Question

Question 5 (5marks) In the answer booklet indicate if the following statements are TRUE or FALSE (a) Repeated measurements can be used to reduce the uncertainty in the mean of the measured quantity. (b) Turbulent boundary layers are more resistant to separation than laminar boundary layers. (c) Pumps with backwards facing blades are at a higher risk of becoming unstable (hunting for operating speed). (d) The effect of heating on the speed of a compressible flow is independent of Mach number. (e) The flow downstream of a moving normal shock wave is always subsonic in the shock-fixed reference frame.
