DETERMINING WATTAGE REQUIRED – basic formula
The energy to heat any substance = weight in lbs. X specific heat X temperature rise in °F = BTU
1 Kilowatt hour = 3412 BTU mathematically expressed:
Specific Heat is the amount of heat necessary to raise the temperature of a substance by 1 °F. Expressed as BTU/lb.°F.
The total wattage required to heat any substance consists of:
- ABSORPTION (watts consumed by heated substance in a given time)
- HEAT LOSSES (radiation losses and losses due to absorption by surrounding enclosure, shelves, etc.)
- HEAT OF FUSION (if the substance is to be melted)
HEAT OF VAPORIZATION (if the substance is to be vaporized)
The best of fusion is the amount of heat required to melt one pound of the material. The heat of vaporization is the heat required to vaporize one pound of the material. Each is normally listed in BTY/lb.
|Substance||Average Specific Heat BTU/lb./°F||Heat of Fusion BTU/lb.||Melting Point °F||Weight lbs./ft.3|
|Brickwork and Masonry||.220||….||……..||140|
|Solder (50% lead – 50% tin)||.04||17||415||580|
|Steel, stainless 304||.12||….||2550||495|
|Type metal85% lead15% antimony||.040||….||500||670|
|Substance||Average Specific Heat BTU/lb./°F||Heat of Vaporization BTU/lb.||Boiling Point °F||Weight lbs./ft.3||Weight Lb. Per Gallon|
GASES AND VAPORS
|Substance||Average Specific Heat BTU/lb./°F||Weight lbs./ft.3|
NOTE: These values are approximate, and only for 70 °F and atmospheric pressure. Specific heats and specific weights vary with temperature and pressure, so if your problem involves a material at temperature and/or pressure other than standard, these values may not apply. RAMA engineers maintain extensive files of data on these and many other less common materials and will be pleased to help you whenever possible.
