Consider atmospheric air at 25oC in parallel flow at 4 m/s over both surfaces of a 1-m long flatplate maintained at 75oC. (a) Determine the velocity boundary layer thickness, the surface shear stress, and the heat flux at the trailing edge. (b) Determine the drag force on the plate and the total heat transfer from the plate, each per unit width of the plate. (c)Plot each parameter of part (a) as a function of distance from the leading edge of the plate.

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.6 m below the tank bottom which is a = 6.7 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute). report your answer in meters to two decimal places.
