Air enters a 7-cm-diameter and 5-m-long tube at 65°C and leaves at 15°C. The tube is observed to be nearly isothermal at 5°C. If the average convection heat transfer coefficient is 20 W/m2.°C, determine the rate of heat transfer from the air. (Solve using EES, and round the answer to 2 decimal places.)

![Air enters a 7-cm-diameter and 5-m-long tube at 65°C and leaves at 15°C. The
tube is observed to be nearly isothermal at 5°C. If the average convection heat
transfer coefficient is 20 W/m2.°C, determine the rate of heat transfer from the
air. (Solve using EES, and round the answer to 2 decimal places.)
The rate of heat transfer from the air is

Follow-up Question
Your solution is incorrect. It says the answer is NOT 491W or 1099W (see attached photo). Pleas provide the correct answer. Thank you.
![Air enters a 7-cm-diameter and 5-m-long tube at 65°C and leaves at 15°C. The tube is observed to be nearly isothermal at 5°C. If the average convection heat transfer coefficient is 20 W/m²·°C, determine the rate of heat transfer from the air. (Solve using EES, and round the answer to 2 decimal places.)
The rate of heat transfer from the air is 1099 W.

**Explanation for Educational Website:**
In this problem, we analyze the heat transfer process of air as it passes through a tube. The tube's dimensions and temperatures are provided, along with the convection heat transfer coefficient. These parameters help us determine the amount of heat energy transferred from the air by employing appropriate heat transfer equations and computational tools like EES (Engineering Equation Solver). The result of this calculation is expressed in watts (W), indicating the rate at which heat is being transferred.](https://content.bartleby.com/qna-images/question/fb9a7c18-65f1-48ed-bb7e-4937a04e4157/6e69142f-b13b-4b1c-9fbb-101e661fae5f/4i1vviu_thumbnail.png)
