Friction loss in pumping oil to pressurized tankan oil having a density of 833 kg/m3and a viscosity of 3.3 x 10³ Ns/m² is pumped form an open tank to a pressurized tank held at 345kPa (gage). The oil is pumped from an inlet at the side of the open tank through a line ofcommercial steel pipe 3-inch nominal pipe size r of internal diameter 77.92 mm at the rate of3.494 x 10³ m³/s. The length of straight pipe is 122m and the pipe contains two elbows (90") anda globe valve half open. The level of the liquid in the open tank is 20 m above the liquid level inthe pressurized tank.

In a hydraulic press, the ram has a diameter of 20 cm and the plunger 2 cm. The fluid is an oil of specific gravity 0.8. Calculate the mass that can be raised by placing a mass of 100 kg on the plunger: (i)When the plunger and the ram are on the same horizontal plane, and (ii)When the liquid level in the plunger is 0.5 m above that in the ram. What is the mechanical advantage of the press in cases (i) and (ii) above?
Oil with specific gravity of 0.88 flows through a pipe which changes from 6 in. at section A to 18 in. at section B.
