A 12′′ pipe line carries oil of specific gravity 0.811 at a velocity of 80.0 ft/sec. At points A and B, measurements of pressure and elevation were 52.6 psi and 100.0 ft and 42.0 psi and 110.0 ft,respectively. For steady flow, find the lost head between A and B.

A horizontal 300-mm pipe contracts to a 150-mm diameter. If the flow is 0.127 m3/s of oil (s.g.=0.88) and the pressure in the smaller pipe is 265 kPa what force is exerted on the contraction, neglecting friction?
A pipe, 12 inch in diameter at A, discharges 4.0 cfs of heavy fuel oil (sp gr = 0.899) into the air at B, where the diameter is 6 inch. If B is 12 ft above A and the frictional loss between the two points is equivalent to 3.0 lb per sq in, determine the pressure at A in pounds per square inch.
