Fluid mechanics head loss

WebThe head loss Δh (or hf) expresses the pressure loss due to friction in terms of the equivalent height of a column of the working fluid, so the pressure drop is where: Δh = The head loss due to pipe friction over the given length of pipe (SI units: m); [b] g = The local acceleration due to gravity (m/s 2 ). WebThe head loss coefficient (K) is calculated as the ratio of the manometric head difference between the input and output of the fitting to the velocity head. Due to the change in the pipe cross-sectional area in enlargement and contraction fittings, the velocity difference cannot be …
