Question

A fluid (Prandtl number, Pr=1Pr = 1) at 500 K500\text{ K} flows over a flat plate of 1.5 m1.5\text{ m} length, maintained at 300 K300\text{ K}. The velocity of the fluid is 10 m/s10\text{ m/s}. Assuming kinematic viscosity, ν=30×10−6 m2/s\nu = 30 \times 10^{-6}\text{ m}^2\text{/s}, the thermal boundary layer thickness (in mm) at 0.5 m0.5\text{ m} from the leading edge is __________
