Table of k values for minor losses

WebThe minor loss coefficient - ξ - values ranges from 0 and upwards. For ξ = 0 the minor loss is zero and for ξ = 1 the minor loss is equal to the dynamic pressure or head. The minor loss coefficient can also be greater than 1 for some components. The minor loss coefficient can be expressed by rearranging (1) to WebJun 1, 2006 · k = Darcy's f for the material * Leq / D. If not, the losses can't be 0.0, and have to be less than the amt. for 45d bends. Try identifying the operating point, using the system curves with both 0.0 and the 0.1, or whatever you got assuming all 45's.
