1. Calculate Motor Pump Size

CALCULATE MOTOR PUMP SIZE

• Calculate Size of Pump having following Details * Static Suction Head(h2)=0 Meter * Static Discharge Head (h1)=50 Meter. * Required Amount of Water (Q1)=300 Liter/Min. * Density of Liquid (D) =1000 Kg/M3 * Pump Efficiency (pe)=80% * Motor Efficiency(me)= 90% * Friction Losses in Pipes (f)=30%

CALCULATIONS:

• Flow Rate (Q) =Q1x1.66/100000 =300×1.66/100000= 0.005 M3/Sec * Actual Total Head (After Friction Losses) (H) = (h1+h2)+((h1+h2)xf) * Actual Total Head (After Friction Losses) (H)=50+(50×30%)= 65 Meter. * Pump Hydraulic Power (ph) = (D x Q x H x9.87)/1000 * Pump Hydraulic Power (ph) = (1000 x 0.005 x 65 x9.87)/1000 =3KW * Motor/ Pump Shaft Power (ps)= ph / pe = 3 / 80% = 4KW * Required Motor Size: ps / me =4 / 90% = 4.5 KW

• REQUIRED SIZE OF MOTOR PUMP = 4.5 HP OR 6 HP
