Chapter 9, Problem 9.37P

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

. Steam enters the turbine at 10 bar. Output pressure P = 1 bar, knowing turbine efficiency is 80%. Find the state of the fluid leaving the turbine (If liquid or vapor, find temperature; If liquid-vapour mixture, find q). Calculate the work done per kg of steam entering:a. The inlet steam temperature is 250oC .b. The inlet steam temperature is 325oC

The Siemans SST-400 GEO steam turbine is employed in the cycle shown above. Operational information is are shown in the table. you can assume the turbine is adiabatic and you can ignore the KE & PE terms. you can assume that the pump operation is isentropic. the surrounding temperature is 25°C based on the table information: a.Calculate the mass flow of steam [96.5kg/s] b.Find the isentropic efficiency of the turbine [0.836] c.What is the rate of entropy generated (kW/K) in the turbine? [28.26kW/K] d.Calculate the thermal efficiency of the power plant [0.199]

Steam is supplied to a two-stage turbine at 48 bar and 400 °C. It expands in the firstturbine until it is just dry saturated, then it is re-heated to 400 °C and expandedthroughthe second-stage turbine. The condenser pressure is 0.04 bar what is the pressure in bar at state 4 to 3 decimal places? what is the specific entropy in kJ/kg-K for state 5 to 4 d.p.?

I need answer in handwritten

Q3: A distillation column is separating acetone(more volatile component) from ethanol. As pictured, there are two feeds with flow rates F₁=100 mol/hr and F₂-200 mol/hr. Feed 1 has z₁-0.7 and is saturated liquid. Feed 2 has z2 0.4 and is a superheated vapor (q=-0.1) where approximately 1 mol of liquid will vaporize on feed stage for each 10 mol of feed. We desired xd-0.95 and xw-0.05. How many stages are needed to achieve this separation? Ln/Vn=0.64.

9. A main feed pump receives water from booster pump at 230 deg. Fahrenheit and 55 psia and delivers the water at 1000 psia. Assume the process to be isentropic and find the work done in Btu/lb. [Hint Do not use the formulas of the processes of ideal gas since the fluld here is water)

Air temperature 30 ° C pressure 1 bar flows into the ideal gas turbine cycle by a pressure ratio air compressor (r). 12 The hot gas discharge temperature from the combustion chamber is 1200 K. The air flow in a constant cycle is 60 kg/s a. Draw the diagram T-5 of this cycle b. Find the net power output (kW). C. Find the thermal efficiency of this cycle
