Water enters a mixing device at 150 L/s through pipe A, while oil of S.G. 0.8 is forced in at 30 L/s through a pipe B. If the liquids are incompressible and form a homogenous mixture, determine the average velocity and mass density of the mixture leaving through a pipe C of diameter 30 cm. Assume that there is no chemical reaction with the oil and water and that the mixture is incompressible.

A chamber is filled with a gas that has a pressure of 0.250 atm and ???is connected to a mercury-filled u-tube with a width of 0.01m. The left side of the tube is closed and there is a vacuum at the top of the tube. How much higher is the mercury on the left-hand side compared to the right-hand side?
An aquatic organism needs to be neutrally buoyant to stay at a constant depth. Fish accomplish this with an internal swim bladder they can fill with air that they take in from the water through their gills. One complication is that the pressure in the swim bladder matches that of the surrounding water, but the water pressure changes with depth. Because the volume of a gas is inversely proportional to pressure (as you may already know if you have studied the ideal-gas law), the volume of air in a fish's swim bladder decreases with depth unless the fish actively adds more air.

Bacteria have a density that is about the same as water. Their average velocity is 10^-3 m/s. A bacterium with a radius of 1 um should have a diffusion coefficient of about 2.2x10^-13 m^2/s. (a) Find the random-walk step size (b) How long does it take for an average walk to reach 1 mm in seconds and days? Note that we are considering the diffusion away from the starting point and are calculating the distance through three dimensions. Show your work
