Diffuse solar radiation given total solar energy and direct radiation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Diffuse solar radiation = Total solar energy-Direct solar radiation*cos(Angle of Incidence)
G_d = G_solar-G_D*cos(i)
This formula uses 1 Functions, 4 Variables

Functions Used

cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)

Variables Used

Diffuse solar radiation - (Measured in Watt per Square Meter) - Diffuse solar radiation is the scattered solar radiation reaching the earth’s surface uniformly from all directions.
Total solar energy - (Measured in Watt per Square Meter) - Total solar energy is the solar energy incident on the unit area of a horizontal surface on the ground.
Direct solar radiation - (Measured in Watt per Square Meter) - Direct solar radiation is the part of solar radiation that reaches the earth’s surface without being scattered or absorbed by the atmosphere.
Angle of Incidence - (Measured in Radian) - Angle of Incidence is the angle which an incident line or ray makes with a perpendicular to the surface at the point of incidence.

STEP 1: Convert Input(s) to Base Unit

Total solar energy: 950 Watt per Square Meter --> 950 Watt per Square Meter No Conversion Required
Direct solar radiation: 800 Watt per Square Meter --> 800 Watt per Square Meter No Conversion Required
Angle of Incidence: 40 Degree --> 0.698131700797601 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

G_d = G_solar-G_D*cos(i) --> 950-800*cos(0.698131700797601)

Evaluating ... ...

G_d = 337.16444550475

STEP 3: Convert Result to Output's Unit

337.16444550475 Watt per Square Meter --> No Conversion Required

FINAL ANSWER

337.16444550475 ≈ 337.1644 Watt per Square Meter <-- Diffuse solar radiation

(Calculation completed in 00.020 seconds)

Go Diffuse solar radiation = Total solar energy-Direct solar radiation*cos(Angle of Incidence)

Diffuse solar radiation given total solar energy and direct radiation Formula

Diffuse solar radiation = Total solar energy-Direct solar radiation*cos(Angle of Incidence)
G_d = G_solar-G_D*cos(i)

Why the sky is blue in colour?

The sky is blue in clour because the air molecules scatter blue light much more than they do red or other lights. At sunset, the light travels through a thicker layer of the atmosphere, which removes much of the blue from the natural light, allowing the red to dominate.
