3. An incompressible, viscous fluid with density, p, flows past a solid flat plate which has a depth, b, into the page. The flow initially has a uniform velocity U., before contacting the plate. After contact with the plate at a distance x downstream from the leading edge, the flow velocity profile is altered due to the no-slip condition. The velocity profile at location x is approximated to have a linear shape, u = U. z for y s 8...

Problem 4 Air at 100 C flows across a thin, flat plate of subliming naphthalene that is 3.4 m long. The Reynolds number at the trailing edge of the plate is at the upper limit for a laminar boundary layer (Re 5e5). Estimate: (a) the average rate of sublimation in kmol/s*m2; and (b) the local rate of sublimation 0.5 m from the leading edge. Vapor pressure of naphthalene = 10 torr viscosity of air 0.0215 cP; molar density of air...
