Solve it correctly please. I will rate accordingly.

Derive Detive the expression for efficiency of Reheat cycle and Compare with Rankine'cycle.

Give one example problem with solution of reheat regenerative cycle

An air-standard Brayton cycle has a pressure ratio of 12. Find the thermal efficiency of the cycle

Show given, complete solution, and diagram.  A steam power plant operates on the Rankine Cycle. The steam enters the turbine at 7 Mpa and 550 with a velocity of 30 m/s. It discharges to the condenser at 20kpa with a velocity at 90 m/s. Calculate the net workin kw for a flow of 37.8kg/s.  a. 23.23 Mw       c. 34.22 Mw b. 53.34  Mw     d. 46.54 Mw

Derive an expression for the optimum pressure, ratio of simple gas turbine plant and also find equation for maximum work output.

EX. 3: A petrol engine is supplied with a fuel of (41868 KJ/Kg) heating value. Cylinder pressure at (30%) of the stroke and (70%) of the stroke are (1.33 bar) and (2.66 bar) respectively. Assuming the compression isobying the Law PV=const. find the compression ratio if the relative efficiency compared with that of the ideal cycle is (50%). calculate the specific fuel consumption.

H.W1 A diesel engine has a compression ratio of 20:1 with an inlet of 95 kPa, 290 K, with volume 0.0005 m³. The maximum cycle temperature is 1800 K. Find the maximum pressure, the net work done and the thermal efficiency
