Water flows at a rate of 9 L/s in a horizontal stainless-steel pipe with 5 cm diameter, whose length is 30 meter. Calculate: (a)the pressure drop, (b)the head loss, and (c) the pumping power requirement to overcome this pressure drop. Assumptions: 1. Steady flow and fully-developed. 2. There are no components. 3. No pumps and turbines. 4. Absolute roughness of stainless steel is 2x10-6 m. 5. Pwater = 999.1 kg/m, water = 1.138x10- kg/m.s, 6. 1 m = 1000 L, 1 kN = 1000 kg/m.s, 1 kPa = 1 kN/m, 1 kW = 1 kPa.m/s Water flows at a rate of 9 L/s in a horizontal stainless-steel pipe with 5 cm diameter, whose length is 30 meter.
