Formation of Cavitation
Explain the reason behind formation of the Cavitation in the Centrifugal Pump and not in the Displacement Pump?
Expert
Formation of the cavities or the bubbles is invoked by the flow separation, or non-uniform flow velocities, inside the pump casing. In the centrifugal pumps, eye of pump impeller is smaller in comparison to the flow area of pipe. This decrease in the flow area of pump causes the increase in flow rate. So the pressure drops occurred between pump suction and vanes of the impeller. Air bubbles or the cavities are formed due to the liquid vapour because of the increase in the temperature in impeller. This air bubbles are transmitted to the pump that forms the cavitation.
Water flows at 40 m/s from the jet of area of cross-section of 0.008 m2 on to a flat plate as shown in the figure. Determine the force F normal to the plate, and also the flow rates out of the plate. Q : Causes and consequences of dynamic Discuss the causes and consequences of dynamic loading on structures based on two real examples. Support your discussion with proper diagrams or sketches. Your discussion shall include the time and location of the event, type and source of dynamic loa

Difference between PLC and Logic Card: There is technically no difference. Both are logic controller utilized for several applications and in PLC has it's own internal memory (compared to Logic card).
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
