A piston pump having a barrel of effective volume 100cm3 is used to exhaust a vessel of volume 2.5x(10^3)cm3. If the initial pressure in the vessel is 1 atm, estimate the reduction in pressure produced by two strokes of the pump, assuming that all processes are isothermal and that air behaves as an ideal gas. Further, estimate the numbe of strokes needed to reduce the pressure in the vessel from 1 atm to 0.02 atm.
