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...

Problem 2_Skills: Setup, T-s, mass and energy balances A steam power plant operates on the reheat regenerative Rankine cycle with a closed feedwater heater. Steam enters the turbine at 8 MPa and 500°C at a rate of 15 kg/s and is condensed in the condenser at a pressure of 20 kPa. Steam is reheated at 3 MPa to 500°C. Some steam is extracted from the low-pressure turbine at 1.0 MPa, is completely condensed in the closed feedwater heater (x3 0),...

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...

In a small power plant, a steam at a rate of 2 kg/s and 4000 kPa enters a two stages steady-flow steam turbine. During the first stage, the steam expands in the turbine while doing work until the turbine exit pressure is 500 kPa. At that point, 10% of the steam is removed from the turbine for other uses. During the second stage, the remaining portion of steam, the 90% of the steam, continues to expand until it exits the...
