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
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...

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,...
Thermodynamics: Vertical shaft, piston and a gas, Determine heat transfer
Figure P2.70 shows a gas contained in a vertical piston-cylinder assembly. A vertical shaft whose cross-sectional area is 0.8 cm2 is attached to the top of the piston. The total mass of the piston and shaft is 25 kg. while the gas is slowly heated, the internal energy of the gas increases by 0.1 kJ, the potential energy of the piston-shaft combination increases by 0.2 kJ, and a force of 1334 N is exerted on the shaft as shown in...

1. A 0.550 kg metal cylinder is placed inside the top of a plastic tube, the lower end of which is sealed off by an adjustable plunger. The cylinder comes to rest some distance above the plunger. The plastic tube has an inner radius of 6.39 mm and is frictionless. Neither the plunger nor the metal cylinder allow any air to flow around them. If the plunger is suddenly pushed upwards, increasing the pressure between the plunger and the metal...

A piston/cylinder arrangement with an cross sectional area of 1 mạ contains carbon dioxide at 200 kPa and 290 K. The cylinder has a thick piston that initially held by a pin as shown in Figure 1. The metal piston has a density of 8000 kg/mº, standard acceleration of gravity, &c is 9.81 m/s and the atmospheric pressure is 101 kPa. The pin is now removed, allowing the piston to move and after a while the gas returns to 290...
