Find the pressure of air in a vessel being evacuated as a function of evacuation time `t`. The vessel volume is `V`, the initial pressure is `p_0`. The process is assumed to be isothermal, and the evacuation rate equal to `C` and independent of pressure.
The evatuation rate is the gas volume being evacuated per unit time, with that volume being measured under the gas pressure attained by that moment.

A vessel of volume V is evacuated by means of a piston air pump. One piston stroke captures the volume v_0 . The pressure in the vessel is to be reduced to (1/n) of its original pressure , P_0 . If the process is assumed to be isothermal and air is considered an ideal gas, the number of strokes needed in the process is

A chamber of volume V is evacuated by a pump whose evacuation rate equals C. How soon will the pressure in the chamber decrease by eta(eta gt1) ?

A vessel of volume V is evacuated by means of a piston air pump. One piston stroke captures the volume Delta V . How many strokes are needed to reduce the pressure in the vessel eta times ? The process is assumed to be isothermal, and the gas ideal.

A vessel of volume V is evacuated by means of a piston air pump. One piston stroke captures the volume Delta V . How many strokes are needed to reduce the pressure in the vessel eta times ? The process is assumed to be isothermal, and the gas ideal.

Why is a cathode ray tube evacuated to a low pressure ?

A vessel of volume V is evacuated by means of a piston air pump Upon cach double stroke a piston pump sucks in a volume V of air and expels it. The process is assumed to be isothermal, and the gas is ideal. When this pump is used to evacuate the air from a vessel with a volume V, it performs n double strokes. The initial pressure inside the vessel is p_0 which is equal to the atmospheric pressure. (a) Calculate the final pressure inside the vessel.

A vessel containing 5 litres of a gas at 0.8 m pressure is connected to an evacuated vessel of volume 3 litres. The resultant pressure inside with be (assuming whole system to be isolated)

Vapor is injected at a uniform rate in a closed vessel which was initially evacuated. The pressure in the vessel

Vapor is injected at a uniform rate in a closed vessel which was initially evacuated. The pressure in the vessel

Diatomic gas at pressure 'P' and volume 'V' is compressed adiabatically to 1/32 times the original volume . Then the final pressure is
