Question 3 a Determine whether the circular tank in the Fig. Q3(a) is filling or emptying, and at what rate the water level is rising or falling in the tank? (8 Marks) 0.85 m 3.2 m/s 15 cm dia. → 1.1 m/s 10 cm dial 2.5 m/s Figure Q3(a) b) Drag tests show that the drag force (F) on a square plate placed normal to the free-stream velocity is a function of the average velocity V, the density p, the plate length L. the viscosity u, the turbulence velocity u (m/s), and eddy length (m). By dimensional analysis, develop -groups that could be used to correlate the experimental results. Express your answer in a functional form F pV²1² -= f (1₂, 13,...... ... πn) (14 Marks) c) Explain the significance of the groups obtained in Q3(b) and how they influence drag force. (3 marks) 7 cm dia.
