The image above represents quantity of heat loss. To calculate 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(T1Â – T2)5/4Â + 4.88E[(T1Â + 273/100)4Â – (T2Â + 273/100)4]
Where:
Q = Quantity of Heat Loss
T1Â = Initial Temperature
T2Â = 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(T1Â – T2)5/4Â + 4.88E[(T1Â + 273/100)4Â – (T2Â + 273/100)4]
That is, Q = 14(21 – 17)5/4Â + 4.88(15)[(21 + 273/100)4Â – (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)
Then, Q = 79.19 + 291.608
Q = 370.80
Therefore, the quantity of heat loss is 370.80 J/Kg K.
