1. A pipe of diameter 1.1 ft narrows to a diameter of 0.8 ft. Air moves through the pipe at a mass flow rate of 6.1 slugs/sec. Recall 1 slug = 32.2 lbm. If at the larger diameter a pressure of 110 psig and a temperature of 75 °F exist, compute the pressure, velocity, density and temperature in the smaller cross-section. Ans. T₂ = 38 F, P2 = 98 psia, p2 = 0.0165 slugs/ft^3, V₂ = 735 ft/sec
