Question

What is the equation of thermal conductivity for series connection?

Answer 1

Answer:

The heat current going through the first rod is H1=T1−T2R1 H 1 = T 1 − T 2 R 1 and that through the second rod is, H2=T1−T2R2 H 2 = T 1 − T 2 R 2 Total heat current going through left end is H=H1+H2=(T1−T2)(1R1+1R2) H = H 1 + H 2 = ( T 1 − T 2 ) ( 1 R 1 + 1 R 2 ) or, H=T1−T2R H = T 1 − T 2 R where, 1R=1R1+1R2 1 R = 1 R ...

Answer 2

Hey mate

K = (QL)/(AΔT)

K is the thermal conductivity in W/m.K. Q is the amount of heat transferred through the material in Joules/second or Watts. L is the distance between the two isothermal planes. A is the area of the surface in square meters.
