Aproduct designer for a range of nautical safety devices conceives of a floating container in which emergency supplies can be
stored, which would automatically become detached from a boat
if it sunk. the container is to be a cylinder with a radius of 20 cm
and a height of 1 m. when in the water 20% of the volume of the
container must be above the surface. the container is attached to
the deck of the boat by a cord which should break as the boat sinks
and the container is submerged and pushed upwards by it’s own
buoyancy.
(a) what is the maximum mass of the container and it’s contents?
(b) at what tension should the cord attaching the container to
the boat break?

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.
