h=20 W/noc resistance heater Problem 1 (20 points) A rectangular plate lm by lm and thickness of 4mm is heated by a resistance wire from one side and is exposed to the atmosphere (with a convective heat transfer coefficient of 20W/m2.°C) on the other side. The plate is made of aluminum (check for the T-25°C properties online and quote your source) The power input to the resistance wire is 1kW. If the plate is initially in thermal equilibrium with the atmosphere at 25°C, calculate the temperature of the plate after 2 minutes. Clearly state all assumptions made. You must derive the relevant equations from the basic conservation of energy principle. im Himmt
