N = RPM of pump n = Rev/sec of Pump Q = Flow rate in m 3 /sec H = Head in meters g = Gravitational constant 9.81 m/sec 2 British Units Nq = Where N = RPM of pump Q = Flow rate in Gallons per minute GPM H = Head in feet Note: 1. For multistage 2.
4. Volumetric Flow Rate The volumetric flow rate Q - ft³/s can be calculated as the product of the cross sectional area A - ft² for flow and the average flow velocity v – ft/s . Q = A x v Example 6: A pipe with an inner diameter of 4 inches contains water that.
The head and flow rate determine the performance of a pump which is graphically shown in the figure as the performance curve or pump characteristic curve. The main reason for using head instead of pressure to determine the performance of a centrifugal pump is that the height of the fluid column is not dependent on the specific gravity weight of the liquid while the pressure from a pump
This calculator can be used to determine the centrifugal pump brake horsepower BHP for a given flow rate Q head H specific gravity S.G. and efficiency Eff . If you enter any four of these variables as inputs the calculator will determine the fifth variable.
A centrifugal pump aids in transporting fluids by conversion of rotational energy often from a motor to energy in a moving fluid. Calcuate minimum rate of fluid flow in a centrifugal pump using this online Centrifugal Pump Minimum Flow Rate Calculator based on specific heat capacity specific gravity of the fluid and power input.

Pump Curve Speed Calculator This centrifugal pump curve calculator is meant to quickly calculate the different operating conditions when a centrifugal pump is sped up or slowed down. Using affinity laws we can accurately calculate the pressure flow and required
In series arrangement each pump handles same flow rate but the total head produced by the combination of pumps will be additive. Since each pump generates a head H corresponding to a flow Q when connected in series the total head developed is Ht = H1 H2 where H1 H2 are the heads developed by the pump in series at the common flow rate Q.

This flow rate calculator uses flow velocity and cross-sectional flow area data to determine the volumetric flow rate of liquid. You can calculate the flow rate in five simple steps: Select the shape of the cross-section of the channel Input all the measurements required
Hydraulic Pump Power The ideal hydraulic power to drive a pump depends on the mass flow rate the liquid density the differential height - either it is the static lift from one height to an other or the total head loss component of the system - and can be calculated like
Sections: Pump Spreadsheets and Calculations Pumped Water Systems Keywords: mechanised pumps spreadsheet water pumps This spreadsheet allows the user to find the pump power requirement Watts or Brake Horse Power for various feeder pipe diameters in and given a known flow rate LPS pipe length m and head m and then select a suitable pump based upon available pump characteristic data.
A pump curve denotes flow on the x-axis horizontal and head pressure on the y-axis vertical .The curve begins at the point of zero flow or shutoff head and gradually descends until it reaches the pump runout point or maximum flow rate. The pump’s operating

Pump Flow This calculator page enables you to calculate either the Flow Rate Q litres/minute or Volumetric Displacement Vg cm3 . In order to calculate the hydraulic Pump Flow rate Q l/min you must enter the following figure Pump Speed n for AC Motors this
Centrifugal pumps are used to induce flow or raise the pressure of a liquid. The minimum flow rate of a liquid is how much liquid passes through an area in a given time. The flow rate is usually represented by the symbol Q. Calculate the Minimum Rate of fluid flow in a Centrifugal Pump using this online calculator.
