# How to Calculate and Solve for Quantity of Heat Loss | Fuel and Furnaces

Last Updated on July 31, 2021

The image above represents quantity of heat loss.

To compute for quantity of heat loss, four essential parameters are needed and these parameters are Initial Temperature (T1), Final Temperature (T2), a and E.

The formula for calculating quantity of heat loss:

Q = a(T1 – T2)5/4 + 4.88E[(T1 + 273/100)4 – (T2 + 273/100)4]

Where:

Q = Quantity of Heat Loss
T1 = Initial Temperature
T2 = Final Temperature

Let’s solve an example;
Find the quantity of heat loss when the initial temperature is 21, the final temperature is 17, a is 14 and E is 15.

This implies that;

T1 = Initial Temperature = 21
T2 = Final Temperature = 17
a = 14
E = 15

Q = a(T1 – T2)5/4 + 4.88E[(T1 + 273/100)4 – (T2 + 273/100)4]
Q = 14(21 – 17)5/4 + 4.88(15)[(21 + 273/100)4 – (17 + 273/100)4]
Q = 14(4)5/4 + 4.88(15)[74.71 – 70.72809]
Q = 14(5.65) + 4.88(15)(3.98)
Q = 79.19 + 291.608
Q = 370.80

Therefore, the quantity of heat loss is 370.80 J/Kg K.
