In a hypothetical scenario, the flow of oil over a surface can
be approximated as follows: u = 3y^2 m/s and v = 0 m/s. The
properties of the oil are: k = 0.145 W/m.K and μ = 0.8374 N.s/m2.
The viscous dissipation cannot be neglected. Also, all conditions
normalize to free stream conditions 2m above the plate (i.e.
velocity and temperature are constant beyond 2m). The free stream
temperature and the plate temperature are maintained at 25°C. If
the area of the surface is 0.5m2 , calculate the heat required to
maintain the surface at a constant temperature. You must clearly
indicate if this heat is supplied or taken away from the
surface.
