221. Velocity profiles are measured at the upstream end (surface 1) and at the downstream end (surface 2) of a rectangular control volume, as shown in Fig. P2.21. If the flow is incompress- ible, two dimensional, and steady, what is the drag coefficient for the airfoil? The vertical di- mension H is 0.025c. The pressure is poo (a constant) over the entire surface of the control volume. (This is an extension of Problem 2.9.) 3)-r u=U, H 0.02501 Figure P2.21

3. Velocity profiles are measured at the upstream end (surface I) and at the downstream end (surface 2) of the control volume shown in figure below. Surfaces 3 and 4 are streamlines. If the flow is incompressible, two dimensional, and steady, what is the drag coefficient for the airfoil? The vertical dimension Hp = 0.025c. The pressure is Pao (a constant) over the entire surface of the control volume. Streamline (--v-(1-05000 )

just now i sent this questions.
this is the answer given. however the answer i afraid
that he used formula that is not for constant surface temperature
and noncircular formula.
this is the formula foe the noncircular tube. because
the question ask about triangle.
my problem is, i cannot answer question 1(b) that ask
the heat transfer coefficient, h. please help me. thank you.
