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...

2. A piston-cylinder device maintain a constant pressure of 800 kPa while containing 20 kg of saturated water vapor. The system is heated with a resistance heater for 10 min at a current of 8 A at the standard wall voltage of 120 V. In that time, 3.2 kJ of heat is lost through the walls. What is the temperature at the heated state? 3 5-18E Hydrogen is contained in a piston-cylinder device at 14.7 psia and 15 ft. At...

(THERMODYNAMICS) A vertical cylinder fitted with a frictionless piston contains 1.5 kg of H2O initially at 100 °C, 400 kPa. If the volume of the system reaches 0.5 m3, the piston hits a set of stops and is restrained from further upward travel. The system is heated to 200 °C. (Use saturated water tables, steam tables, and superheated tables as necessary) a) If the piston reaches the stops, determine the temperature and pressure when the piston first touches but exerts no force...

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...

A mass of 5 kg of saturated liquid-vapor mixture of water is contained in a piston- cylinder device at 125 kPa. Initially. 3 kg of the water is in the liquid phase and the rest is in the vapor phase. Heat is now transferred to the water, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches 300 kPa. Heat transfer continues until the total volume increases by 10%. We denote the...
