Question

Problem 3: In a certain pharmaceutical process, castor oil at 30 °C flows over a flat plate at 8 cm/s. The plate is 5m long and is heated uniformly and maintained at a surface temperature of 90 °C. Calculate (a) velocity and thermal boundary layer thickness at the trailing edge, (b) local dimensionless heat transfer coefficient, (c) total heat flux from the surface of the plate per unit width, and (d) Drag force on the plate. $\rho=956.8 Kg/m^3$, $\alpha = 0.65 \times 10^{-4} m^2/s$, $\nu= 7.2 \times 10^{-5} m^2/s$, $K=0.213 W/mK$. (4+2+2+2=10 Points)
