on . Posted in Fluid Dynamics

Hydraulic diameter, abbreviated as $$d_h$$, of a square tube is when the flow is within the tube.

## Hydraulic Diameter of a Square Tube formula

$$\large{ d_h = w }$$
Symbol English Metric
$$\large{ d_h }$$ = hydraulic diameter $$\large{in}$$ $$\large{mm}$$
$$\large{ w }$$ = width of tube $$\large{in}$$ $$\large{mm}$$
