Fluid Mechanich

As shown in the figure above, the water flows from the ground floor of a three-story house to the second floor through pipes of 20 mm diameter (average roughness of the pipe material ɛ = 0.0015 mm) with 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 )
