Calculating Watt-Density
Watt-density is the power loading of the heater, expressed in watts-per-square-inch of active heater surface.
The formula for active heater surface is: (Heater Length – Cold End Length) x Diameter x Pi. For a 1/8” diameter by 1” long heater it is: (1.00 - 0.25) x .38, or .285 square inches.
The formula for watt-density is: Wattage / Active Heater Surface For 1/8” diameter by 1” heater at 80 watts, this is: 80 watts / .285 in sq or 270 watts/sq inch.
