Irradiation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Irradiation = Power/Surface Area
H = L_p/A
This formula uses 3 Variables

Variables Used

Irradiation - (Measured in Watt per Square Meter) - Irradiation is the radiation flux incident on a surface from all directions.
Power - (Measured in Watt) - Power is a quantity permitting comparison of illuminances in the image planes of various optical systems.
Surface Area - (Measured in Square Meter) - Surface Area refers to the total area of a surface that light rays strike. This area determines the amount of light energy absorbed, reflected, or transmitted by the surface.

STEP 1: Convert Input(s) to Base Unit

Power: 22 Watt --> 22 Watt No Conversion Required
Surface Area: 28.5 Square Meter --> 28.5 Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

H = L_p/A --> 22/28.5

Evaluating ... ...

H = 0.771929824561403

STEP 3: Convert Result to Output's Unit

0.771929824561403 Watt per Square Meter --> No Conversion Required

FINAL ANSWER

0.771929824561403 ≈ 0.77193 Watt per Square Meter <-- Irradiation

Reflected Luminous Flux

Go Reflected Luminous Flux = Incident Luminous Flux*Reflection Factor

Intensity on Solid Angle

Go Luminous Intensity = Magnetic Flux/Area Projected at Solid Angle

Flux at Solid Angle

Go Magnetic Flux = Luminous Intensity*Area Projected at Solid Angle

Area affected by Light Incident

Go Surface Area = Power/Irradiation

Irradiation Formula

Irradiation = Power/Surface Area
H = L_p/A
