What is pressure head and kinetic head?

Different heads in Bernoulli’s equation In fluid mechanics, energy per unit weight of fluid is termed as head. Hence it is termed as pressure head. Similarly, the second term represents kinetic energy per unit weight. Hence it is termed as velocity head.

What is the formula of kinetic head?

The kinetic head coefficient can be estimated by the equation (k = 1.66 IO0.413) with r 2 = 0.75 for the OI range from 0.008032 to 0.5649. Part of the dissertation of the first author.

How the kinetic head can be measured?

It is usually measured as a liquid surface elevation, expressed in units of length, at the entrance (or bottom) of a piezometer. In an aquifer, it can be calculated from the depth to water in a piezometric well (a specialized water well), and given information of the piezometer’s elevation and screen depth.

What does potential head mean?

Potential head is the potential energy per unit weight.

What is K in pipes?

The K-value, Resistance Coefficient, Velocity Head, Excess Head or Crane method allows the user to characterise the pressure loss through fittings in a a pipe. The K-value represents the multiple of velocity heads that will be lost by fluid passing through the fitting.

What is gravitational head?

The potential energy per unit weight of fluid due to its elevation above an arbitrary datum.

What is aquifer head?

The head at a particular point in an aquifer is given by the elevation of the point above an arbitrary datum (usually sea level) plus the height to which water will rise in a vertical pipe or well whose lower end is open or screened at the point and whose upper end is open to the atmosphere.

How is velocity head converted to pressure?

in which v is velocity, g is the gravitational acceleration, p is the pressure at the location, ρ is the fluid density, z is the elevation, and c is a constant in a unit of length. The term ½(v2/g) is regularly referred to as the velocity head and has units of the height of the streaming fluid.

What is unit of kinetic head?

The total energy of the fluid particles per unit weight is known as head. Units: The unit of head is meter.
