Enter value and click on calculate. Result will be displayed.
`K=0.8×sin(θ/2)×(1-β^2)`    ( θ ≤ 45° )
`K=1/2×(1-β^2)×(sin(θ/2))^[1/2]`    ( 45°< θ ≤180° )
θ = Angle of Approach
β = dminor / dmajor

Enter Your Values:

Angle of Approach:

(Enter Angle Less than 180°)

Pipe Contraction Calculator Changes in fluid velocity caused by changes in the fitting diameter are obtained by fitting. The pressure drop is also velocity dependent, changing in the direction of the fit. Example of use Input data: Gradient angle: 90; β: 10 Click "Calculate", K value: -45.6610
