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 × 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
Nu = 0.664 × Re^0.5 × Pr^0.33 = 0.664 × (333,333)^0.5 × 2.58^0.33 = 250.3 Calculate the heat transfer coefficient and the Nusselt
: A flat plate is maintained at a temperature of 80°C and is exposed to a fluid flowing at a velocity of 5 m/s. The fluid has a temperature of 20°C and a kinematic viscosity of 1.5 × 10^(-5) m^2/s. Calculate the heat transfer coefficient and the Nusselt number. Re = ρUD/μ = (1000 kg/m^3 × 10 m/s × 0
Nu = 0.026 × Re^0.8 × Pr^0.33 = 0.026 × (50,000)^0.8 × 2.58^0.33 = 421.1
The heat transfer coefficient can be calculated as:
