Hi

Understood the below links gives K-value for some of the fitting however, it doesn't show the assumed value for different default bends and tees . Please could you be able to post the k vale for the default connection fittings. i want to verify the pressure loss is correct and is inline with CIBSE guide C.

Many Thanks
