What is the formula to calculate Power(Kw) and Rpm of a hydraulic rotator (Vane model) from Torque 900 Nm, Displacement 330cm3, flow rate 14 L/min, volumetric efficiency is 0.9?
@EngDesServices
Hello Friend,
Thank you so much for your kind reply.
But I see some faults in the formula when tested with my model.
When I tested the rotator with flow of 14l/min, RPM was 42.
So Power (KW)= (900*41)/9.548
= 3864.68 KW
= 5178.67 HP.
I think the constant should be 9554 instead of 9.548?
@hydtools,
Hello Friend,
I understand the concept behind 9.9453
But look the answer 3864.68 KW.
I am sure this power is not technically possible.
Please correct me if I am wrong
