please answer with full steps and needed charts

You have designed a sieve tray column with 12 in tray spacing to operate at a pressure of 2 atm and 75% of the flooding velocity. The value of the flow parameter is Fr=0.7, and the flooding velocity is uflood = 1.83 ft/s. The feed is saturated vapor that is 60 mol% methanol. Assuming separation is essentially complete and LIV = 0.6, estimate the column diameter required at the top using n = 0.90. Assumptions: idea gas; ignore the effect of temperature change on calculation of pr. Methanol boiling point = 337.7 K, R = 8.2057 x 10-m'atm/K mol. Hint: LG remains constant. MW = 32.04 g/mol N = 12
