WebThe Head By dividing each term with the specific weight - γ = ρ g - equation (1) can be transformed to express head as p / γ + v2 / 2 g + h = constant along a streamline = H (2) where H = the total head (m fluid column) … WebCharacterizing the minor losses involves one of two methods. The first method, known as the equivalent length method, equates the head loss of the valve/fittings to a length of pipe that would cause equivalent friction losses. The other method uses the resistance coefficient or minor loss coefficient to estimate the head loss.

Webthe same as any of the three types of head. A separate head loss coefficient, k, can be determined for every element leading to minor losses. K is a dimensionless parameter to help determine head loss. The coefficient is then multiplied by the velocity head to get the head loss as shown below in Equation-1: * A = @ . K O O = * A = @ .
