A cylinder is fitted with a piston, beneath which is a spring, as in the drawing. The cylinder is open to the air at the top. Friction is absent. The spring constant of the spring is 3800 N/m. The piston has a negligible mass and a radius of 0.018 m. (a) When the air beneath the piston is completely pumped out, how much doe cause the spring to compress? (b) How much work does the atmospheric pressure do in compressing...
A cylinder is fitted with a piston beneath which is a spring as in the drawing.... Your answer is partially correct. Try again. A cylinder is fitted with a piston, beneath which is a spring, as in the drawing. The cylinder is open to the air at the top. Friction is absent. The spring constant of the spring is 3400 N/m. The piston has a negligible mass and a radius of 0.019 m. (a) When the air beneath the piston...
A cylinder is fitted with a piston, beneath which is a spring, as in the drawing. The cylinder is open to the air at the top. Friction is absent. The spring constant of the spring is 4600 N/m. The piston has a negligible mass and a radius of 0.020 m. (a) When the air beneath the piston is completely pumped out, how much does the atmospheric pressure cause the spring to compress? (b) How much work does the atmospheric pressure...
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 closed cylinder of 0.25 m diameter is fitted with a light frictionless piston The piston is retained in position by a catch in the cylinder wall and the volume on one side of the piston force of 120 N on the Example 2.5 contains air at pressure of 750 kN/m2. The volume on the other side of piston is ev spring is mounted coaxially with the cylinder in this evacuated space to give a piston in this position. The...
Question 1 Air is contained in a vertical piston-cylinder assembly fitted with an electrical heater. The atmospheric pressure is 100 kPa and piston has a mass of 50 kg and a face area of 0.1 m . Electric current passes through the heater, and the volume of air slowly increases by 0.045 m. The mass of the air is 0.3 kg and its specific internal energy increases by 42.2 kJ/kg. Assume the assembly (including the piston) is insulated and neglect...
Spring 2018 Calculating work. A gas is enclosed in a cylinder fitted with a light piston that moves without friction. This piston always exerts a constant, atmospheric pressure on the gas so that the pressure within the gas is constant, atmospheric pressure. 4. Sketch a plot of pressure vs. volume in this situation. To do this, you can plot points. What is the pressure of the gas when the volume is 12.0 m? 18.2 m? When 1250 kJ of heat...
Question Two (10 Marks] Air is contained in vertical piston-cylinder assembly fitted with an electrical resistor. The atmosphere exerts a pressure of 1 bar on the top of the piston, which has a mass of 45 kg and a face area of 0.09 m². Electric current passes through the resistor, and the volume of the air slowly increases by 0.45 m while its pressure remains constant. The mass of the air is 0.27 kg. and its specific internal energy increases...
A gas is enclosed in a cylinder fitted with a light frictionless piston and maintained at atmospheric pressure. When 254kcal of heat is added to the gas, the volume is observed to increase slowly from 12.0m3 to 16.2m3 . a. Calculate the work done by the gas. b. Calculate the change in internal energy of the gas.] Express your answer with the appropriate units.
Problem 2: 35 points A cylinder of 5 m height is fitted with a massless piston of negligible thickness and diameter D-Im. Initially, the piston is at the top of the cylinder and 5 kg of boiling water at 100rC existed below the piston. 3000 kg of liquid water at 20C were poured slowly and at a constant rate over the piston to compress the boiling water. Neglect kinetic and potential energy changes a) Find the work done on the...
