Consider a fully developed laminar flow in a circular pipe of diameter 20 cm. The fluid has a thermal conductivity of 2.0 W/m-K. The Nusselt numbers for constant heat flux and constant wall temperature boundary conditions are 4.36 and 3.66 respectively. Calculate the heat transfer coefficients for these two boundary conditions.
- 143.6 W/m2K for both cases
- 26.6 W/m2K for both cases
- 343.6 and 36.6 W/m2K✓
- 436.6 and 43.6 W/m2K
Correct answer
43.6 and 36.6 W/m2K
