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.
