1. A flow with a small viscosity but non-zero value may be treated as an inviscid flow if the velocity gradient is not very high. True or False?
2. The drag is solely due to the friction between the flow stream and the surface of a body immersed in the fluid. True or False?
3. In general, a turbulent flow will incur a lower frictional loss as compared to a laminar flow. True or False?
4. If the friction factor is smaller, the pressure drop in a pipe is always smaller. True or False?
5. The mechanism of the lift generation may be explained using the Bernoulli equation. True or False?
6. The roughness of a surface may affect the stability of a boundary layer. True or False?
7. Flow through a large body may be studied using a scaled down model provided that a similarity analysis is followed. True or False?
8. The boundary layer separation is independent of the shape of the body. True or False?
