please show all steps :)

A single compartment baghouse is to be applied to a process that has a geometric mass mean diameter of 5m, a dust of loading of 1.5gr/cf, and a particle density of 4.5g/cm3. The air/cloth ratio is 2.5fpm, the residual pressure drop is 3 in. H2O, and the temperature is 130C. Determine the maximum filtration time that can be used if the maximum pressure drop is limited to 8 in. H2O
