how we calculate the motor rating of pump for water
suction ?its any formula for that plz give thank u
Answer Posted / naresh
depends on the height of the buidling,depth of he water
coloumn for exmpl 300ft,400ft etc.....,horizontal path of
the water pipe,vertical path i.e height of the building,
after taking these one should calculate the no of satges for
ex 18,20,22 stages, 3ph r single phase power supply,voltage
230v/415v but the actual calculations no idea but these r
the constraints/the details required while selecting the
water pump motor
