Coefficient of Velocity given Head Loss Solution

STEP 0: Pre-Calculation Summary

Formula Used

Coefficient of Velocity = sqrt(1-(Head Loss/Head of the Liquid))
C_v = sqrt(1-(h_f/H))
This formula uses 1 Functions, 3 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Coefficient of Velocity - The Coefficient of Velocity is the ratio of actual velocity to theoretical velocity.
Head Loss - (Measured in Meter) - Head Loss is a measure of the reduction in the total head (sum of elevation head, velocity head and pressure head) of the fluid as it moves through a fluid system.
Head of the Liquid - (Measured in Meter) - The Head of the liquid is the height of a liquid column that corresponds to a particular pressure exerted by the liquid column from the base of its container.

STEP 1: Convert Input(s) to Base Unit

Head Loss: 1.2 Meter --> 1.2 Meter No Conversion Required
Head of the Liquid: 5 Meter --> 5 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C_v = sqrt(1-(h_f/H)) --> sqrt(1-(1.2/5))

Evaluating ... ...

C_v = 0.871779788708135
