Values of Pressure loss coefficient (Cr)

The Pressure loss coefficient Cr is the function of included angle θ of the sides of contraction/ reduction.

Following are the general values of Cr with respect to the θ:

1. θ (in degree) = 5 then Cr = 0.17
2. θ (in degree) = 7 then Cr = 0.22
3. θ (in degree) = 10 then Cr = 0.28
4. θ (in degree) = 20 then Cr = 0.45
5. θ (in degree) = 30 then Cr = 0.59
6. θ (in degree) = 40 then Cr = 0.73
