A long cylindrical electric heating element (p = 2700 kg/m³, cp = 900 J/kg-K, k = 240 W/m- K) with diameter, D = 12 mm, experiences a cross flow at 30°C and 8 m/s. The power consumption per unit length of element for heating is 1000 W/m. Determine a.) the steady- state surface temperature (°C) and b.) the time required (min) to reach within 10° of this temperature if the rod was initially at 30°C.
