You are asked to design piping systems of two different lengths of 0.75 and 1 km respectively for the pneumatic transport of solids at the rate of 20 tons/day. Particles sizes of different solid particles are given in Table 1. Using typical solid to gas mass ratio of 5 and air flow rate of 35 m/s to avoid excessive pressure drops, estimate the air flow requirements, the pipe diameters and the pressure drops in the pipeline for transporting various solid materials. State your assumptions, if any. Briefly comment on your results in terms of the energy requirements for handling various types of solids for three piping systems and summarize your results in tabulated form

You are asked to design piping systems of two different lengths of 0.75 and 1 km respectively
for the pneunatic transport of solids at the rate of 20 tons/day. Particles sizes of different solid
particles are given in Table 1.
Using typical solid to gas mass ratio of 5 and air flow rate of 35 m's to avoid excessive pressure
drops, estimate the air flow requirements, the pipe diameters and the pressure drops in the
pipeline for transporting various solid materials. State your assumptions, if any.
Briefly comment on your results in terms of the energy requirements for handling various types
of solids for three piping systems and summarize your results in tabulated form.
