Copper spheres of 20-mm diameter are quenched by being dropped into a tank of water that is maintained at 280 k. the spheres may be assumed to reach the terminal velocity on impact and to drop freely through nitrogen collection chamber nitrogen nozzle molten solder pot volume piezoelectric oscillator v, t[infinity] = 30°c dp = 130 m the water. estimate the terminal velocity by equating the drag and gravitational forces acting on the sphere. what is the approximate height of the water tank needed to cool the spheres from an initial temperature of 360 k to a center temperature of 320 k?
