Question

Problem 8 Situation: A packed bed is composed of crushed rock with a density of 175 lb/ft3 of such a size and shape that the average ratio of surface area to volume for the particles is 50 [in2/in3]. The bed is 6-(ftl- deep, has a porosity of0.3, and is covered by a 2 [ftl deep layer of water that drainsby gravity through the bed. Assume that it exits the bed at atmospheric pressure. Requirements: Calculate the flow rate of water through the bed in
