Learn How to Calculate Arithmetic Mean Temperature Difference - Tutorial

Definition:

Arithmetic Mean Temperature Difference is the difference between the average temperatures of hot and cold fluids. This method is used to understand heat transfer in systems such as heat exchangers.

Example :

Given,

HT_s = 60HT_e = 80CT_s = 0CT_e = 20

To Find,

Arithmetic Mean Temperature Difference

Solution:

Substitute the values of HTs, HTe and CTs, CTe in the above formula AMTD = ((HT_s + HT_e)/2) - ((CT_s + CT_e) /2) = ((60+80)/2) - ((0+20)/2) = (140/2) - (20/2) = 70 - 10 = 60 °C
