A vacuum pump has a cylinder of volume (v) and it is connected to a vessel of Volume (V) to pump out air from the vessel. The initial pressure in the vessel is P. calculate the reduced pressure after:
a) first stroke
b) second stroke
c) n stroke
what number of stroke is needed to reduce the pressure from 2 ×10^5 Pascal to 1×10^3 Pascal if the closed vessel has a volume of 200cm³ and the pump cylinder has a volume of 20cm³?
