Question

< 5 | 트 Lm 3 points An orange painted electrical heater containing a 0.51 m long, 1.7 cm diameter electrical heating element is being used to warm a room. Heat is generated by the element as a result of electrical resistance, and the surface of the heating element is measured to be 166 °C when in steady operation. In this case, the value for the heat transfer coefficient, h, was determined to be 14 W m²¹ K-¹. Determine the rate of heat transfer from the heating element to the surrounding fluid (air) when the room temperature is 17 °C Report your answer in Watts to 2 decimal places. > P
