The image above represents the total heat loss in the furnace. To calculate total heat loss in the furnace, four essential parameters are needed and these parameters are Absolute Temperature (Kelvin) (T), Factor of Total Radiation (a), Area of Opening (A) and Time (Hours) (H).

**The formula for calculating total heat loss in furnace:**

Q = 4.88(^{T}/_{100})^{4}Â x a x AH

Where:

Q = Total Heat Loss in Furnace

T = Absolute Temperature (Kelvin)

a = Factor of Total Radiation

A = Area of Opening

H = Time (Hours)

Let’s solve an example;

Find the total heat loss in furnace when the absolute temperature is 22, the factor of total radiation is 14, the area of opening is 10 and the time is 18.

This implies that;

T = Absolute Temperature (Kelvin) = 22

a = Factor of Total Radiation = 14

A = Area of Opening = 10

H = Time (Hours) = 18

Q = 4.88(^{T}/_{100})^{4}Â x a x AH

Q = 4.88(^{22}/_{100})^{4} x 14 x (10)(18)

Then, Q = 4.88(0.22)^{4} x 14 x 180

Q = 4.88(0.00234256) x 2520

Q = 28.807

Therefore, theÂ **total heat loss in furnaceÂ **isÂ **28.807 J/Kg K.**
