Equivalent Length Method. The equivalent length method (The L e /D method) allows the user to describe the pressure loss through an elbow or a fitting as a length of straight pipe.. This method is based on the observation that the major losses are also proportional to the velocity head (v 2 /2g).. The L e /D method simply increases the multiplying factor in the Darcy-Weisbach equation (i.e. pipe fitting k factors in portugal

If the pipe is less than 50 metres long, add an allowance for fittings of 10% to 20%. If the pipe is over 100 metres long and is a fairly straight run with few fittings, an allowance for fittings of 5% to 10% would be made. A similar pipe length, but with more fittings, would increase the allowance towards 20%.
