numerical-results-of-the-blasius-solution-to-the-prandtl-boundary-layer-equations-are-presented-in-t

Numerical results of the Blasius solution to the Prandtl boundary-layer equations are presented in Table $9.1 .$ Consider steady, incompressible flow of standard air over a flat plate at freestream speed $U=5 \mathrm{m} / \mathrm{s}$. At $x=20 \mathrm{cm},$ estimate the distance from the surface at which $u=0.95 U$. Evaluate the slope of the streamline through this point. Obtain an algebraic expression for the local skin friction, $\tau_{w}(x)$. Obtain an algebraic expression for the total skin friction drag force on the plate. Evaluate the momentum thickness at $L=1 \mathrm{m}$.

Circular cross-section studs of radius 10 mm, fixed length 100 mm, thermal conductivity 24 W/m K are attached to flat surface with their axes perpendicular to the surface on a square pitch of 30 mm. The primary surface is at 300 0C. A fluid at 50 0C is forced across the surface such that the mean heat transfer coefficient is 100 W/m2 K. Calculate the rate of heat loss per unit area of the studded surface. Assume that the heat transfer coefficient is the same for the primary surface and for the rod surfaces.

A plane surface 25 cm wide has its temperature maintained at 80°C. Atmospheric air at 25°C flows parallel to the surface with a velocity of 2.8 m/s. Using the results of boundary layer analysis, determine the following for a 1-m long plate: a. The mean coefficient of skin friction, Cf b. The total drag force exerted on the plate by the air flow c. The total heat-transfer rate from the plate to the air stream

00:01 In this question you have to find the point at which u equals 0 .95 capital u and slope of steam line divided by the x and the expression for the skin coefficient and the total drag and momentum thickness.
00:22 So first from the basic equation of lazier's solution we can find that if that equals u.
00:32 U is 0 .9130 at eta equals 3 .5 and fd that will be 0 .95 and eta equals 0 .95 at eta equals 4 so if we want if that equals 0 .95 and have that will be 3 .5 plus 4 4 minus 3 .5 divided by 0 .955 minus 0 .913 times .95 minus 0 .913, eta.
01:25 And that is 3 .94 for eta...
