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
GOOD ONE FOR FRESHERS
Best learning app
Sir it would be a great help if you provide us the necessary resources like ISHRAE Handbook etc. Thank you.
Just want to say....Thank you soo much
HAP software,Uski official website se, INDIA region ka trial nahi mil pa raha hai........kya karen?
Thank you so much sir
Very helpful who are going to come in HVAC field.

Sir, ye baar baar " Thik hai, Thik hai " bolte ho na , ye bahot irritating lagta hai . 1 minute me ek baar " thik hai" bolenge to chalega.
