SPECIFIC HEAT OF HYDROGEN

SPECIFIC HEAT OF HYDROGEN

SPECIFIC HEAT OF HYDROGEN

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

RE: SPECIFIC HEAT OF HYDROGEN

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

RE: SPECIFIC HEAT OF HYDROGEN

Dear Charles,

Hydrogen Vapor Heat Capacity


Peng-Robinson EOS
Pressure = 214.7 psia

RE: SPECIFIC HEAT OF HYDROGEN

(OP)
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

RE: SPECIFIC HEAT OF HYDROGEN

(OP)
Thanks Gunnar: ¿Where found you this information?

RE: SPECIFIC HEAT OF HYDROGEN

Charles,

I calculated these values using a program called Flashcalc by Momentum Engineering (www.momentumware.com)

Regards,

Gunnar
