Positive Displacement Type of Pump
Explain why the Centrifugal Pump is not known as the Positive Displacement Type of Pump?
Expert
Centrifugal has varying flow depending upon the pressure or the head; on the other hand, flow in the Positive Displacement pump is more or less constant regardless of the pressure.
Similarly, the viscosity is constant for the positive displacement pumps whereas, value of the centrifugal pump is up and down because higher viscosity liquids fill the clearances of pump resulting in a higher volumetric efficiency. Whenever there occurs a viscosity change in the supply there occurs greater loss within the system. This means change in the pump flow is affected through the change in pressure.
From Bernoulli's equation we know that presure head + velocity head at inlet and outlet header is same. If so what is ' W' then in the equation ?
The pump illustrated in the figure adds 20 kW of power to the flowing water. The only vital loss is that which takes place across the filter at the inlet of the pump. Find out the head loss for this filter. Note that the gage pressure upstream of the filter is negativ
