Hi! We have a data sheet from a shower which specifies a flow of 7,8 liters/minute at a pressure of 5.5 kgf/cm2 (which is equivalent to 5,39 Bar or 78 PSI). The problem that we have is that we are not sure if presenting this information with 78 psi instead of 80 will mean a problem for the reviewer or if neccessarily we will have to make a convertion (adjust the flow to 80 PSI) which in our case is very difficult as we don't know hoy to do it (for flow convertions related to pressure adjustments, calculations are not as simple as a cross multiplication or a proportion). Has any one had a similar experience?. Thanks so much for any help provided. Regards,
