How do you determine pressure drop through fittings? - …

The pressure drop was expressed in units of Bell and Gosset Elbow equivalents. A rather strange unit, but certainly it could be understood by both an architect and a pipefitter.. And the best part is that the units were equally applicable to water, steam, and heating fuel oil without any complex mathematics.
