How do I calculate head pressure in a pump?

A pressure head is the height of the free surface above a liquid at rest.The Pressure head formula can be expressed.

It is convenient to express fluid pressure in terms of pressure head since the pressure at any point in a liquid depends on the height of the free surface above the point.The pressure is expressed in meters of a liquid column.

A relationship between the heights of columns of different liquid can be obtained by using P.If h1 and h2 are the heights of the column of liquid of specific weight, then the same pressure needs to be developed at any point.

If S1 and S2 are the specific gravity of the two liquids and W is the weight of water, then the sinB equation should be written.

If h1 and h2 are the depth of two points below the free surface in a static mass of liquid of specific weight W and P1, the pressure difference between these points is obtained.

The difference in pressure at any two points in a static mass of liquid is dependent on the depth and elevation of those points.
