Hi all I am struggling with this textbook example :( I have applied the formula but the numbers I am getting are really wrong!(adsbygoogle = window.adsbygoogle || []).push({});

A pump compressing hydrogen from a low pressure to a high pressure tank where the tanks pressure is constant and H2 is an ideal gas.

Hydrogen: (H2: MW = 2, Cv = 10 kJ/kgK)

Low pressure tank: (P = 4 bar, T = 30oC)

High pressure tank: (P = 100 bar).

1) Apply the first law of thermodynamics eliminating terms not needed

2) Find the compressor outlet temp when the compression goes along an adiabatic and polytrophic process
