Viking Vessel Company manufacturers cylindrical gas storage tanks. The company foresees a market for nominal 100-ft3 tanks of varying proportions. The tanks are to be rated at 60 psi. Viking uses steel with an allowable tensile stress of 15,000 psi. Welded joints are fully inspected, and a 100% joint efficiency may be assumed.
Write a program that will generate a table of required wall thicknesses for tanks that have length-to-diameter ratios ranging (approximately) from 1.0 to 4.0. Diameters are to be in 2-in. increments. Lengths should be rounded up to the next 2-in. increment so that the volume of the tank is 100 ft3, minimum. The output should be a list showing diameter, length, volume, and required wall thickness. (The thickness may be rounded up to 0.01 in.)
