A piston-cylinder assembly contains 0.5 kg of water. Initially, the piston is resting against the stops when the water pressure and temperature are 1.00 bar and 125 degrees celsius, respectively. The piston has a mass of 50 kg and face area of 0.01 m^2; local atmospheric pressure is 1.01 bar; local gravitational acceleration is 9.81 m/s^2. 1. What water pressure would be required to lift the piston from the stops? 2. If the initial specific internal energy is 2544.86 kJ/kg,...

Air contained within a vertical piston-cylinder assembly is shown in Figure 1. On its top, the 10-kg piston is attached to a spring and exposed to an atmospheric pressure of 1 bar. Initially, the bottom of the piston is at x = 0, and the spring exerts a negligible force on the piston. The valve is opened and air enters the cylinder from the supply line, causing the volume of the air within the cylinder...

Air is contained in a vertical piston-cylinder assembly such that the piston is in static equilibrium The atmosphere exerts a pressure of 101 kPa on top of the 0.8 meter-diameter piston. The gage pressure of the air inside the cylinder is 1.2 kPa. Subsequently, a weight is placed on top of the piston, as shown below, causing the piston to descend until reaching a new static equilibrium position. At this position, the gage pressure of the air inside the cylinder is...
