a Air flows through a packed bed plug flow reactor. The mass flow rate is 110 lb/h and the entering pressure atm. The tube has a diameter of 0.138233 ft and a length of 70 ft. The reactor is packed with a catalyst of 0.03 ft diameter and the void fraction is 45%. Assuming a constant temperature and constant prope the air. The density and viscosity of the air are 0.555 lb/ft and 0.0666 lb/ft.h, respectively, Calculate the following: 1- The exit pressure (atm) 2.
