steam flowing at a rate of 16 kg/s expands through a turbine operating at staedy state. The rate of transfer out of the turbine is 600 kW. The steam enters at 2 MPa, 320 C and exits to the atmosphere at 80 kPa and a quality of 0.7, neglecting the cahnge of kinetic and potential energy. Determine: the exit temperature in C.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m

Apiston-cylinder device contains 0.1 m3 of liquid water and 0.9 m3 of water vapor in equilibrium at 800 kpa. heat is transferred at constant pressure until the temperature of water reaches 350 °c. determine (a) the quality of water at the initial state (b) the work associated with this process, (c) the heat associated with this process.
