When the pipe length and flow rate are known, the pipe diameter can be calculated for a particular pressure drop. 2g = 0,0225 500 0.2 6,42 29,81 = 117 m hf = f L d v2 2g = 0,0225 500 0.2 6,42 29,81 = 117 m The head loss for an inclined pipe is hf = p g +z1 z2 = p g +Lsin10o. As a result, p = g(hf 500sin 10o) = 9009,81(11787) = 265103 is the pressure drop.
Calculate the flow rate. Determine the flow rate before sizing and selecting a centrifugal pump.
Calculate the static head.
The friction head should be determined.
Calculate the total number of HEAD Choose a pump.
TO CHOOSE A PUMP WE NEED TO KNOW 2 BASIC VALUES: FLOWRATE AND LIFT PRESSURE OR HEIGHT (OR HEAD) A: area of the pipe π x (d/2)2 [m2] v: speed of liquid (water) in the pipe [m/s] Q:

You must know four things before you can choose a pump that will meet your needs: 1) the total head or pressure it must operate against, 2) the intended flow rate, 3) the suction lift, and 4) the fluid properties
