A 1 m3 volume tank contains air at a constant temperature. If the initial absolute pressure is Po=101.3 kPa, how long will it take for the pressure to fall to a final pressure of 1 Pa? V=1 m3 Po=101.3 kPa To=20 C To vacuum pump Q=0.001 m/s = a) If the air is evacuated at a const. standard vol. flow rate of Osc= 0.001 m3/s, i.e. standard cubic meter per second? (1000 s)
