Power required to generate gaseous Oxygen.

Hello, this is my first post, and I hope its in the correct forum!

As the title says, I'm interested in the power needed to generate gaseous Oxygen from LOX(liquid oxygen).
Specifically, the physics involved for an old UK missile/rocket, called Blue Streak.
Some info here for that rocket.:
Blue Streak.

I've done some work with Mathcad, and this is what I have so far:

I have a value of 376kW for this, but whats worrying me is the mass figure for Gas_Mass_Lox, the gaseous Lox from the heat-exchanger. Its completely different from HE_Lox_Flow, thats the mass going into the heat-exchanger.
I'm not sure any of the work I've done is accurate, just following physics text books and using the formulas. I suspect the error may be due to the change of state from liquid to gas in the heat exchanger, and my working dosen't take this into account?

All help appreciated.
