2. Water Equivalent Diameter (Dw) Previous work has eed the x-ray attenuation of a patient in terms of a water cylinder having the same x-ray absorption [5-9]. The area and diameter of such a cylinder of water are referred to as the water equivalent area (A w) and water equivalent diameter (D w), respectively.

Nav Item; Hydraulic Diameter - Engineering ToolBoxThe equivalent diameter is the diameter of a circular duct or pipe that gives the same pressure loss as a rectangular duct or pipe. Sponsored Links Related Topics Hydraulic Diameter NeutriumEquivalent Diameter An alternative to the hydraulic diameter, called the equivalent diameter was developed in 1948. The equivalent diameter aims to use empirically determined relationships between non-circular geometries and the equivalent diameter to

The equivalent diameter aims to use empirically determined relationships between non-circular geometries and the equivalent diameter to achieve the same outcome as the hydraulic diameter. Current research (Koch, 2008) concludes that the equivalent diameter is a poor approximation and should not be used for pressure loss calculations. Hydraulic Radius PIPE EQUIVALENT LENGTH CALCULATOR - EngTankINSTRUCTION At left side is a pipe equivalent calculator developed by OilGas Engineers. Below is the steps to calculate a piping system equivalent length:Select a nominal pipe size, NPS. Fill in straight pipe length in feet. Fill the number of valves, fittings in the piping system. Scroll to Pressure Loss from Fittings - Equivalent Length Method Typically as the fittings size increase the flow coefficient (L/D ratio) decreases, thus at pipe sizes larger than those at which the fittings equivalent length was determined the pressure drop will be over-estimated. At smaller pipe sizes than those at which the equivalent length was estimated the pressure drop will be under-estimated.

The length of the rectangular duct size would range from 0.7mm to 0.9mm galvanised mild steel depending on size. Provided here is the rectangular duct sizes chart for your personal reference and this chart / table shows the duct size (cfm) and their equivalent diameter in inches. Solved:What Is The Equivalent Particle Diameter (mm) Of A Equivalent diameter of sphere is defined as diameter of a sphere of equal volume So first find out view the full answer Tire diameter chart TireBuyerTire size equivalent chart for 33", 35", 37" or 40" tires: It might say it is a 35X12.50-20, but the actual diameter noted in the specs is 34.6". The chart below should give you a good idea for the various tire size equivalents for popular truck sizes. TireBuyer has one of the largest selections of All Terrain and Mud Terrain tires in stock

Just type in a metric or standard size tyre and click calculate. Inch measurement tyres are fairly easy to understand however metric tyres use a more difficult system to read. The first number on a metric tyre is the width. Divide this by 25.4 to get inch equivalent. The third number generally preceded by an "R" is concrete_pipe_sizes SD&WPipe Size (in.) Round Equiv.

Plugging in the volume of 890.5 km 3 gives us a volume equivalent diameter of 11.9 km. The second approach is to determine the surface equivalent diameter which is the diameter of a sphere having the same surface area as the asteroid.

The equivalent diameter is defined as the diameter of a circle with an equal aggregate sectional area, which is calculated by d = 2 Area / . This is a classic method of an aggregate classification and used in many digital image processing programs.
