Good day
I am trying to use a venturi across a centrifugal pump. The pressure at suction side is about 2 bar and the discharge pressure about 6 to 7 bar. This pump supply drippers and the delivery is about 180 cub/h. I need to inject entrainment air into the suction side and try to use a venturi across the high (discharge) and low (suction) pressure sides of the pump.
I get little to no suction on the venturi. I have a throttling valve to play around with the flow through the venturi. The setup have also quite alot of bends.
Can the low suction be the pressure loss on these bends and relative low diameter pipe between the high and low pressure.
Thank you for feedback
