Assignment Help Mechanical Engineering
##### Reference no: EM13713180

For spherical sand particles with Dp = 0.045 inches and the density of each particle is 145 lbm/ft3, estimate the minimum fluidizing velocity for air and for water. Assume a porosity of 32 percent. You may need to rederive Equation 11.41 considering the non-negligible density of the fluid - in the case of water. Assume a temperature 68 °F.
