A water tank filled with solar-heated water at 40°C is to be used for showers in a field using gravity-driven flow. The system includes 36 m of 1.5-cm-diameter galvanized iron piping with four miter bends (90°) without vanes and a wide-open globe valve. If water is to flow at a rate of 1.2 L/s through the shower head, determine how high the water level in the tank must be from the exit level of the shower. Disregard the losses at the entrance and at the shower head, and neglect the effect of the kinetic energy correction factor. The density and dynamic viscosity of water at 40°C are p= 992.1 kg/m3 and u= 0.653 x 10-3 kg/m-s. The roughness of galvanized iron pipe is ɛ = 0.00015 m. The loss coefficient is KL = 0.5 for a sharp-edged entrance, KL = 10 for global valve, and KL = 1.1 for an elbow. The free surface of the tank must be m above the shower exit to ensure water flow at the specified rate.

QUESTION 1 Compute the resulting pressure in kPa after a "real" diffuser in which the energy loss due to sudden enlargement is considered for the flow of water at 25°C from a 36 mm OD x 2.0 mm wall copper tube to an 85 mm OD x 2.5 mm wall copper tube, the pipes are the same elevation. The volume flow rate is 150 L/min and the pressure before the enlargement is 501.448 kPa.
