alfers101 3 years ago convert 53.342 ft-lb/lbm o R to Btu/lbm o R

1. zordoloom

Are you trying to convert 53.342 ft-lb/lbm to BTU/lb ?

2. alfers101

yes it's with R (rankine)

3. zordoloom

So pound-force feet per pound Rankine to IT british thermal units per pound Rankine (degree)?

4. alfers101

yes

5. zordoloom

I don't think they are compatible with one another.

6. alfers101

it is on the problem hmm.. i'll try to do that later, but how about pound-force feet per pound Rankine to KJ per Kg K

7. zordoloom

kelvin?

8. alfers101

yes

9. zordoloom

Can you post the question?

23. zordoloom

You still there?

24. alfers101

yes

25. zordoloom

What would that be?

26. alfers101

i think i should convert it first to: kJ/kg.K then convert it to Btu/lb.oR

27. zordoloom

The conversion is up to you. I've already solve it this way.

28. zordoloom

*solved.

29. zordoloom

Take a look at this:

30. zordoloom

Let me know if you follow.
