2-B
В 31, т%3D
Numerically calculate the thickness 8 for K = 1000 s' and the shear stress for
x= 5 cm. Calculate the local heat flux exchanged between the fluid and the plate for
these values of x, K and T = 5 K, T, = - 5 K (the plate is heated to avoid icing on
the wall). Calculate the overall heat transfer rate exchanged by the plate of length
2L, = 10 cm and span length L. = 50 cm.
(b) Repeat the calculation by replacing B=-0.18. Calculate the boundary layer
thickness, wall shear stress, convective heat transfer coefficient, local heat
flux, and total heat transfer for x-5 cm.
