Gas flows at a steady rate in a 120 mm diameter pipe that enlarges to a 180mm diameter pipe. At a certain section of the 120mm pipe , the density of gas is 165 Kg/m3 and velocity is 15m/s. At a certain section of the 180mm pipe, the velocity is 10m/s.
(a) What must be the density of gas at the same section?
(b) Solve for unsteady flow
