a) Estimate the pounds of mercury (Hg) it would take to fill a standard 5-gallon bucket you might buy at Lowes or Home Depot. List all assumptions and show all calculations. b) A helium-filled blimp is used at various athletic events. Determine the number of pounds of helium within it if its volume is 68,000 ft^3 and the temperature and pressure are 80 F and 14.2 psia (pounds per square inch absolute pressure), respectively. c) A 10 kg block slides down a smooth inclined surface as shown below. Determine the terminal velocity of the block if the 0.1-mm gap between the block and the surface contains SAE 30 oil at 60 F. Assume the velocity distribution in the gap is linear, and the area of the block in contact with the oil is 0.1m^2
