Drag measurements were taken for a 5 cm diameter sphere in water at 20 °C to predict the drag force of a 1 m diameter balloon rising in air with standard temperature and pressure. Given kinematic viscosity of water (v) = 1.0 X 10-6 m2/s and kinematic viscosity of air (v) = 1.46 X 10-5 m2/s. Determine the sphere velocity if the balloon was rising at 3 m/s

A can of soft drink, 12-cm high and 6-cm diameter, is initially at 20°C. It is placed in a refrigerator where the air is at 0°C. The convective heat transfer coefficient associated with the outer surface of the can is 10 W/m2 °C. Assuming the properties of the drink to be those of water and that the heat capacity of the container is negligible, estimate the time taken for the temperature of the drink to reach 5°C.
