For Measuring The Flow Rate From The Holding Tank It Was Decided To Attach A Venturi Meter In The Outlet Pipe The Vent 1 (92.71 KiB) Viewed 21 times

For measuring the flow rate from the holding tank, it was decided to attach a venturi meter in the outlet pipe. The venturi meter throat diameter d = 25 cm, and pipe diameter D = 40 cm, and the head loss from the venturi meter to the end of the pipe is h = 0.9V2/29, where V is the velocity in the pipe. Neglecting all other head losses, determine what head H and discharge Q will initiate cavitation if the atmospheric pressure is 100 kPa abs and pv at 20°C = 2.34 KPa abs. Assume a = 1.0 at all locations. d H Water T = 20°C O Q = 0.815 m3/s H = 4.08 m O Q = 0.805 m/s H = 4.0 m Q = 0.825 m3/s H = 4.15 m O None of them correct
