Thermo Final Exam open book open notes 2hrs 1. (10pts) A power plant can be described by an ideal Rankine cycle without any irreversibility's. he boiler produces superheated steam at a pressure of 200 bars and temperature of 600c (1). The steam expands adiabatically (and isentropicly) thru a turbine exiting as a saturated vapor/liquid mixture at pressure of 0.1bar (2). The mixture passes thru a condenser (P-0.1bar) until it is all saturated liquid (3). It is then pumped adiabatically to...

In a closed rigid vessel that does not have any type of work interactions with the surroundings the amount of heat that needs supplied to heat a liquid inside the container can be determined by the change in internal energy. Suppose you have a sealed pan with 1 liter of water at 20 °C and 100 kPa that you want to heat to 70 °C. Do the following: a. Represent the process on a T-v diagram. Indicate T (°C) and...

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...

QUESTIONS 1. Refrigerant-134a is cooled by water in a condenser. The refrigerant enters the condenser at a pressure of 1 MPa and a temperature of 70°C at a flow rate of 6 kg / min and exits at a temperature of 35 °C. Cooling water enters the condenser at 300 kPa pressure and 15 °C temperature and exits at 25 °C temperature. By neglecting pressure losses, Calculate; a) mass flow of cooling water b) the heat transfer from the refrigerant...
