In plating a continuous strip of steel 0.9 m wide with Sn from an acid solution (valence charge=2), the desired strip speed is 500 m/min., current efficiency is 100%, and the thickness of tin plate is to be 0.4 μm (on each side) at a current density of 5000 A/m2. How long must the plating tank be assuming that the strip passes straight through the tank with no returns or bends? (density of Sn=7.31 g/cc, atomic weight of Sn=118.7).

An insulated tank truck containing 50,000 pounds of double-distilled, deionized water at 30 °c is pumped into a closed, refrigerated storage tank maintained at 5 °c in a facility located on top of mount mitchell, north carolina (elevation 6,684 feet & average july temperature of 84 °f). a)-determine the volume of the storage tank required to hold the purified water. b)- determine the initial and final pressure differences that must be overcome by a liquid pump assuming the storage tank initially contains air at 5 °c. assume the air is slowly bled out of the storage tank during the water transfer c.) during a routine operation today, the tank is slightly ruptured by a stainless steel pipe and a water acrosol of droplets begins to spray out of the storage tank. state all assumptions and determine the internal pressure within the water droplets produced
