Pump force calculation
Pump force calculation
(OP)
Good morning All,
I have a pump with a total head of 19.4m (63'-7") and a flow rate of 1571 litres/second (24901 GPM)
The pump discharge flange is 700mm and there is a reducer to increase the size to match the riser pipeline of 800mm diameter.
The max rotational speed of the pump is 750 RPM.
What is the calculation or formula to determine the forces on the pump?
Regards
John

Seriously, what forces? Short circuit torque, fluid pressure, pipe thermal loads?

Thermal loads are very low, but it was the fluid pressure I was thinking of. I have read a few posts on this forum and it seems there are no forces to worry about.
The discharge pipe (800mm diameter) has a horizontal length of approx 8 metres and then a 'duckffoot' bend to turn the pipe up to a 12m high chamber. I calculated the load on the bend in the conventional way but wondered if there was any kind of back-pressure on the pump.
