it is a question! answer completely

To what temperature in C) must a cylindrical rod of one metal 10.090 mm in diameter and a plate of second metal having a circular hole 9.986 mm in diameter have to be heated for the rod to just fit into the hole? Assume that the initial temperature is 22C and that the linear expansion coefficient values for metals one and two are 4.1x10^rC) and 19x 10C, respectively (a) Calculate the heat flux in W/m) through a sheet of a metal 13.0 mm thick If the temperatures at the two faces are 319 and 138 C. Assume steady-state heat flow and that the thermal conductivity of this metalis 53.8 W/mK. W/m? (b) What is the heat loss per hour if the area of the sheet is 0.477 ms J/h (c) What will be the heat loss per hour if a material with a thermal conductivity of 1.73 W/m-K is used? a 1 J/h (d) Calculate the heat loss per hour if the first metal is used and the thickness is increased to 22.5 mm J/h
