A rigid tank primarily contains 3 kg of air at 500 kPa, 290 K. The tank is connected by a valve to a piston-cylinder assembly oriented vertically and consisting of 0.05 m³ of air initially at 200 kPa, 290 K. Even though the valve is closed, a slow leak permits air to flow into the cylinder until the tank pressure falls to 200 kPa. The weight of the piston and the pressure of the atmosphere keep a constant pressure of 200 kPa in the cylinder; and owing to heat transfer, the temperature stays constant at 290 K. For the air, calculate the total amount of energy transfer by heat, in kJ. Assume ideal gas behavior.
Given the properties in the table below a. Plot the engineering stress-strain curves for the 3 materials. You can assume the materials behave linearly when they plastically
"The pressure of a needed mass of gas at constant volume differs directly as its Kelvin Temperature",
The water level in a tank is 20 m above the ground. A hose is connected to the bottom of the tank, and the nozzle at the end of the hose is pointed straight up. The tank is at sea
It is the force that the field would exert on any unit magnetic pole placed in the field. It is also known as magnetic force.
