Homework 6
-Problem II –
A volume of compressed air storage tank is 0.3m3, and the air
pressure P1 in the tank is 1MPA. When a part of compressed air is
used, the pressure P2 of the air in the tank decreases to 0.9 MPa. Set
the room temperature at 20 °C, calculate the mass of original air m1
and the mass of residual air m2. Air gas constant Rg = 287.1 J /
(kg · K)).
