Pipe Flow Calculations Forum

OK. That makes sense So the reported v1 & v2 are ARE velocities, and as you said you can determine these by multiplying the mass flow rate by the specific weight (I would divide by density, but that is the same thing). In either case, as you said the specific weight can be calculated using the i...

OK r.e. the normal conditions. In the equation/ theory description, you specify v1 as specific volume (and later specific weight), but the units displayed in the table on the bottom of the calculator are in distance / time (i.e. ft/s), which indicates velocity and not volume. So the question is: &qu...

Hello- After using the "Air pressure drop calculator" tool a few times, I am unable to account for a discrepancy - wondering if you will help me out? I'm passing air at -20°C through an 18" diameter pipe that is 100 ft long with an entrance pressure (p1) of 15.784 psia and a dP along ...
