Calculate the heat flux (in w/m^2) through a sheet of a metal 14 mm thick if the temperatures at the two faces are 350 and 140°c. assume steady-state heat flow and that the thermal conductivity of this metal is 52.4 w/m-k. (b) what is the heat loss per hour (in j/h) if the area of the sheet is 0.42 m2? (c) what will be the heat loss per hour (in j/h) if a material with a thermal conductivity of 1.8 w/m-k is used? (d) calculate the heat loss per hour (in j/h) if the first metal is used and the thickness is increased to 24 mm.
