A stick is a connection of two same -diameter metal rod 5 cm , and a length of both stick is 0,6m. The thermal conductivity of the first rod 92 cal /s.m.Β°C ,
and the second stick 50 cal / s.m.Β°C . The temperature at the free end of the first rod
100 Β°C and the free end of the second rod 0 Β°C , the temperature is kept constant .
Determine heat transfer within 5 minutes .
