A steam turbine installation of 60 MW capacity has steam entering turbine at 7 MPa, 500oC with steam bleeding at 2 MPa and 0.2 MPa for feed heating. Remaining steam at 2 MPa is reheated upto 480oC. Steam finally leaves turbine at 36 mm Hg (absolute). Give layout, mass fraction of steam bled out per kg of steam generated, cycle efficiency and mass flow rate of steam entering turbine.
Steam Plant A steam power plant operates according to the Rankine cycle between a boiler pressure of 4 MPa and condenser pressure of 6.5 kPa. The steam has a temperature of 380 °C at inlet to the first turbine. It is just dry saturated on leaving this turbine for reheating to its original inlet temperature, before passing through a second turbine to the condenser. Draw a T-s diagram to illustrate the reheat cycle, neglect feed-pump terms and calculate the Rankine efficiency and specific steam consumption.
yale L 15 A gas power cycle uses air as the working fluid and has two turbine sections as shown in the figare below. The power produced by Turbine I is used to drive the compressor, and Turbine 2 produces output power W. Air enters the compressor with a semperature of 290 K and a mass flow rate of -2 (kgs] (State I); the air exits the compressor at 44SK (State 2). Heat is transferred from a high- temperature thermal reservoir, Ta- 1400 [K), to Heat Exchanger 1 at a rate Q,- The lemperature of the air is raised to 1100 [K] (State 3) as it flows through Heat Exchanger 1. The air enters Turbine I where it is expanded to State 4. The flow then proceeds to Turbine 2 and exits with a temperature of 500 (K] (State 5). Heat is then removed from the air through Heat Exchanger 2 at a rate Q which is rejectod to the low-temperature thermal reservoir, TL-200 (K).

Hello, Please solve this problem, and explain a little bit for me to review. Thank you very much
Carnot cycle heat pump utilizes R-134a as the working fluid. Heat is transferred from the fluid at 100 F, and during this process the refrigerant changes from saturated vapor to saturated liquid. Heat transfer for the refrigerant takes place at 20 F. You are asked to do the following: (a) Show and describe the cycle on a T-s diagram (b) Calculate the quality at the beginning and at the end of the isothermal process at 20 F (c) Determine the coefficient of performance for the cycle.
