Irradiation Solution

Follow our step by step solution on how to calculate Irradiation?

FIRST Step Consider the formula

H = \frac{L p}{A}

Next Step Substitute values of Variables

∴

H = \frac{22W}{28.5m²}

Next Step Prepare to Evaluate

∴

H = \frac{22}{28.5}

Next Step Evaluate

∴

H = 0.771929824561403W/m²

LAST Step Rounding Answer

∴

H = 0.7719W/m²

How to Evaluate Irradiation?

Irradiation evaluator uses Irradiation = Power/Surface Area to evaluate the Irradiation, The Irradiation formula is defined as is the process by which an object is exposed to radiation. The exposure can originate from various sources, including natural sources. Irradiation is denoted by H symbol.

How to evaluate Irradiation using this online evaluator? To use this online evaluator for Irradiation, enter Power (L_p) & Surface Area (A) and hit the calculate button.

FAQs on Irradiation

What is the formula to find Irradiation?

The formula of Irradiation is expressed as Irradiation = Power/Surface Area. Here is an example- 0.291228 = 22/28.5.

How to calculate Irradiation?

With Power (L_p) & Surface Area (A) we can find Irradiation using the formula - Irradiation = Power/Surface Area.

Can the Irradiation be negative?

No, the Irradiation, measured in Heat Flux Density cannot be negative.

Which unit is used to measure Irradiation?

Irradiation is usually measured using the Watt per Square Meter[W/m²] for Heat Flux Density. Kilowatt per Square Meter[W/m²], Watt per Square Centimeter[W/m²], Watt per Square Inch[W/m²] are the few other units in which Irradiation can be measured.
