chemical reaction engineering

A chemical industry in Muscat producing a product B as per the following homogenous gas phase second orders reaction, A----3R. The feed is entering at a rate of 4 m/h of pure A at 623 K and 5 atm The experimental reactor having a size of 25 mm internal diameter and 2m length given 60% conversion of A A commercial plant is to handle 320 m/h of feed containing 80....% A and -20. mole% inerts 350 C and 25 atm for obtaining 80% conversion of A (Assume: Plug flow reactor and ideal gas behavior) at (1) Calculate the volume of reactor for both experimental and commercial reactor [6 mark] (ii) Calculate the no. of lengths of 25 mm ID x 2 m length pipe that are needed for 80% conversion [6 mark] (iii) Calculate the number of pipe (Similar to specification of Q(iii)] by graphical method for commercial plant(attach the graph sheet) [6 mark) (iv) Should they (pipe length) be arranged in parallel or in series? Give reason [2 mark]
