consider the air flowing over a flat plate of length L=1m.
air's propertis
Density=1Kg/m^3
Cp=1000j/Kg*K
viscosity=10^-5Kg/m*s
k=0.1W/m*C

If length is 0.5m,
heat flux = 3000W/m^2
average heat flux =4500W/m^2

the plate temperature 20 degrees

(a) whay is flow?(Laminar or Turburlent of mixed)
(b) what is the possible range Air velocity?
(c) relationship Temperature air and Velocity air

Air flows over a 4 meter long flat plate at a velocity of 8 m/s. Using a spreadsheet, calculate the boundary layer thickness and wall shear stress at 0.1 meter intervals along the plate. Do not plot the wall shear stress at x=0. Use a transition Reynolds number of 5 x 10^5 . (You will need to calculate Rex at each location to determine if the laminar or turbulent correlations should be used.) Generate a spreadsheet table that includes columns...

Air at 25°C is flowing over 400°C hot iron ball with a velocity of 10 m/s. The diameter of the iron ball is 10 cm diameter and (p =7874 kg/m3 and cP = 450 J/kg.K). After a while the surface temperature of the ball drops to 300°C. Determine the average rate of heat transfer from the ball. How long will it take to drop from 400°C to 300°C. Calculate the drag force. (The surface of the ball is smooth.)
