Power is the a. rate of energy delivery (work done per second) b. amount of energy available c. capacity to do work (force over distance) d. combination of the rate of energy delivery, amount of energy available, and the capacity to do work e. amount of work done when a force of one newton is exerted over one meter

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.
