The ,hydraulic diameter,, D H, is a commonly used term when handling flow in noncircular tubes and channels. Using this term one can calculate many things in the same way as for a round tube. Definition: where A is the cross sectional area and P is the wetted perimeter of the cross-section.. For a round tube, this checks as: The Manning formula contains a quantity called the ,hydraulic, radius.

Equivalent diameter is not the same as hydraulic diameter.

Hydraulic Diameter of a Circular Tube or Duct Based on equation (1) the hydraulic diameter of a circular duct can be expressed as: d h = 4 π r2 / 2 π r = 2 r (2) where r = pipe or duct radius (m, ft) As we could expect the hydraulic diameter of a standard circular tube or duct is two times the radius.

Diameter - Wikipedia

In geometry, a ,diameter, of a circle is any straight line segment that passes through the centre of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the ,diameter, of a sphere.. In more modern usage, the length of a ,diameter, is also called the ,diameter,.

One thing you can see is that the advertised "20-ton splitting force" is generous. A 4-inch piston has an area of 12.56 ,square, inches. If the pump generates a maximum pressure of 3,000 pounds per ,square, inch (psi), the total pressure available is 37,680 pounds, or about 2,320 pounds shy of 20 tons.
