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.
A pipe with unequal ends is used to transport a fluid. The pipe diameter at the larger end is 0.81 cm and the other end is 0.28 cm. The larger and smaller ends are located 10 m and 4 m, respectively, from the datum line. If the flow at the 10 m datum line is 1.60 m/s and the pressure is 5244 kN/m2, compute for the pressure, in kPa, at the smaller end. Express your answer in 3 decimal places.
In a venturemeter used for measuring the flow of oil (S = 0.85) through a horizontal pipeline, the pipe diameter is 2.4 times the diameter at the throat. Connections are made from the entrance to the meter and the throat to a vertical U tube containing mercury. If the difference level between the fluids in the U-tube arms is (x +1/S.N ) in cm, where S.N. is student serial number. Neglect friction in the pipe. Find an expression in terms of x for the velocity of the oil in the pipe.
A pipe has an initial radius of r1, which then changes to a radius of r2. The velocity of the water in the initial part of the pipe is v1.

pump with critical cavitation number 0,08 pumps water to a total head of 60 m and temperature of 15°C (Pv=1707 Pa). If the barometric pressure is 98 kPa, head loss in the suction pipe is 1m. Find the maximum value of static suction lift in meters to avoid cavitation in the pump.

At the gasoline transfer facility (ρᵣₑₗ=0,75) from the pond of storage to consumption, you want to install a pump to circulate a flow of 40(lt/s). The 400m long pipe is cast iron 150mm in diameter and consists of a check valve, a gate valve and 2 commercial medium radius elbows. The consumption tank is pressurized to 2,9 (kgf/cm²) gauge pressure.

Sunflower oil (SG = 0.7, viscosity = 154cP) is pumped at a rate of 85 ft^3/min (ID = 3.5in) from large open reservoir to the bottom of another open tank. The liquid level in the reservoir is maintained at 4.5ft, and the bottoms of the reservoir and tank are 17ft apart, vertically. Friction losses in the pipe amount to 7.5% of the elevation head. If 2 hp of power is required for the process, what is the expected liquid level in the receiving tank?
