I need help on this assignment: Exhaust gases from the turbine of a simple Brayton cycle are quite hot and may be used for other thermal purposes. One proposed use is generating saturated steam at 110℃ from water at 30℃ in a boiler. This steam will be distributed to several buildings on a university campus for space heating. A Brayton cycle with a pressure ration of 6 is to be used for this purpose. Plot the following:(a) The mechanical power produced,(b) the flow rate of the produced steam,(c) the maximum cycle temperature, all as functions of the rate at which heat is added to the cycle.
A reheat cycle with two stages of reheating is executed with steam expanding initially from 200 bar (20 Mpaa) and 540 deg C. The 2 reheater pressures are 40 bar (4 Mpaa) and 10 bar (1 Mpaa) and the steam leaves each reheater at 540 deg C. Steam is bled in between two reheating sessions at a pressure equal to 20 and 15 bars into 2 open feedwater heaters. Condensation occurs at 60 deg C. All expansion and compression efficiencies are 90 %. There is a total of 10.3 kg/sec of steam (total mass flow rate m) circulated in the cycle. Answer the following: fill up the blanks in the items below: Actual Rankine cycle efficiency % using Qa’ and Qr’ values Answer: _____________ If the generator efficiency = 95%, brake engine efficiency = 90% what is the plant capacity in MW?

Answer the following questions correctly and please provide complete and readable solutions. Please Explain.
Superheated steam from the boiler expands in the turbine from inlet pressure p₁ of 50 bar and temperature 7 of 487 °C to condenser pressure p2 of 18 kPa. In the condenser, the steam condenses to saturated water. The isentropic efficiency of the turbine ns is 78.0 %. The mass flow of steam 9m,h is 140 kg/s. In the boiler, heat flow rate to the circulating fluid (water/steam) is 458 MW. Read from h,s-diagram and calculate: 1. Enthalpy of the superheated steam h kJ/kg (with zero decimal accuracy) 2.

It is known that the boiler pressure reading on the main header is 8 bar, the boiler feed water temp is 30oC, the use of coal as boiler fuel (1 kg coal = 6300 Kcal) for 24 days is 45000 kg. Steam flows from the main header to the branch header in the production line and the total steam flowmeter reading at the branch header is 38788 kg for 24 days with a pressure reading on the branch header is 7.5 bar. If the use of boiler feed water is 7000 liters/day, how to calculate: 1. Total steam usage per day in Kcal?2. The amount of coal used per day in Kcal?3. The amount of steam usage at the header branch in Kcal?
DESIGN a steam power plant that produces 70 MW of power. The plant should have an open heater and a reheater operating simultaneously utilizing saturated steam from the partial expansion of steam in the turbine. The remaining steam is reheated to the inlet temperature of steam when it enters the turbine. Another open heater is used to bled saturated steam when the steam partially expands in the turbine after reheating, remaining steam is expanded to the exhaust pressure of the turbine. Other pertinent data are as follows: steam turbine: inlet pressure – 6.6 MPa; inlet temperature - 420 C; exhaust pressure – 10 KPa; stages of turbine – all pressure compounded stage; pumps – 90% efficient; shaftings – 75%% efficient; generator – 95% efficient. DRAW a line diagram of the design plant indicating the pressure, temperature and enthalpy at each point and specify the following: a) the mass requirement of the steam plant in kg/hr b) the masses extracted in kg/hr and c) the plant thermal…
