Air at 295 K flows at 3 m/s over a flat plate at 390 K. The air properties are as follows: density =1.1 kg/m3, viscosity =18.1×10−6 Pa.s, specific heat capacity =1005 J/kgK, and thermal conductivity =0.024 W/mK. The velocity and temperature profiles are assumed to be linear, giving the local Nusselt number to be Nux = 0.289 Rex1/ 2Pr1/3. The flow will become turbulent at a Reynolds number of 5×105. Assume the width of the plate perpendicular to the air flow is 1 m. At what distance from the leading edge does the flow become turbulent? ________m What is the heat transfer at the point of transition? ___________W What is the total heat transfer along the length of the plate where the flow is laminar? __________W

A stream of Air flows over the upper surface of a flat plate having a length of 10 m. Variation of temperatures measurements in the boundary layer is correlated by an expression of the form T = 785 + 50 exp (-712xy), where x and y are in meters and T in K. The thermal conductivity of air is evaluated at the arithmetic mean of the free stream and surface temperatures to be k = 0.03 W/m.K. If the air temperature is equal to 45 C and the temperature of the plate is equal to 105 C. Determine The average convection coefficient for the entire plate.
