E.4) A cylinder and piston assembly contain water at 105°C and 85% quality, with a volume of one liter. The system heats up, causing the piston to rise and encounter a linear spring. At this point the volume is 1.5 liters, the piston diameter is 150 mm, and the spring constant is 100 N/mm. Heating continues, so the piston compresses the spring. Determine the pressure in the cylinder when the temperature reaches 600°C.
A vertical cylinder is fitted with a freely-moveable piston of 0.2 m diameter and contains 0.1 kg of (liquid) water. At the initial State 1, the water remains in equilibrium as saturated liquid at 15 "C with the piston applying a pressure of 7.0 bar on the water in the cylinder. The water is then slowly heated until the piston rises to a height of 0.6 m above its initial position to reach the equiliorium at State 2. The piston is now held fixed at this location and the cylinder contents are further heated to increase its pressure to 15 bar at State 3. (a) Find the volume of water at State 1. (b) Show that the cylinder contains saturated (wet) steam at State 2 and determine its dryness fraction at this state. (c) Find the steam temperature at State 3. On a T-v diagram, indicate the process undergone by the contents of the cylinder from State 1 to State 3.

A piston-cylinder device contains an ideal gas of nitrogen. At the initial state, the volume is V1= 1.00 m3, the pressure is p1= 400.00 kPa, the temperature is T1= 300.00 K. An electric heater within the device is turned on for a time of Δt = 5.00 min. The current is I = 3.00 A, and the source voltage is V = 120.00 V. During the heating process, the gas expands, and a heat loss of Qout = 2.80 kJ occurs. The gas constant is R = 0.297 kPa·m3/(kg·K), and the room temperature specific heat at constant pressure is cp =1.039 kJ/(kg·K). Calculate the electrical work done on the gas, Wele__________ (kJ)
