and expand to 0.0343 bar. Steam is bled of 4.9, 1.373, and 0.275 bar, the bled steam being cascaded from heater to heater until it discharges through a drain cooler to the condenser. Assuming that the turbine expansion is isentropic and the drain cooler raises the combined heater condensate to condenser temperature, determine the following: The thermal efficiency in percentile. The steam consumption of kg per kW·hr without feed heating.
I need the workings ASP the answers are there questionn 4 4. A boiler produces 6 tonnes/hour of steam at a pressure of 1.8 MPa and a temperature of 250ºC.Feedwater enters at a temperature of 39ºC.

ANSWER QUESTION NUMBER 4 ONLY
Steam is generated at 4.10 Mpa and 440°C and condensation occurs at 0.105 MPa a. For a Rankine engine operating between these limits, computethe thermal efficiency and the heat rate b. Considering that a Rankine cycle occurs between same limits, determine QA, QR, Wnet and eth c. What mass flow rate is required for a net output of 30 000 kW Don't answer the given problem, just give me the schematic diagram and t-s diagram of the given problem
Consider a cylinder of a gasoline engine at the beginning of the compression cycle, duringwhich a fuel/air mixture (for our purposes mostly composed of nitrogen and oxygen, i.e.an ideal gas of diatomic molecules) at 300 K and 1 bar is compressed down to one-tenthvolume (compression ratio of 10:1). Assume that the compression is rapid so no heatexchange occurs with the environment. Calculate the pressure and the temperature ofthe compressed gas. In a diesel engine, the compression ratios are typically much higher;redo the same calculation with a compression ratio of 20:1.
