A 0.25 to 0.30 head rise to shut-off ratio is a reasonable value for centrifugal pump calculations. dr rachel harrison cardiothoracic surgery

"WebThe pump is working, but the force of gravity causes the water’s rise in the vertical discharge pipe to stop and the net flow stops. This is known as the “shut-off head”, it’s the amount of head a pump can produce at zero flow. To choose your required pump, you need to know two things: the total head and what flow rate you require. " - How to calculate head rise
