For computer chip of 10mm (length), 5 mm(width) is operated by power of 0.645 watt, which surrounded by coolant material of temp of 80 F. Find the Surface Temperature in K of the computer chip during the heat transfer of convection. Assuming no KE energy is changed. The Internal energy is 3.5J/sec and PE=2.5J/s (Hints:heat convection, Q= hAdt, heat transfer coefficient , h=150 W/sq.m K, W=J/sec, Apply 1st law of Thermodynamics)
