Glycerin is poured into an open u-shaped tube until the height in both sides is 20cm. ethyl alcohol is then poured into one arm until the height of the alcohol column is 20cm. the two liquids do not mix. what is the difference in height between the top surface of the glycerin and the top surface of the alcohol?

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
