Average Specific Heat of ... {replace the text - after the title, before the table - for all specific heats on charge material, fixture, atmosphere pages} Amount of heat per unit mass required to raise the temperature by one degree. For most materials, specific heat changes with temperature. At low temperatures, this change is negligible and it can be assumed that specific heat is constant across the temperature differential. At higher temperatures, the material's specific heat increase is more substantial. This makes heat loss or heat demand calculations difficult. As MEASUR does not take this change into account, it is recommended that an average value of specific heat for a certain temperature range is used. MEASUR provides an default value for several materials.

Average Specific Heat of ... {replace the text - after the title, before the table - for all specific heats on cooling page} Amount of heat per unit mass required to raise the temperature by one degree. For most materials, specific heat changes with temperature. At low temperatures, this change is negligible and it can be assumed that specific heat is constant across the temperature differential. At higher temperatures, the material's specific heat increase is more substantial. This makes heat loss or heat demand calculations difficult. As MEASUR does not take this change into account, it is recommended that an average value of specific heat for a certain temperature range is used. Default value is for {air/water}; if at high temperatures, consider using another value.

Water content... Water content of the charge material as percentage of total charge weight - wet basis. This value can be obtained from moisture tests or specifications for the material charged. It can also be the moisture (water or snow) entering the furnace on the charge material. For example – steel scrap going in EAFs sometime includes snow or moisture. This could also be set to zero and another charge material (water) added.
