Information

Minor-loss resistance for a single-joint mitered (sharp) pipe bend – a pipe that changes direction at a sharp joint with no curvature radius. The pressure loss is

dp = K*m_flow^2/(2*rho*A^2)

with the resistance coefficient from the Rennels & Hudson (2012) correlation (K_miterBend), K = 0.42 sin(α/2) + 2.56 sin³(α/2), valid to about 150°. A mitered bend is markedly more lossy than a smooth bend (Elbow) of the same angle. Flow reversal is supported (the loss opposes the flow). Circular cross-section.
