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)
