A student team is to design a human-powered submarine for a design competition. The overall length of the prototype submarine is 4.85 m, and its student designers hope that it can travel fully submerged thropah water at 0.440 m/s. The water is freshwater (a lake) at a temperature, T= 15°C, p=999.1 kg/m³ and dynamic viscosity, µ = 1.138 x 10-3 kg/m's. The design team builds a one-fifth scale moder to test in their university's wind tunnel (Figure 10). A shield surrounds the drag balance strut so that the aerodynamic drag of the strut itself does not influence the measured drag. The air in the wind tunnel is at 25°C and at one standard atmosphere pressure having p = 1.184 kg/m³ and u = 1.849 x 10-5 kg/m's. Determine the air speed required to run the wind tunnel in order to achieve similarity. %3D %3D Wind tunnel test section Model FD V P P Strut Shield Drag balance Figure 10

Global warming will produce rising sea levels partly due to melting ice caps and partly due to the expansion of water as average ocean temperatures rise. To get some idea of the size of this effect, calculate the change in length, Ah (in mm), of a column of water 1.5 km high for a temperature increase of 1.2 °C.Assume the column is not free to expand sideways. As a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to the surface can expand sideways onto land, and only to a limited degree. As another approximation, neglect the fact that ocean warming is not uniform with depth. Properties of water: 3 = 210 x 10 /C. c= 4186 J/kg - °C, L; = 334 kJ/kg, Le = 2256 kJ/kg Enter you answer below (to the nearest mm): Ah (in mm) = Type your answer.
