A steel drill rod that is 10 mm in diameter and 20 cm long is
being heat treated in an oil bath. The 1050°C rod is quenched and
held at 700°C and then quenched a second time to 30°C. Calculate
the quantities of heat that must be removed at the two quenching
stages. Weight density of steel as ρw = 76 kN/m3 , The specific
heat of steel is c= 0.50 kJ/(kg . ºC).

A rod of diameter D = 25 mm and thermal conductivity of 60 W/m·K
protrudes from a furnace with a wall temperature of 200ºC. The rod
is welded to the furnace wall and is used as a hangar for
instrumentation cables. To avoid damaging the cables, the surface
temperature of last 100 mm of the rod must be kept below 100ºC. The
ambient air temperature is 25ºC and the convection coefficient is
15 W/m2K. (a) Write the finite-difference equation for...
