A horizontal 154 mm diameter pipe gradually reduces its section to 53 diameter, subsequently enlarging into 154 mm section. The pressure in the 154-mm pipe at a point just before entering the reducing section is 141 kPa and in the 53 mm section at the end of the reducer, the pressure is 73 kPa. If 627 mm of head is lost between the points where the pressure are known compute the rate of flow in L/s of water through the pipe.
5. Oil of specific gravity 0.750 is pumped from a tank over a hill through a 24′′ pipe with the pressure at
the top of the hill maintained at 25.5 psi. The summit is 250 ft above the surface of the oil in the tank,
and oil is pumped at the rate of 22.0 cfs. If the lost head from tank to summit is 15.7 ft, what
horsepower must the pump supply to the liquid? indicate free body diagram
