4. A solid copper ball with a diameter of 3.0000m at sea level is placed on the bottom of the ocean, at a depth of 10.0km. If the density of sea water is 1.03 x 103 kgm"3, how much does the diameter of the ball decrease when it reaches the bottom? The bulk modulus of copper is 14 x 1010Pa.
Following the stream cross section (ft2) and the stream velocity (ft/sec) allows us to calculate the stream flow (ft3/sec). The watershed runoff during a storm is 3.5 ft. high and flows in 18 ft. wide channel. The velocity is measured at 1.2 feet per second (fps). What is the flow rate of the water in cubic feet per second?

The process in question uses a centrifugal fan pump to convey a 1000 gallon per minute flow containing 2% finely ground wood pulp to a head box...which in turn is supposed to ocnvert turbulent flow to laminar flow and then deposit the water & pulp slurry on a high speed moving wire in order to form a wet fiber mat. However, t
You have a liquid sitting between 2 plates. A shear stress is applied to the top plate causing it to move. (the bottom plate is rigid) This fluid has a yield stress (ty) bellow which it will not move. Assume that the liquid, where in contact with the plate, moves at the same velocity as the plate. Also assume that the fluid h
