Asking questions about centrifugal pump power calculation
Thread Content
Dear experts, the simplified formula for calculating the centrifugal pump shaft power is S=0.163x liquid density
Can you list the formula for calculating shaft power?
You need to specify the units of all your parameters. For example, the flow rate is m3/s, m3/h, l/min, gpm.
Tips from the Design Institute: There is something wrong with the formula you wrote, P (w) = density (kg/m3) * g (gravitational acceleration 9.8) * H (lift m) * Q (m3/min)/efficiency/60 Your 0.163 is obtained by 9.8/60. Note that the flow unit of your formula is m3/min. Don’t make a mistake.

Using the chemical calculation APP, you can easily calculate the power of the centrifugal pump. See details: https://bbs.hcbbs.com/thread-2693876-1-1.html
The unit conversion is actually the acceleration of gravity g
