Convection
Ex. 3.15: air at 101.325 kPa and 308 K (35 °C) flows across a 50 mm diameter cylinder at a
velocity of 50 m/s. The cylinder surface is maintained at a temperature of 423 K (150 °C).
Estimate the heat loss per unit length of the cylinder.
Data: The physical properties of air at the film temperature of 365.5 K are:
H= 2.14 x 10-5 kg/(m-s), p = 0.966 kg/m³, k = 0.0312 W/(m-K) and Npr
0.695.
