The rate of heat generation in the solid rod is given by \(\rm \dot{q}=\dot{q}_0\left[1-\left(\frac{r}{R}\right)^2\right]~\) W/m3. Where R is radius & q0 is constant whose value is 5.25 × 106 W/m3. Find the temperature at the surface of the rod (in °C) if the diameter of the rod is 20 mm. The surrounding medium is at 25°C with a heat transfer coefficient of 120 W/m2k. (correct up to 2 decimal places)
Enter numerical value using the virtual keypad. Round off where necessary.
