Hydraulic Diameter - Engineering ToolBox

Hydraulic Diameter vs. Equivalent Diameter; Note that the velocity in the Reynolds equation is based on actual cross section area of duct or pipe. The hydraulic diameter is used to calculate pressure loss in ducts or pipes. Note! - the hydraulic diameter is not the same as the geometrical equivalent diameter of non-circular ducts or pipes.

CPT Rigs for soil investigation, soil test CPT cone test

CPT Rigs (Cone Penetrometer Test Rigs) are used for pushing CPT cones into the ground to obtain readings such as tip pressure, friction sleeve readings, pore pressure and seismic readings. This data is then used to interpret and classify soil conditions for numerous purposes, including determining the bearing capacity of the soil for construction.
