You are working as an engineer at a food packaging plant. You have been assigned to work on a new packaging line for canned lemons. However, you know that lemons have a pH of 2.0. In one paragraph, using your own words, explain what this means, and what concept of chemistry leads you to believe that packaging lemons in cans might not be a good idea.

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.
