The feed to an ammonia synthesis reactor contains 25 mole % nitrogen and the balance hydrogen. Calculate the mass of the feed containing 1235kg nitrogeb.

A mention is basic units of ` a ^ 3 , : b' and 'R' of Vander Waals equation of state (p + (a * n ^ 2)/(p ^ 2)) (V-n overline D )= nRT Where P is pressure, V = Volume R = Gas Constant, T = Temparature N = Number of moles and the equation is consistent in unit.

A 37 wt % hydrochloric acid solution (sp. Gr = 1.19 ) flows through a 40m long and 8 cm diameter pipe at a rate of 90 1/min. How long would it take to fill a drum with the solution which contains 180 mole of HCI ?
