: A cylinder with a diameter of 0.1 m and a length of 1 m is exposed to a fluid flowing at a velocity of 10 m/s. The fluid has a temperature of 50°C and a kinematic viscosity of 2 × 10^(-5) m^2/s. Calculate the heat transfer coefficient and the Nusselt number.
The heat transfer coefficient can be calculated as: : A cylinder with a diameter of 0
Since the Reynolds number is greater than 10^4, the flow is turbulent. Using the correlation for turbulent flow over a cylinder, we can calculate the Nusselt number: The heat transfer coefficient can be calculated as:
: Using the solution manual, we can find the solution to this problem. First, we calculate the Reynolds number: : A cylinder with a diameter of 0
Re = ρUD/μ = (1000 kg/m^3 × 10 m/s × 0.1 m) / (2 × 10^(-5) kg/m·s) = 50,000
