Mar 29, 20190183;32;Look up the specific gravity of the fluid. Specific gravity is a measurement of density the more dense a fluid is, the more power it takes to pump. Water has a specific gravity of 1. If pumping a different fluid, look it up on a specific gravity engineering table. This example will use water, so the specific gravity is 1.

Aug 05, 20140183;32;Where does the 2.31 come from? Divide 33.9 feet of head by 14.7 psia. Water has a specific gravity of 1.0. So the formula always works. If the specific gravity is known for the fluid that is being pumped, pressure gauge readings can be converted to Head in Feet, which is useful for determining where the centrifugal pump is operating on its pump curve.

Jan 23, 20180183;32;Pump lift is the linear vertical measurement that indicates the distance a certain pump can draw a liquid from the intake into the pump body. It is then exposed to the moving parts which will compress the liquid and eject it through the outlet side of the pump.

Jan 27, 20090183;32;Pump suction and discharge heads stay do not vary with specific gravity or density of products. The pressures change. Which is why it is much more convenient to work with NPSHeads, rather than NPSEquivalent Pressure, especially when you might have multiple products running through the system. Head mesures energy, psi measures force.

Kinds and units of measurement. Both gas and liquid flow can be measured in physical quantities of kind volumetric or mass flow rates, with units such as liters per second or kilograms per second, respectively. These measurements are related by the material's density.The density of a

Just as it is possible to utilize the square root of time model to inject liquid volatile agents in a closed circle, 1 it is possible to deliver a total intravenous (IV) anesthesia by intermittent bolus. While such pedagogical exercises may be extended to clinical scenarios, most practitioners opt for

May 08, 20140183;32;As it is a ratio, specific gravity is unitless. A fluid with a specific gravity of less than 1 would be considered lighter than water, while a fluid with a specific gravity greater than one would be considered heavier than water. So how do specific gravity and density affect pump sizing and selection? Let us explain.

Let us first consider the very simple situation where the fluid is staticthat is, v 1 = v 2 = 0. Bernoullis equation in that case is. P 1 + gh 1 = P 2 + gh 2.. We can further simplify the equation by taking h 2 = 0 (we can always choose some height to be zero, just as we often have done for other situations involving the gravitational force, and take all other heights to be

Tell me more about density. Different liquids may have different densities (or weights, measured in g/cm3 or kg/m3) and the density of a single type of fluid does vary with temperature. When we are sizing pumps, we pay particular attention to the head, or how many metres up in the air we can pump a given fluid at one bar of pressure.

When selecting pumps, the flow rate or rated capacity of the pump must be matched to the flow rate required by the application or system. Pressure is a measure of resistance the force per unit area of resistance in the system. The pressure rating of a pump defines how much resistance it can handle or overcome.
