An air roamer contains 10 kg of air at 7 bar. A blow-off valve is opened in error and closed again within seconds, but the pressure is observed to drop to 6 bar. Calculate the mass of air which has escaped from the receiver, stating dearly any assumptions made. Calculate also the pressure of the air in the receiver some time after the valve has been dosed such that the air temperature has attained Its original
