Water flows from the ground floor to the second floor of a three-story house as shown in the figure above. With a volume flow rate of 0.75 L / s, passing through 20 mm diameter pipes (average of pipe material roughness = 0.0015 mm) flows. The water is a tap with a 12mm diameter outlet from the system is evacuated to atmospheric pressure by means of. 4 winged elbows throughout the installation, one There is a ball valve and a tap. Calculate the effective pressure at point 1.

(pwater = 998 kg / m3 , uwater = 1.12x10-3 Pa s, g = 9.81 m / s2 )
