! Required information Consider an ideal gas-turbine cycle with two stages of compression and two stages of expansion. The pressure ratio across each stage of the compressor and turbine is 3. The air enters each stage of the compressor at 300 K and each stage of the turbine at 1200 K. Use variable specific heats. Determine the back work ratio and the thermal efficiency of the cycle, assuming a regenerator with 79 percent effectiveness is used. The back work ratio is The thermal efficiency is [ %. 1%.

Assuming a compression ignition engine having a cut-off ratio of 2 and a compression ratio of 20. Before the compression stroke, air is at 100kPa, 20°C and a volume of 500 cm³. Determine (in kPa) the mean effective pressure of the cycle
650 kg/min of superheated steam at 13 Mpa, 582 deg. C enters the turbine and initially expands isentropically to the pressure of 9.2 Mpa. After partial expansion, the steam was reheated with the same pressure at 9.2 Mpa and leaves the first reheater at 520 deg. C. It is once again expanded for the second partial expansion to a pressure of 5.4 Mpa where extraction of steam occurs. The remaining steam was reheated to a pressure of 4.9 Mpa and regained a temperature of 470 deg. C after the addition of heat in the second reheater. The final and complete isentropic expansion was executed until it reached an exhaust pressure of 0.04 Mpa. Draw the corresponding schematic diagram and its T-S diagram. Solve the following -total heat in MW -quality of steam before the condenser. -enthalpy entering the second reheater in KJ/Kg. -rejected heat by the condenser in MW. -net cycle work for the system in kJ/kg. -total reheating for the system in KW -net efficiency for the cycle. -turbine-generated…

A Joule cycle is used for electricity production in a power plant. Air is introduced to the cycle from the ambient with a pressure of 1 bar, and a temperature of 20 °C. The air is compressed in compressor C1 and is thereafter cooled down to 30 °C. The air is compressed again in compressor C2. The air passes through a regenerator where it is heated by exhaust gases. Heat is added by combustion of fuel in combustion chamber CC1. The air is thereafter expanded in turbine T1. The air is reheated in combustion chamber CC2. The air is expanded in turbine T2, and the exhaust gases after the turbine pass through the regenerator and is finally vented to the ambient. Turbine T2 is driving compressor C2. The net work from the cycle is produced by the difference between the work produced by turbine T1 and compressor C1. The regenerator efficiency is 0.80, the isentropic efficiency of the compressor is 0.83, and for the turbine 0.85. The temperature after CC1 and CC2 is tCC, the pressure after…
