Here is the quick and simple heating equation and variables needed to heat an application.
Required BTU's or KW are calculated with this equation.
WxSHxΔT =BTU/hour
Weight (lb) of material being heated = W
Specific Heat of material = SH
Change in Temperature needed or Delta T = ΔT
To Convert BTUs to KW, divide the BTUs by 3413.
This equation only yields the heat input and does not take into consideration any heat losses or heat gains within a process. If an application is heating water but then a solid piece of metal enters into the water, the solid mud be heated too as well as the tank to achieve the goal system KW required.
Below are specific Heat values for common substances along with weights.
Specific Heats listed are all below 1 except Water which is 1.
Solid weights are per cubic foot and liquid weights are per gallon in pounds.
