Pressure Drop In Elbow And Bend

Pressure Drop In Elbow And Bend. Sookprasong (1980), (1983), and paliwada (1992) developed correlations based on two phase multiplier method. Although pressure drop is a function of the square of the flow rate, the friction factor can change dramatically with velocity.

Dp = C * Q^2 Where Dp = Pressure Drop C = A Constant For Any Given Piping System Q = Flow Rate But The C In The Equation Is A Function Of Friction Factor, F, Which Varies With Flow.

The diameter of the pipeline has been taken as 50 mm nb. In fact, there may be a pressure drop or pressure gain due to the change of. Space availability, cost and pressure drop.

The Pressure Drop Across Elbows And Junctions [18, 4].

Diameter, flow rate, radius of bend, surface finish and reynolds number. As fluid flows through a pipe, a pressure drop will occur because of resistance to flow. That the horizontal to vertical upflow bend created the greater pressure drop.

Both These Factors Depend On The Bend Angle, The Curvature Ratio And The Reynolds Number.
