Power required to make gaseous Oxygen

[Notebook]

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 vaporise LOX(liquid oxygen).

Specifically the physics involved for an old UK missile/rocket, called Blue Streak.
Some info here for that rocket.:

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

I have a value of 376Kw for this, but what's worrying me is the figure for Gas_Mass_Lox, the gaseous Lox from the heat-exchanger. Its completely different from HE_Lox_Flow. that's the mass going into the heat-exchanger.

I'm not sure any of the work I've done is accurate, just following some textbooks and using the formulas.

All help appreciated.

Apologies for bumping this thread, just with no replies at all, I'm worried I caught the forum at a busy time and it disapeared into the distance!

If this is the wrong part of the forum, please advise, or if anyone knows of another one I can post to.

All input appreciated.
