A vertical piston-cylinder assembly containing 0.3 Kg of steam, initially a vapor, is placed on a hot plate. Due to the weight of the piston and the surrounding atmospheric pressure, the pressure of the steam is 20 bar. Heating occurs slowly, and the steam expands at constant pressure until the final temperature is 200 °C. Show the initial and final states on T-v and p-v diagrams, and determine. (a) the volume occupied by the steam at each end state, in m3. (b) the work for the process.

A vertical piston-cylinder arrangement with a diameter of 120 mm contains water with a quality of 60%. The pressure is 3 bar. Initially the piston rests 40 mm above the bottom of the cylinder. Heat is then added until the volume is 3 times the original volume. (a) Determine the mass of the water in the cylinder
A vertically arranged piston-cylinder assembly with a mass and area of a piston given as 57 kg and 0.0106 m?, respectively is filled with 4 g of carbon dioxide (CO,). The initial volume and specific internal energy of the gas are 0.0047 m and 604 kJ/kg, respectively. The piston is exposed to the atmosphere and pressure of 100 kPa is exerted on the top of the piston by the atmosphere. The volume of the gas has decreased to 0.0024m when 2 kJ heat is transferred slowly from the gas to the surrounding (a) the pressure, in kPa, and (b) the final specific internal energy, in kJ/kg Assume: The local gravitational acceleration to be 9.81 m/s? Friction between the piston and the cylinder is neglected.
Agas filled in a piston-cylinder arrangement as shown in Figure 1 has a volume of 0.09 m at its initial equilibrium state. The gas is slowly heated through the bottom of the cylinder that allowed for the gas to expand at constant- pressure of 2068 kPa to a volume of 1.24 m. The change in internal energy of the gas is 0.21 kl. Ignoring the friction between the piston and the cylinder and assuming the atmospheric pressure any value from 90 to 110 kPa, (a) Calculate the mass of the piston if the area of the piston is 0.055 m?

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.

An insulated rigid tank is divided into two compartments of different volumes. Initially, each compartment contains the same ideal gas at identical pressure but at different temperatures and masses.
* Your answer is incorrect. Water contained in a piston-cylinder assembly, initially at 300°F, a quality of 80%, and a volume of 6 ft3, is heated at constant temperature to saturated vapor. If the rate of heat transfer is 0.3 Btu/s, determine the time, in min, for this process of the water to occur. Kinetic and potential energy effects are negligible. At = i 5.217 min
