    Oxygen Power
AI Thread Summary
The discussion focuses on the power required to vaporize liquid oxygen (LOX) for the Blue Streak missile. The user has calculated a power requirement of 376 kW but is concerned about discrepancies between the mass flow rates of gaseous LOX and the mass entering the heat exchanger. They seek validation of their calculations and any insights into the physics involved. The user is also looking for guidance on whether they are posting in the correct forum or if there are better alternatives. Input from knowledgeable members is requested to clarify these technical issues.

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.

Thread 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'
Here are two fragments from Banach's monograph in Mechanics I have never seen the term <<velocity of transport>> in English texts. Actually I have never seen this term being named somehow in English. This term has a name in Russian books. I looked through the original Banach's text in Polish and there is a Polish name for this term. It is a little bit surprising that the Polish name differs from the Russian one and also differs from this English translation. My question is: Is there...
I know that mass does not affect the acceleration in a simple pendulum undergoing SHM, but how does the mass on the spring that makes up the elastic pendulum affect its acceleration? Certainly, there must be a change due to the displacement from equilibrium caused by each differing mass? I am talking about finding the acceleration at a specific time on each trial with different masses and comparing them. How would they compare and why?
