Pump Calculation Formulas. The same way pump power in horsepower formula can be written as pump power p hp q m3 hr x ρ kg m3 x g m2 s x h m x p pa 2685600. M ρ x v replacing with the appropriate terms allows the calculation of direct mass flow rate. 1 poise 100 cp 1 stoke 100 cst flow velocity v fluid velocity m s where. Displaystyle frac 0 18 0 5 a 0 36 hp motor.
Equation for water at 68 fahrenheit. P in watt here. Displaystyle frac 0 18 0 5 a 0 36 hp motor. Q π r v q π x 0 16 ft x 14 ft s 1 22 ft s 5. Q flow rate in m 3 hr. P in kw here.
Q π r v q π x 0 16 ft x 14 ft s 1 22 ft s 5.
Calculate the volumetric flow rate of water in the pipe. 1 m3 h of water is pumped a head of 10 m. Hence the pump power calculation formula can be written as below pump power p kw q m3 hr x ρ kg m3 x g m2 s x h m x p pa 3600000. Q flow rate in m 3 sec. Q π r v q π x 0 16 ft x 14 ft s 1 22 ft s 5. The theoretical pump power can be calculated as ph kw 1 m3 h 1000 kg m3 9 81 m s2 10 m 3 6 106 0 027 kw.
