Air is flowing at 630 kg/hr through a pipe of 0.05 m diameter and 50 m long. The pipe is made out of Perspex. The entrance gauge pressure is 100 kPa and its density at the entrance is 1.2 kg/m³. It can be assumed that the viscosity remains constant at 18 × 10-6 Pas. If the flow is isentropic (y=1.34) Calculate the pressure at the exit assuming the kinetic head is negligible You may use the following equations: V₂ In c (117) + 6² (+1) in 1 + 4/4] = 0 C C = P₁V₁ + (²) G² V² = P₂V₂ + (VZ 7 ²) G² V ž 2y 2γ
