WebUnits for Gas Leak Rate Calculation: atm=atmosphere, cm=centimeter, ft=foot, g=gram, hr=hour, k=kilo (1000), kPa=kiloPascal, kg=kilogram, lb=pound, m=meter, min=minute, … WebJul 15, 2008 · Note this is a pinhole leak not a pinhead leak which would be about twice the diameter. Using dcasto's excellent formula and noting that the diameter of the pipeline and the rate through the pipeline have nothing to do with the question, unless the pipeline diameter is approaching that of a pin, the leak rate through the pinhole is about 120 SCFH. cymbalta while breastfeeding
