Dear go-fish

the forula for calcuating the gas density seems to be wrong.

vapor density = MW*(gauge pressure+1.01325)*100000/8314.4/(temperature+273)/compressibity

The pressue, given such as v2/2g is abosolute pressure instead of gauge pressure.

so I think you don't have to add up the 1.01325

Please give me comment if I am wrong
