Question $2$:

$(30$ marks$)$

Consider the following fluids at a film temperature of $300$ K in parallel flow over a flat plate with velocity of $1\frac{m}{s}$ : atmospheric air, water, engine oil, and mercury.

a$)$ For each fluid, determine the velocity and thermal boundary layer thicknesses at a distance of $40$ mm from the leading edge.

b$)$ For each of the prescribed fluids and on the same coordinates, plot the boundary layer thicknesses as a function of distance from the leading edge to a plate length of $40$ mm $.$

$($Hint: Use IHT software$/$MS Excel and the Bergman textbook$)$

Note: Take 'full screen' screenshots $($of the whole desktop screen showing everything including date and time on your desktop$)$ showing of your results in IHT software and paste it in your answer.
