Question

A wall of length "L" m and height "H" m is made from a thick bricklayer of 20 cm with thermal conductivity of  0.59 W/mK is subjected to heat transfer due to the outside temperature as 38 oC and inside temperature 24 oC.  If the energy loss is 12867 kJ in 9 hours. 

Determine the Heat transfer rate, Surface Area and Length and Height of the wall, if L = 2 H.

Solution:

  1.  Heat Transfer Rate (in Joule/Sec) = 
  2.  Surface Area of the Wall (in m2) =
  3.  Height of the Wall (H in m) = 
  4.  Length of the Wall (L in m) =
