Radiosity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Radiosity = Energy Leaving Surface/(Body Surface Area*Time in seconds)
J = E_Leaving/(SA_Body*t_sec)
This formula uses 4 Variables

Variables Used

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.
Energy Leaving Surface - (Measured in Joule) - Energy Leaving Surface is defined as the total amount of emitted and reflected radiation leaving a surface, in the fields of optics and heat transfer.
Body Surface Area - (Measured in Square Meter) - Body Surface Area is the total surface area of the human body.
Time in seconds - (Measured in Second) - Time in seconds is what a clock reads, it is a scalar quantity.

STEP 1: Convert Input(s) to Base Unit

Energy Leaving Surface: 19 Joule --> 19 Joule No Conversion Required
Body Surface Area: 8.5 Square Meter --> 8.5 Square Meter No Conversion Required
Time in seconds: 38 Second --> 38 Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

J = E_Leaving/(SA_Body*t_sec) --> 19/(8.5*38)

Evaluating ... ...

J = 0.0588235294117647

What is Heat Transfer?

Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes.

Define Thermal Conductivity & Factors affecting it?

Thermal conductivity is defined as the ability of a substance to conduct heat. Factors Affecting The Thermal Conductivity are: Moisture, Density of material, Pressure, Temperature & Structure of material.

How to Calculate Radiosity?
