How to Convert Units of Acceleration. Conversions are performed by using a conversion factor. By knowing the conversion factor, converting between units can become a simple multiplication problem: S * C = E. Where S is our starting value, C is our conversion factor, and E is our end converted result. To simply convert from any unit into grams, for example, from 5 kilograms, just multiply by the conversion value in the right column in the table below. 5 kg * 1000 [ (g) / (kg) ] = 5000 g. To convert from g into units in the left column divide by the value in the right column or, multiply by the reciprocal, 1/x.
There are several terms associated with the pump characteristic curve that must be defined. Shutoff head is the maximum head that can be developed by a centrifugal pump operating at a set speed. Pump runout is the maximum flow that can be developed by a centrifugal pump without damaging the pump.
Pump Cavitation Definition. Pump cavitation is the formation and subsequent collapse or implosion of vapor bubbles in a pump. It occurs when the absolute pressure on the liquid falls below the liquidâs vapor pressure.When the vapor bubbles collapse with high enough frequency, it sounds like marbles and rocks are moving through the pump.nsufficient NPSH leads to lower liquid pressure in the pump and if pressure in the eye of the impeller falls below the vapor pressure of the fluid, then cavitation can begin by formation of vapor bubbles.
