Absorptivity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Absorptivity = Absorbed Radiation/Incident Radiation
α = G_abs/G_i
This formula uses 3 Variables

Variables Used

Absorptivity - The Absorptivity is a measure of how much radiation is absorbed by a surface, influencing heat transfer and energy efficiency in various applications.
Absorbed Radiation - (Measured in Watt per Square Meter) - The Absorbed Radiation is the portion of incident radiation energy that is absorbed by a material, influencing its temperature and thermal behavior.
Incident Radiation - (Measured in Watt per Square Meter) - The Incident Radiation is the energy from electromagnetic waves striking a surface, influencing heat transfer and material interactions in various engineering applications.

STEP 1: Convert Input(s) to Base Unit

Absorbed Radiation: 390 Watt per Square Meter --> 390 Watt per Square Meter No Conversion Required
Incident Radiation: 600 Watt per Square Meter --> 600 Watt per Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

α = G_abs/G_i --> 390/600

Evaluating ... ...

α = 0.65

STEP 3: Convert Result to Output's Unit

0.65 --> No Conversion Required

FINAL ANSWER

0.65 <-- Absorptivity

Absorbed Radiation using Incident, Reflected and Transmitted Radiation

Go Absorbed Radiation = Incident Radiation-Reflected Radiation-Transmitted Radiation

Absorbed Radiation using Absorptivity and Incident Radiation

Go Absorbed Radiation = Absorptivity*Incident Radiation

Absorptivity

Go Absorptivity = Absorbed Radiation/Incident Radiation

Absorptivity using Reflectivity and Transmissivity

Go Absorptivity = 1-Reflectivity-Transmissivity

Absorptivity Formula

Absorptivity = Absorbed Radiation/Incident Radiation
α = G_abs/G_i

What is Absorptivity?

When radiation strikes a surface, part of it is absorbed, part of it is reflected, and the remaining part, if any, is transmitted. The fraction of irradiation absorbed by the surface is called the absorptivity

How to Calculate Absorptivity?

Absorptivity calculator uses Absorptivity = Absorbed Radiation/Incident Radiation to calculate the Absorptivity, Absorptivity formula is defined as a measure of the amount of radiation absorbed by a substance, describing the ability of a material to absorb radiation energy, which is essential in understanding the interaction between radiation and matter in various fields such as physics, chemistry, and biology. Absorptivity is denoted by α symbol.
