Answer to Question #160414 in Physical Chemistry for deepak

Question

In order to increase productivity, 40% more blast is injected in BF per unit time (base case at 2400 Nm3 /m2 /hr, average pressure at 1.8 atm and pressure drop of 1.4 atm). To restrict channelling, it is intended to maintain the pressure drop and hence linear velocity of gas through BF to be constant by enhancing top pressure. What will be the bottom pressure to achieve this? Assume, velocity exponent for pressure drop is at 1.75.
