Heat is transferred by conduction through a wall of thickness 0.87 m. what is the rate of heat transfer if the walls thermal conductivity is 13 w/m-k, the surface area is 5 m2, and the surface temperatures are 14 °c and 93 °c. report your answer in watts.

Explanation:

The given data is as follows.

         Thickness (dx) = 0.87 m,       thermal conductivity (k) = 13 W/m-K

        Surface area (A) = 5 ,      

According to Fourier's law,

                    Q =

Hence, putting the given values into the above formula as follows.

                      Q =

                          =

                          = 5902.298 W

Therefore, we can conclude that the rate of heat transfer is 5902.298 W.

the correct answer is answer a. a mixture

no other options make sense

hope this

have a great day : )

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.
