## relation between discharge and head of centrifugal pump

Centrifugal pumps Features of the centrifugal pumpDepending on the required delivery head, the centrifugal pump will find its operat-ing point when the plant curve and pump curve meet. The flow rate rises from Q 1 to Q 2. Features of the centrifugal pump Q/H curve Centrifugal pumps ...Pump Head Calculation - Pump Performance CalculationIn fluids dynamics the term pump head is used to measure the kinetic energy which a pump creates. Head is a measurement of the height of the incompressible fluid column the pump could create from the kinetic energy, that the pump gives to the liquid. The head and flow rate determine the performance of a pump, which is graphically shown in the figure as the performance curve or pump ...

Including head, power and efficiency were shown graphically. The relation between the volumetric flow rate and the head within two previous conditions is shown in Fig. 3 .

### FLUID MECHANICS TUTORIAL No.8B CENTRIFUGAL PUMPS

WORKED EXAMPLE No. 1 A centrifugal pump is required to produce a flow of water at a rate of 0.0160 m3/s against a total head of 30.5 m. The operating characteristic of a pump at a speed of 1430 rev/min and a rotor diameter of 125 mm is as follows. EfficiencyRelationship between pump total head and discharge pressureThe discharge pressure of a pump is not the same as the value in which the total head shown in the performance curve of the pump is converted into pressure. 1 . Abbreviation H . Total head (m) Hd Discharge head referred to pump shaft center (m) Hs : Suction headCentrifugal Pump | Efficiency Of A Centrifugal Pump | .EFFICIENCY OF A CENTRIFUGAL PUMP Efficiency of a centrifugal pump is three types. 1) Manometric efficiency ( η man) 2) Mechanical efficiency ( η m) 3) Overall efficiency ( η o) In a centrifugal pump, Power is transmitted from the shaft of the electric motor to the shaft of the pump and then to the Impeller and from the Impeller the power is given to the water.Centrifugal Pump Specific Speed | Pumps & SystemsA reaction turbine is, basically, just a centrifugal pump running backwards, with the fluid being pushed backwards through it. If it's a double-suction impeller, do not divide by 2. With suction specific speed, we divide the capacity by 2, but not for (discharge) specific speed.Flow rate [m h] Total head [m] - FristamThe power consumption is the total energy transferred by the pump to the discharge flow. Flow rate [m≈/h] Total head [m] Power consumption Pump technology terms Looking at two parallel plates with the surface A and the distance y, displaced against each ...
