Chapter 9, Problem 9.30P

Steam at 6.2 MPa and 480°C is received by a regenerative engine. Extractions for feedwaterheating occurs at 3 MPa and again at. 1.4 MPa,with the remaining steam expanding to0.0065 MPa. For the ideal engine with a throttla flow of 54,500 kg/h, find the hourlyquantities of steam ex-tracted, the turbine work in kW, and the thermal efficiency. For an ideal cycle through the same states, calculate Q and e。

A Steam power plant uses a Rankine cycle to produce electrical power. The boiler pressure is 2 MPa and the temperature at the turbine inlet is 300C. The pump inlet pressure is 0.025 MPa and the entropy is 0.8931 kJ/kg-k. The turbine gives 1MW of work to the generator. Find the dryness of the steam at turbine exit, Wp, Qa, Qr, Wt, Wnet, efficiency, SR, and mass flow rate of steam. (84.65%, 2.0143 kJ/kg, 2749.56 kJ/kg, 1986.15 kJ/kg, 765.42 kJ/kg, 763.41 kJ/kg, 27.76%, 4.7157 kg/kWh, 1.3064 kg/s) -Draw the T-S diagram with properly labelled points and solve the problems. Show your COMPLETE solution - Use the Steam Table provided if necessary.

The turbine section in a jet engine receives gas (assume air) at 1200 K, 800 kPa with an ambient atmosphere at 80 kPa The turbine is followed by a nozzle open to the atmosphere and all the turbine work drives a compressor receiving air at 85 kPa, 270 K with the same flow rate Find the turbine exit pressure P. so the nozzle has an exit velocity of 800 m/s.
