Question

A wall of length "L" m and height "H" m is made from a thick bricklayer of 38 cm with thermal conductivity of  0.57 W/mK is subjected to heat transfer due to the outside temperature as 35 oC and inside temperature 28 oC.  If the energy loss is 10465 kJ in 11 hours. 

Determine the Heat transfer rate, Surface Area and Length and Height of the wall, if L = 3.5 H.

Solution:

i) Heat Transfer Rate (in Joule/Sec) = 

ii) Surface Area of the Wall (in m2) = 

iii) Height of the Wall (H in m) = 

iv) Length of the Wall (L in m) =
