Pump Power P(HP)= q(m3/hr)x ρ(kg/m3)x g(m2/s)x h(m)x p(Pa)/ 2685600. Also above pump power is required to lift the liquid to head meters.
System Capacity Planning:Engineers must calculate the required flow rate to meet system demands, such as HVAC systems or water supply networks. Selection of Pump and Components:Accurate flow rate calculation is crucial for selecting the right pump and sizing the piping and other components. Energy E...
When you know your maximum heart rate, you can calculate your heart rate zones and train at the right intensity. Read how to calculate your max HR.
5. Calculate Hp Plug all the predetermined values into the equation for Hp to calculate horsepower. For example, if the system had a pump with a known efficiency of 65 percent and the pump delivers 250 gallons per minute to a total head of 72 feet, the horsepower of the system is: Hp=...
How To Select A Turbo Part 2: CalculationsIn part one of this how to series we explained how to identify target horsepower, why turbos are rated for crank horsepower, and how to calculate wheel horsepower to crank horse...
If you have the individual details of pump base,motor and pump etc you can calculate it. The pump manufacturer might give the centre of gravity for the assembly on some documentation because it might have to be lifted as a complete assembly. Upvote 0 Downvote Not open for further replies...
How to Calculate the Water Inflow Rate = Calculate the Necessary Sump Pump CapacityTypically most of us just buy a 1/4 hp or 1/2 hp sump pump and throw it in the pit and see what happens. But you can guesstimate the rate at which water is flowing into the sump pit by knowing the...
WARNING: Do not use SG values to make treatment decisions, including delivering a bolus, while the pump is in Manual Mode. When the SmartGuard™feature is active and you are no longer in Manual Mode, the pump uses an SG value, when available, to calculate a bolus amount. However, if ...
Water creates pressure or resistance, at predictable rates, so we can calculate pump head as the differential pressure that a pump has to overcome in order to raise the water. Common units are feet of head and pounds per square inch. (A pump characteristic curve calculator might offer ...
How to calculate motor efficiency for variable-speed centrifugal pumps: knowing the efficiencies of the pump, VSD, and motor will enable the engineer to calculate the kW input for a pump, from minimum to maximum flow and head conditions for that pump. Here, the author goes through that ...
