In the free convection regime of pool boiling, the heat flux is proportional to__________________?
Correct answer: B. Δt5/4
- A. Δt1/2
- B. Δt5/4
- C. Δt2
- D. Δt
Explanation
In the free-convection region before vigorous nucleate boiling, the pool-boiling heat flux varies approximately as the temperature excess raised to the 5/4 power. The higher powers associated with nucleate boiling do not apply in this regime.
