Place the pump into the bucket so that it can reach the bottom. Start the pump at the same time you start the stop watch to remove the water from the bucket. Stop the timer when the bucket is empty. Write down
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...
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=...
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.
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 ...
In this section, methods to calculate mass flow rate and boost pressure required to meet a horsepower target are presented. This data will then be used to choose the appropriate compressor and turbocharger. Having a horsepower target in mind is a vital part of the process. In addition to bei...
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 horsepower depending on drivetrain. Horsepower and engine d...
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...
