Since the Reynolds number is less than 5 × 10^5, the flow is laminar. Using the correlation for laminar flow over a flat plate, we can calculate the Nusselt number:

Re = ρUD/μ = (1000 kg/m^3 × 10 m/s × 0.1 m) / (2 × 10^(-5) kg/m·s) = 50,000 Since the Reynolds number is less than 5

Nu = 0.664 × Re^0.5 × Pr^0.33 = 0.664 × (333,333)^0.5 × 2.58^0.33 = 250.3 Since the Reynolds number is less than 5

The heat transfer coefficient can be calculated as: Since the Reynolds number is less than 5

The heat transfer coefficient can be calculated as:

h = Nu × k/D = 421.1 × 0.025 W/m·K / 0.1 m = 105.3 W/m^2·K
