A thin plate is suspended in air at 1 atm. with T_infinite= 15°C. Air flows on both sides of the plate where the bottom side absorbs a uniform radiative heat flux of 1542 W/m2. The plate is oriented parallel to the flow and the length along the flow direction is 60 cm. Consider the plate is negligibly thin and the width of the plate (perpendicular to the flow) is large, so that the problem can be considered as a 2D...

1.7 kg/s NH3 and 20 m3/s air at 25 oC and 1 atm are fed into a reactor in which the ammonia is completely consumed. The product gas emerges at 300 oC. Calculate the rate at which heat must be transferred to or from the reactor, assuming operation at approximately 1 atm. You must show full systematic working. The standard heat of reaction for the oxidation of ammonia is given below: 4 NH3(g) + 5 O2(g) ? 4 NO(g) +...

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...
