Pressure of Nitrous oxide cylinder at 100% and 40% volume respectively measured by pressure gauge is:
750 Psi and 500 Psi
750 Psi and 750 Psi
750 Psi and 375 Psi
750 Psi and 275 Psi
In cases of gases which are in liquid form in cylinder ( N2O) , pressure gauze shows always full till it becomes Zero Thus in case of N2O , whether cylinder has 100% or 40% volume , pressure gauze will always show 750 Psi.
