I need to know the specific heat value for water at 711 psig (49 Kg/cm2) and 185 deg C (385 deg F) in Kcal/kg degC or BTU/lb deg F
 
Hi,

Does heat capactity vary with pressure? I wouldn't have thought so.

Cheers,
John. Cheers,

There is a very, very slight effect of pressure on the heat capacity of water (CRC Handbook of tables for Applied Engineering Science) but it's essentially zero. As a quick look at the Mollier diagram for water would have shown.
 
From CRC

mean from 0-180 deg C: 1.0127 cal/g/C Variation fro 0-100 is very slight (high at 0: 1.00738 cal/g/C and low at 34 deg C: 0.99798 cal/g/C)

Best regards

Morten
