Open-channel & pressure-pipe flow
Everyday hydraulics in US customary units — Manning's equation for open channels, the Bernoulli energy equation between two points, pressure-pipe head loss (Darcy-Weisbach or Hazen-Williams with minor losses), and specific energy with critical & normal depth and the hydraulic jump. Every equation, substitution and variable definition is shown in full.
Open-Channel Flow
Manning's equation — rectangular, trapezoidal, triangular & circular channels; velocity, discharge, Froude.
Open →Bernoulli Energy
Energy equation between two points — solve pressure, velocity, elevation or head loss.
Open →Pipe Head Loss
Pressure-pipe head loss — Darcy-Weisbach (Swamee-Jain) or Hazen-Williams plus minor losses.
Open →Specific Energy
Specific energy, critical & normal depth, Froude number and the hydraulic-jump sequent depth.
