ET / ENGINEERING / ChEE. 3. A vertical flash drum has been designed to flash a liquid feed ' F ' that contain 45 mol\% n-nonane (C9H20) and remaining is n-decane (C10H22) at 1atm. We need the vapor with 15kg/sec contains 81mol% n-nonane. Solution of the flash equation with equilibrium data gives Xnonane=0.21,Tdrum=380K. Take the molecular weight of n-decane and n-nonane as 142.29g/gmol and 128.2g/gmol respectively. The density of n-decane and n-nonane are 0.730g/cc and 0.718g/cc, respectively. The flow parameter constant, Flv=0.099 and Kdrum=274.32m/hr. Find (i) molar flow rate of feed. (ii) height of the flash drum
