Flow conversion....
(OP)
Hello,
I am having to convert several different flow rates for construction.
I have feet per sec and I am having to convert to standard cubic feet per sec.
Can someone post an easy conversion please.
Thanks

RE: Flow conversion....
Feet per second (ft/s) is a linear velocity. Cubic feet per sec (ft3/s) is a volumemetric flow. They are related as per:
Volumetric flow = (linear velocity)(flow area)
For example, let's take a linear velocity of 8 ft/s in a pipe with an inside diameter of 4 inches:
(1) flow area = (Pi)(diameter)2/4 = (3.14)(4)2/4 = 12.57 in2= 0.087 ft2
(2) Volumetric flow = (8)(0.087) = 0.7 ft3/s

Download a free copy of the units conversion program "CONVERT 4.1" from the web page www.joshmadison.com/software/convert/
It is an easy to use unit conversion program that will convert the most popular units of distance, temperature, volume, time, speed, mass, etc

I was just looking over your book "Fundamentals of Stack Gas Dispersion". We are currently building a Flare Gas Recovery unit to eliminate enviromental polution (H2S, etc..)
Thanks again y'all & Perth I downloaded the Convert tool :)

where the subscript a refers to actual conditions and the subscript s refers to standard conditions
Also, you may need to correct for compressibility depending on your operating pressure and your working fluid.
