Pressure loss pipe fittings during a laminary flow
Pressure loss pipe fittings during a laminary flow
(OP)
Hi,
I have got the following question. With turbulent flow fittings have got an almost constant loss factor. It can be found in the literature and internet. Now I am confronted with the question to calculate pressure loss over a fitting with laminary flow. I know that turbulent flow results in a quadratic function ( dP = K*1/2*rho*v^2 ). This goes for the piping itself and the fittings. With laminary flow though the relationship between pressure loss and flow velocity is linear. I assume that the fittings in this case will also behave as a linear resistance. Where can I find the bygoing constants?
