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

Remember that pressure drop in piping vary as the diameter is changed, assuming the mass flow rate is the same. you found that pressure drop is inversely proportional to diameter to the fifth power. You also know that velocity in the duct/pipe is inversely proportional to area or diameter squared, again for the same mass flow rate. Your water flow analysis is based on achieving a water flow velocity similar to the air velocity (24 ft/s), however the result for...

Air Under standard conditions flows through a 4.0.mm diameter down tubing with an average velocity of V=50 m/s. For such conditions the flow would normally be turbulent. However, if precautions are taken to eliminate disturbance to the flow (the entrance to the tube is very smooth, the air is dust free, the tube does not vibrate, etc) it may be possible to maintain laminar flow. Find (a). Determine the pressure drop in 0.1.m section of the tube if the flow...
