Please help me solve

I. (25 points) A rod having a diameter of 2 cm and a length of 10 cm has one end maintained at 200 oc and is exposed to a convection environment at 25 oc with h=40 W/m20C. The rod generates heat internally at the rate of 50 W/m3 and the thermal conductivity is 35 W/m0C. If Tl = 131C, T3- 113C, T4 102.5C, find Tl and T5. Show your work and use control volumes. h=40 W/m2OC 9 Ax = 2 cm 2 cm
