The equivalent diameter is the diameter of a circular duct or pipe that gives the same pressure loss as an equivalent rectangular duct or pipe. The table below can be used to compare equivalent diameters for rectangular and round circular ducts.
Calculate hydraulic diameter for pipes and ducts. Hydraulic diameter - dh - is the "characteristic length" used to calculate the dimensionless Reynolds Number to determine if a flow is turbulent or laminar. A flow is. laminar if Re < 2300. transient for 2300 < Re < 4000. turbulent if Re > 4000. Hydraulic Diameter vs. Equivalent Diameter.
Online calculator to quickly determine Pipe Sizing by Velocity for Water. Includes 53 different calculations. Equations displayed for easy reference.
Calculation of pipe diameter with the pipe diameter calculator is easy. You can use pipe diameter and flow rate calculator for quick pipe diameter calculation in a closed, round, rectangle (online calculator version only) and filled pipes with liquid or perfect gas.
This calculator allows you to estimate the minimum value of the inner diameter of the pipe at a given velocity of the medium and the capacity of the pipeline. The basic formula: d = √ [(4 × Q) / (V × π)] , where Q – flow rate, V – water velocity.
Free online Flow Rate calculator which helps you calculate the flow rate of any pipe given its diameter and liquid/gas velocity or its height and width (for a rectangular pipe) and velocity. Calculate flow rate from pressure. Fluid flow rate through pipe given pressure difference at two points.
