Significance of coefficient of discharge
WebSimple hydraulic structures, such as weirs, allow measuring flow discharge by using the upstream flow depth and a stage–discharge relationship. In this relationship, a discharge coefficient is introduced to correct all the effects neglected in the derivation (viscosity, surface tension, velocity head in the approach channel, flow turbulence, non … WebWhat is the general value of coefficient of discharge? The discharge coefficient can vary significantly from the basic broad-crested value of 1.705 and depends largely on the …
