QUESTION ONE: $(30$ marks$)$

Air at $15C$ and $1$ atm flows with a velocity of $8\frac{m}{s}$ past a flat plate which is maintained at a uniform temperature of $115C.$ Calculate:

i$)$ Thickness of the boundary layer $0\mathrm{.}6$ m from the leading edge

$(9$ marks$)$

ii$)$ The position of the point of transition to turbulent flow.

$(4$ marks$)$

iii$)$ The total drag force on one side of the plate, per metre width of the plate, over the first $0\mathrm{.}6$ m $.$

$(7$ marks$)$

iv$)$ The heat transfer coefficient $0\mathrm{.}6$ m from the leading edge of the plate.

$(7$ marks$)$

v$)$ The rate of heat transfer from one side of the plate to the air, per metre width of the plate, over the first $0\mathrm{.}6$ m $.$
