Steam enters a two stage steady state turbine at 8 MPa and 500 C. It expands in the first stage to a state of 2 MPa and 350°C. Steam is then reheated at constant pressure to a temperature of 500°C before it enters the second stage, where it exits at 30 kPa and a quality of 98%. The net power output of the turbine is 3 MW Assume the surroundings to be at...

- Question 3 Superheated steam at a pressure and temperature of 60 bar and 450 degC undergoes adiabatic expansion through a turbine at a steady rate of 16.3 kg/s. The steam exits the turbine in a wet condition with a pressure of 0.34 bar and specific enthalpy of 2,355 kJ/kg. 25 points Determine the How Did I Do? How Did I Do? properties of the superheated steam at the turbine entrance (state 1): Specific volume, V: 0.0521 m^3/kg kJ/kg Specifio...

Homework 2 Problem 1: A piston-cylinder device initially contains 0.35-kg steam at 3.5 MPa, superheated by 7.4 C. Now the stream loses heat to the surroundings and the piston moves down, hitting a set of stops at which point the cylinder contains saturated liquid water. The cooling continues until the cylinder contains water at 200C. Determine (a) the final pressure and the quality (if mixture), (b) the boundary work, (c) the amount of heat transfer when the piston first hits...

Water is the working fluid in an ideal regenerative Rankine cycle with one open feed water heater, Figure 2. Upstream of the high pressure turbine superheated vapour with a mass flow rate of 90 kg/s entres the first-stage turbine at a pressure of 14 MPa Each turbine stage has an isentropic efficiency of 90%. The temperature of the inlet vapour is 520°C. The steam expands through the first-stage turbine to a pressure of 0.9MPa where some of the steam is...

7. Steam leaves an industrial boiler at 827.4kPa and 171.6°C (hf = 727.25 kJ/kg, hfg = 2043.2 kJ/kg ). A portion of the steam is passed through a throttling calorimeter and is exhausted to the atmosphere when the calorimeter pressure is 101.4 kPa and a temperature of 115.6°C (h= 2707.6 kJ/kg ). How much moisture does the steam leaving the boiler contain ? 8. During the polytropic process of an ideal gas, the state changes from 138 kPa and 5°C...
