As shown in the figure, the water flows from the ground floor of a three-storey house to the second floor through pipes of 20 mm diameter (average roughness of the pipe material = 0.0015 mm) at a volumetric flow rate of 0.75 L / s. Water is discharged from the system to atmospheric pressure through a tap with a 12 mm diameter outlet. There are 4 winged elbows, one ball valve and one faucet throughout the installation. Calculate the effective pressure at point 1. (pwater=998 kg/m3, uwater=1.12x10-3 Pa s, g=9.81 m/s2)

QUESTION 2 Discharge occurs through a vertical pipe of a single-acting piston pump that is 2 m in length, 50 mm in diameter, and is fitted with an air chamber. The piston has a diameter of 150 mm and a stroke length of 300 mm. The pump is 1.9 m above the water level in the sump. Assume the atmospheric pressure to be 10.3 m of water, Fanning friction factor of 0.007, and the speed of the pump is 50 rpm. Determine the flow rate into or out of the air chamber when the crank makes an angle of 10°, 110°, and 170° with the inner dead center.
