Choose one of the three light technologies (fiber optics, lasers, and holograms), and research it. Write a one or two-page report. You could include more details about how the technology works, a particular use for the technology, or how it was discovered. PLZ HELP THIS IS DUE TODAY!!!

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.
