Hello Everybody,

I'm looking for Pump and Piping Engineering book where i can learn Pump Calculations like Pump Sizing, Calculation of Pressure Drop Across pipe bends, Valves etc and Back Pressure Calculations and apply them to real world problems. I am Basically a Mechanical Engineer and I'm new to Pump and Piping Engineering. Please Suggest me good books which is easily understandable and with lot of examples.

Thank You,

Cheers,

Follow simple steps in sizing pipe using proper units:

How to Size a Pump

To lift water through a certain height.

Formulas

Work = Force x Distance

Power = Work Done___
Time in Seconds

1 Gallon of water weighs 8.33 lbs

1 Horse Power = 550 Ftlb/sec

HP (req) = Power___
550 Ftlb/sec

Ex.

Your building is 10 stories tall

You are pumping 3000 gal of water to the top

You want the water to reach the top in 1 minutes time

How much horse power is required to lift the 3000 gal of water to the top?

Height = 10 stories x 10’ per story = 100’

Weight of water = 3000 gal x 8.33 lb = 24990 lbs

Force = 24990 lbs x 100’ = 2,499,000 Ftlbs

Time = 1 min = 60 sec

Power = 2,499,000 = 41,650 Ftlbs/sec
60 sec

HP (req) = 41,650 Ftlbs/sec
550 Ftlbs/sec

HP (req) = 75.72 HP Assuming Service factor of 1.25 HP = 75.72 X 1.25 =94.65 HP

Recommended horse power = 100 for this scenario
