I am trying to calculate the "downward force" of an impeller. Is this the same a hydraulic force? (e.g. (19,000 x horsepower x service factor)/(rpm x impeller diameter).
Have an insight or suggestion?

Re: Calculate "downward force" on an impeller
25 September 2007 at 1:29pmThe axial force on an impeller can be calculated from the horizontal force [lbs] = torque (63025 x horsepower/rpm) divided by 85% of the impeller diameter [inches] (typical equivalent load point on the blade). Then, resolving the horizontal force to the axial direction by dividing by the tangent of the blade angle with respect to the horizontal.
