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 Co-efficient of contraction?

Co-efficient of contraction calculator uses coefficient of contraction=area of jet m/area of orifice to calculate the coefficient of contraction, The Co-efficient of contraction formula is defined as the ratio between the area of the jet at the vena-contracta and the area of the orifice. coefficient of contraction and is denoted by C c symbol.

FAQ

What is Co-efficient of contraction?
The Co-efficient of contraction formula is defined as the ratio between the area of the jet at the vena-contracta and the area of the orifice and is represented as C c=A c/a or coefficient of contraction=area of jet m/area of orifice. area of jet m is the total area of the liquid jet that is flowing and The area of orifice is often a pipe or tube of varying cross-sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas).
How to calculate Co-efficient of contraction?
The Co-efficient of contraction formula is defined as the ratio between the area of the jet at the vena-contracta and the area of the orifice is calculated using coefficient of contraction=area of jet m/area of orifice. To calculate Co-efficient of contraction, you need area of jet m (A c) and area of orifice (a). With our tool, you need to enter the respective value for area of jet m and area of orifice 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 contraction?
In this formula, coefficient of contraction uses area of jet m and area of orifice. We can use 2 other way(s) to calculate the same, which is/are as follows -
  • coefficient of contraction=velocity at section 2 2/(velocity at section 2 2+sqrt(loss of head sudden contraction*2*[g]))
  • coefficient of contraction=Coefficient of Discharge /coefficient of velocity
