6. A horizontal 150 mm diameter pipe gradually reduces its section to 50 mm diameter,subsequently enlarging into 150 mm section. The pressure in the 150 mm pipe at thepoint just before entering the reducing section is 140 kPa and in the 50 mm section atthe end of the reducer the pressure is 70 kPa. If 600 mm of head is lost between thepoints where the pressures are known, compute the rate of flow of water thru the pipe.

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
