Apple juice is being pumped at 30 C from an open tank through a sanitary pipe with an inside diameter of 25 mm to a second tank at a higher level. The mass flow rate is 1 kg/s through a 27 m of straight pipe with two 90 standard elbows and one angle valve. The supply tank maintains a liquid level of 2 m, and the apple juice leaves the system at an elevation of 10 m above the floor. Determine the power requirements of the pump if the friction factor, product viscosity and product density are 0.006, 0.0021 Pa s and 0.997 g/cm3, respectively.
