Coefficient of velocity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Coefficient of Velocity = Actual Velocity/Theoretical Velocity
C_v = v_a/V_th
This formula uses 3 Variables

Variables Used

Coefficient of Velocity - The Coefficient of Velocity is the ratio of actual velocity to theoretical velocity.
Actual Velocity - (Measured in Meter per Second) - Actual velocity is the velocity at which a microscopic particle of dust would be traveling if it were in the air stream.
Theoretical Velocity - (Measured in Meter per Second) - Theoretical velocity is defined as the velocity that is calculated theoretically.

STEP 1: Convert Input(s) to Base Unit

Actual Velocity: 8 Meter per Second --> 8 Meter per Second No Conversion Required
Theoretical Velocity: 9 Meter per Second --> 9 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C_v = v_a/V_th --> 8/9

Evaluating ... ...

C_v = 0.888888888888889

STEP 3: Convert Result to Output's Unit

0.888888888888889 --> No Conversion Required

FINAL ANSWER

0.888888888888889 ≈ 0.888889 <-- Coefficient of Velocity

What is an orifice?

The orifice is defined as the small opening on the side or bottom of a tank through which any kind of fluid is flowing. The opening can be circular, triangular, or rectangular in cross-section and they are named on the basis of shape accordingly.

What is vena contracta?

Vena contracta is the point in a fluid stream where the diameter of the stream is the least, and fluid velocity is at its maximum, such as in the case of a stream issuing out of a nozzle. It is a place where the cross-section area is minimum.

How to Calculate Coefficient of velocity?

Coefficient of velocity calculator uses Coefficient of Velocity = Actual Velocity/Theoretical Velocity to calculate the Coefficient of Velocity, The Coefficient of velocity formula is defined as the ratio between the actual velocity of the jet at the vena-contracta to the theoretical velocity at the jet. Coefficient of Velocity is denoted by C_v symbol.

How to calculate Coefficient of velocity using this online calculator? To use this online calculator for Coefficient of velocity, enter Actual Velocity (v_a) & Theoretical Velocity (V_th) and hit the calculate button. Here is how the Coefficient of velocity calculation can be explained with given input values -> 0.285714 = 8/9.

FAQ

What is Coefficient of velocity?

The Coefficient of velocity formula is defined as the ratio between the actual velocity of the jet at the vena-contracta to the theoretical velocity at the jet and is represented as C_v = v_a/V_th or Coefficient of Velocity = Actual Velocity/Theoretical Velocity. Actual velocity is the velocity at which a microscopic particle of dust would be traveling if it were in the air stream & Theoretical velocity is defined as the velocity that is calculated theoretically.

How to calculate Coefficient of velocity?

The Coefficient of velocity formula is defined as the ratio between the actual velocity of the jet at the vena-contracta to the theoretical velocity at the jet is calculated using Coefficient of Velocity = Actual Velocity/Theoretical Velocity. To calculate Coefficient of velocity, you need Actual Velocity (v_a) & Theoretical Velocity (V_th). With our tool, you need to enter the respective value for Actual Velocity & Theoretical Velocity and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Coefficient of Velocity?

In this formula, Coefficient of Velocity uses Actual Velocity & Theoretical Velocity. We can use 2 other way(s) to calculate the same, which is/are as follows -

Coefficient of Velocity = Horizontal Distance/(sqrt(4*Vertical Distance*Head of the Liquid))
Coefficient of Velocity = sqrt(1-(Head Loss/Head of the Liquid))
