IS NITROGEN SOLUBLE IN WATER? IF IT IS, HOW DO YOU CALCULATE THE LOSS OF WATER IN DETERMINING THE NPSH? IS THERE A WAY TO PREVENT THE LOSS OF HEAD?

RE: IS NITROGEN SOLUBLE IN WATER?
Quantifying the impact on dissolved gases on NPSH is not straightforward, I saw one article on it years ago which I either didn't copy for my files or which I've mis-filed and can't now locate
RE: IS NITROGEN SOLUBLE IN WATER?
~18 ppm @ 10ºC
~14 ppm @ 25ºC
~10 ppm @ 60ºC
I don't really see how it affects NPSH, though. I don't think the amount of dissolved nitrogen in water will change the NPSHR of a pump at all. I also don't see how it will affect the head, unless you add nitrogen blanket a storage tank such that the addition of nitrogen increases the pressure in the tank. In that case, the head (NPSHA) will increase.
If I am misinformed, please correct me.
