So you need to enter %TR, the test value, in order to get the right TR from P or the right P from TR. The calculations only work if the thickness units for P are the same as the units chosen for thickness. If your units for P give values such as 3.2e -14 just enter the 3.2 and assume the e -14. If there were just one or two units for P then the

On a compressed air distribution system, pressure losses greater than 3% are considered excessive, and a well-designed system having a steady rate of air flow is usually designed for not more than a 1% loss or 1 PSI for a 100 PSI system. The pipe size depends not only on the volume of air flow but how far it must be carried. To hold the distribution loss to 1 PSI, pipes of …

FEP Teflon is the preferred choice for soil vapor gas intrusion sampling. Teflon''s high-temperature threshold and resistance to chemicals and other VOCs mean that it does not affect the test sample. Unlike PTFE Teflon, FEP does not contain PFAS or PFOA, making it acceptable to be used on sites with PFAS contamination. FEP Teflon is approved by the DTSC for all soil …
