Fig extracts raw material powder has been transported through pipeline using air at 40C and 1 atm. (0) Determine the density of figs, with valid reference. (ii) Determine the density and viscosity of air in the process, with valid reference. Determine the terminal velocity of the powder at the different diameter at sphericity of 0.6 Terminal velocity (m/s) Equivalent volume of sphere diameter (cm) 0.007 0.7 (iv) Comment on the effects of fig sizes during transportation
