  1. Steam is produced at 20 bar and some unknown temperature. A small amount of steam is bled off and goes through an adiabatic throttling valve to 2 bar. The temperature of the steam exiting the throttling valve is 1200C.What is the value of the specific entropy of the steam before entering the throttle (ANS: 5.974 kJ/kg.0C).

The Assignment: Water at a pressure of 15 bar at a temperature of 30°C enters a boiler, where it is heated to 250°C at constant pressure. Steam leaving the boiler passes into a throttle which reduces the pressure to 10 bar. The steam is then passed through a small turbine, exiting at atmospheric pressure at 110°C. Please draw a schematic diagram. 1. How much heat is added per kg to the water by the boiler? 2. Find the temperature of...

Steam at 4.5 MPa and 500 C enters the turbine with a velocity of 60 m/s and its mass flow rate is 5,000 kg/h. The steam leaves the turbine at a point 3m below the turbine inlet with a velocity of 350 m/s. The heat loss from the turbine is 100,000 kJ/hr and the shaft work produced is 950hp. A small portion of the exhaust steam from the turbine is passed through a throttling valve and discharges at atmospheric pressure....

1. You are to do a preliminary design study for a small demonstration steam turbine power plant. - Steam will be provided by a small steam generator fired by natural gas.   - Your system will take in steam at 30 bar and 400 oC. - The steam passes through a two stage turbine. At a pressure of 10 bars, the steam leaves the first stage of the turbine and will pass through a reheat loop in the steam generator which...
