Pressure drop in pipe fittings and valves | equivalent ...

As was shown above in section 3.4.1, when working with smooth pipe the resistance coefficient (K) for the fitting remains the same but the equivalent length (L e /D) changes. It is therefore wrong to take the Crane (L e /D) values and use the lower friction factor in smooth pipe to generate a lower resistance coefficient (K) from Equation (9).
