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 37 degree C. Calculate h at the trailing edge (a) if the fluid is water; (b) if the fluid is glycerin (h = 34G W/m2K). (c) Compare the drag forces in the two cases. [There is 23.4 times as much drag in the glycerin.)
