Diffusivity not available

Please note that the units for conditions used here could be different from the ones on the data you have. Another important factor to make a note of it unit conversions. If for example your pressure units are in Bar g, that roughly translates to adding 1.013 into the value you have to convert it into atmospheric units for pressure. Since g means gauge pressure, the numerical value for conversion to atm units could differ based on sea level of the location where original experiment is performed and/or data is collected. But for general purposes and feasibility of answers, it is safe to assume that adding 1.013 to Bar g value will yield Pressure in atm equivalent to the original value. If you see an error like the following, please know that the pressure is too low and the system is vaporizing to gaseous phase.
