1. (42 points) A piston-cylinder device contains 6 kg of steam at 100°C with a quality of 50 percent. This steam undergoes two processes as follows: 1-2 Heat is transferred to the steam in a reversible manner while the temperature is held constant until the steam exists as a saturated vapor. 2-3 The steam expands in an adiabatic, reversible process until the pressure is 15 kPa. (a) (24 points) Fill in the table using the given and determined properties. You...

Can some one solve this question please
Q4) A steam turbine at steady state is operated at part load by throttling the steam to a lower pressure before it enters the turbine. Before throttling, the pressure and temperature are, respectively, 1.5 MPa and 320°C. After throttling, the pressure is 1 MPa. At the turbine exit, the steam is at 8 kPa and a quality of 90%. Heat transfer with the surroundings and all kinetic and potential energy effects can be...

A) Steam enters a horizontal pipe operating at steady state with a specific enthalpy of 2,663 kJ/kg and a mass flow rate of 0.1 kg/s. At the exit, the specific enthalpy is 1,531 kJ/kg. If there is no significant change in kinetic energy from inlet to exit, determine the rate of heat transfer between the pipe and its surroundings, in kW. B) Refrigerant 134a enters a horizontal pipe operating at steady state at 40°C, 3.1 bar and a velocity of...
