## Heat Flux Solution

STEP 0: Pre-Calculation Summary
Formula Used
Heat Flux = Thermal Conductivity of Fin*(Temperature of Conductor/Length of Conductor)
q' = kfin*(T/l)
This formula uses 4 Variables
Variables Used
Heat Flux - (Measured in Watt per Square Meter) - Heat Flux is the heat transfer rate per unit area normal to the direction of heat flow. It is denoted by the letter "q".
Thermal Conductivity of Fin - (Measured in Watt per Meter per K) - Thermal Conductivity of Fin is rate of heat passes through Fin, expressed as amount of heat flows per unit time through a unit area with a temperature gradient of one degree per unit distance.
Temperature of Conductor - (Measured in Kelvin) - Temperature of Conductor is the degree or intensity of heat present in a heat conductor.
Length of Conductor - (Measured in Meter) - Length of Conductor is the measure of length of wire.
STEP 1: Convert Input(s) to Base Unit
Thermal Conductivity of Fin: 10.18 Watt per Meter per K --> 10.18 Watt per Meter per K No Conversion Required
Temperature of Conductor: 85 Kelvin --> 85 Kelvin No Conversion Required
Length of Conductor: 11 Meter --> 11 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
q' = kfin*(T/l) --> 10.18*(85/11)
Evaluating ... ...
q' = 78.6636363636364
STEP 3: Convert Result to Output's Unit
78.6636363636364 Watt per Square Meter --> No Conversion Required
78.6636363636364 Watt per Square Meter <-- Heat Flux

## What is heat flux?

Heat flux or thermal flux, sometimes also referred to as heat flux density, heat-flow density or heat flow rate intensity is a flow of energy per unit of area per unit of time. In SI its units are watts per square metre (W/m2). It has both a direction and a magnitude, and so it is a vector quantity.

## How to Calculate Heat Flux?

Heat Flux calculator uses Heat Flux = Thermal Conductivity of Fin*(Temperature of Conductor/Length of Conductor) to calculate the Heat Flux, Heat flux or thermal flux, sometimes also referred to as heat flux density, heat-flow density or heat flow rate intensity is a flow of energy per unit of area per unit of time. Heat Flux is denoted by q' symbol.
