The fluid systems learner
toolbox.
Track flow, head, pressure losses and ideal hydraulic power.
10 useful places to start.
Density, viscosity, coefficients and geometry are supplied inputs; transition and approximation limits are explicit.
Pipe mean flow velocity
Find mean liquid speed from circular bore diameter and volume flow.
Pipe Reynolds number
Calculate Reynolds number with explicit density and dynamic viscosity.
Darcy pipe friction loss
Estimate straight-pipe pressure loss using a flow-regime-aware Darcy factor.
Pipe fitting minor-loss table
Combine fitting loss coefficients on one velocity basis.
Liquid orifice discharge
Estimate discharge from head, circular opening size and a supplied coefficient.
Venturi liquid flow estimate
Calculate volume flow from upstream/throat diameters and differential pressure.
Gravity tank drain curve
Plot liquid head and outflow as a constant-area tank drains.
Manning open-channel flow
Estimate uniform flow in a rectangular or trapezoidal channel.
Hydraulic cylinder force & speed
Compare extension and retraction force, speed and stroke time.
Hydraulic fluid & shaft power
Convert pressure difference and volume flow into fluid power and input power.
A few things you
can tick off.
- Check pipe-flow regimes
- Plot a gravity drain curve
- Compare hydraulic force and speed
