SPECIFIC HEAT OF HYDROGEN 1

[charlesxavier]

I need found specific heat of hydrogen at 220 psig for desing a heat exchanger.

 

[moltonian]

What is the temperature range you are interested in? (Is the hydrogen gas or liquid?)

To moltonian: I´m working 10°F - 100°F as temperature range, in a heat exchanger with ammonia vapor, in a equipment of absorption refrigeration to academic purposes

Thanks Gunnar: ¿Where found you this information?

Charles,

I calculated these values using a program called Flashcalc by Momentum Engineering (
