The lower half of a 7-m-high cylindrical container is filled with water (rho = 1000 kg/m3) and the upper half with oil that has a specific gravity of 0.85. Determine the pressure difference between the top and the bottom of the cylinder.

Now suppose one side of each pancake is burned. Describe an algorithm to sort an arbitrary stack of n pancakes, so that the burned side of every pancake is facing down, using O (n) flips.

The value of the critical Reynolds number for the flow over a flat plate is 5 x10^5. The significance of the value is: (a) The boundary layer will be turbulent where the Reynolds number is less than this value.
