Question

Liquid at 23 degree C flows at 2 m/s over a smooth, sharp-edged, flat surface 12 cm in length which is kept at 57 degree C. Calculate h at the trailing edge (a) if the fluid is water; (b) if the fluid is glycerin (h = 346 W/m2K). (c) Compare the drag forces in the two cases. [There is 23.4 times as much drag in the glycerin.] Air at -10 degree C flows over a smooth, sharp-edged, almost-flat, aerodynamic surface at 240 km/hr. The surface is at 10 degree C. Find (a) the approximate location of the laminar turbulent transition; (b) the overall h- for a 2 m chord; (c) h at the trailing edge for a 2 m chord; (d) delta and h at the beginning of the transition region. [delta xt should be around half a millimeter.]

hey buddy .. Asking multiple questions in a single post is against the rules of cramster.. to which problem do you need solution?? choose either 6.15 or 6.16...
