3) (35 pts) There is a dual-media filter with 0.5 m of anthracite coal and 0.3 of sand. Other data for anthracite: specific gravity is 1.67, porosity is 0.5, deo grain size is 1.5 mm. Other data for sand: specific gravity is 2.65, porosity is 0.4, doo grain size is 0.9 mm. The water temperature is 200, so the mass density of water (p) is 998.2 kg/m' and the absolute viscosity is 1.002 x 103 kg/m-s. Assuming a 30% margin...

Question 1: A grain of sand (p 1690 kg/m3) that has a 1.5 mm diameter falls into a saltwater pond that is 12 m deep. The saltwater has a density of ?-1024 kg/m3 and a viscosity of ? = 0.960P. Calculate how much time (in seconds) it will take the sand grain to hit the bottom of the pond. Assume that the grain achieves its terminal velocity almost immediately after being dropped.

10,000 kg of sand with a mesh size of 0.2 mm are fluidized at 300°C and 10 atm pressure, in a cylindrical column of 1 m diameter. Given that the minimal porosity for fluidization is 0.5, and R = 0.082 atm.m3 /kmol.K, calculate: (a) The minimal height of fluidized bed, if the density of the particles is 3000 kg/m3 . (b) Pressure drop experienced by air when passing through the sand bed. (c) Minimal fluidization velocity, if the viscosity of...
