Storage is required for 35,000 kg of propane, received as a gas at I0(C and l (atm). Two proposals have been made:
(a) Store it as a gas at 10(C and 1(atm).
(b) Store it as a liquid in equilibrium with its vapor at 10(C and 6.294(atm). For this mode of storage, 90% of the tank volume is occupied by liquid.
Compare the two proposals, discussing pros and cons of each, Be quantitative where possible.
