Calculation of superheated steam heat
Thread Content
I recall there being an estimate for the heat associated with superheated steam; it seems that 1 joule of heat is absorbed per cubic meter of steam for every degree increase in its superheating temperature. I’m not sure if this is correct, so please correct me if I’m wrong. Thank you.
It’s likely that the original poster made a mistake; it should be 1 kcal rather than 1 J. The specific heat of steam between 100 and 165°C is approximately 2.1 kJ/kg·K, and its density is about 2 kg/m3. Based on these values, it takes roughly 1 kilocalorie for the temperature of steam to increase by 1 degree within this range.
It refers to the amount of heat required per kilogram of water under standard conditions, for every 1-degree increase in temperature, which is 1 kcal = 4.1868 kJ
