Two large fixed parallel planes are 12 mm apart. The space between the surfaces is filled with oil of viscosity (0.972 Pa.s). A flat thin plate 0.25 m² area moves through the oil at a velocity of 0.3 m/s.

Question 9 Consider the flow of water over a flat plate. In a different experiment consider the flow of air over a flat plate. In both cases the flow is steady, the boundary layers that are formed are laminar and the gravitational acceleration can be neglected. In both cases the velocity far from the plates is the same (v.) and the temperature is also the same (80 °F). For the same distance x from the leading edge, in which boundary layer will the friction coefficient be higher? (a) The friction coefficient is the same for both cases. (b) In water. (c) In air. (d) It depends on the velocity profile that is assumed inside the boundary layer.
Choose the most appropriate statement with respect to the pressure distribution of an airfoil. The flow velocities go to zero at the leading and trailing edge points. Upper and lower surface pressures are lower than under free-stream conditions. Upper and lower surface pressures are higher than under free-stream conditions. O Lift is the difference between the lower and upper surface pressures.
