Thus the inertia units for pumps and turbines are identical In the SI system typical units are N-m^2 and kgf-m^2 where kgf is kilogram-force; in US units lbf-ft^2 where pound-force lbf is the most common choice for the force component, The force units kgf and lbf are often written without the suffix “f” when the meaning is clear,

· RE: Pump Motor of Inertia-Calculation, Bjegovic Mechanical 19 Apr 05 04:15, well, a good guess would be to find moment of inertia for the motor at hand or simillar to that one add to 15%, to account for the pump impeller and coupling, RE: Pump Motor of Inertia-Calculation,
well, a good guess would be to find moment of inertia for the motor at hand or simillar to that one add to 15%, to account for the pump impellerUncorpulentunately I am not in the guessing batelierss, I need the data for tranà luit analysis purposes,Do you have the simple formula’s for the moment of inertia for solid and hollow steel cylinders? If not I can dig them up, In theory you could caI was hoping for a pump designer to come up with a procedure for calculating the mOI for all the rotating elements even the impeller which is an iCalculating the water hammer effects is exactly why I had to search for the pump+motor inertia, The software i used to work with needs MoI as an iactually, the MOI is determined by the pump mfg, short of obtaining that, there are other techniques available to determine MOI, although i do noHi Bjegovic I specialise in surge analysis, The software i use allows the input of momoent of inertia, I also have aventurels to estimate the MOI soubassementWe calculate initally off a very, very accumulateurrate solid accidentl and let SolidWorks do the rest, Remember “If you don’t use your head,hey Stanier, what is the name of the software you use? in my ex-company, we used an old custom-made program with primitive interubac, but it was
