Net Energy Leaving given Radiosity and Irradiation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Heat Transfer = Area*(Radiosity-Irradiation)
q = A*(J-G)
This formula uses 4 Variables

Variables Used

Heat Transfer - (Measured in Watt) - Heat Transfer is the amount of heat that is transferred per unit of time in some material, usually measured in watts (joules per second).
Area - (Measured in Square Meter) - The area is the amount of two-dimensional space taken up by an object.
Radiosity - (Measured in Watt per Square Meter) - Radiosity represents the rate at which radiation energy leaves a unit area of a surface in all directions.
Irradiation - (Measured in Watt per Square Meter) - Irradiation is the radiation flux incident on a surface from all directions.

STEP 1: Convert Input(s) to Base Unit

Area: 50.3 Square Meter --> 50.3 Square Meter No Conversion Required
Radiosity: 308 Watt per Square Meter --> 308 Watt per Square Meter No Conversion Required
Irradiation: 0.8 Watt per Square Meter --> 0.8 Watt per Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

q = A*(J-G) --> 50.3*(308-0.8)

Evaluating ... ...

q = 15452.16

STEP 3: Convert Result to Output's Unit

15452.16 Watt --> No Conversion Required

FINAL ANSWER

15452.16 Watt <-- Heat Transfer
