Storage is required for 35,000kg of propane, received as a gas at 10C and 1(atm). Two proposals have been made: (a) Store it as a gas at 10C and 1(atm). (b) Store it as a liquid in equilibrium with its vapor at 10C and 6.294(atm). For this mode of storage, 90% of the tank volume is occupied by liquid. Compare the two proposals, discussing the pros and cons of each. Be quantitative where possible. One way is the compare the diameter of a spherical tank required in both cases
