Calculate the pressure drop over a 100m length due to friction when a slurry made from 1.0-mm silica particles is pumped through a horizontal 6-cm diameter pipeline (smooth pipe) at 2.5 m/s. the slurry contains 25 per cent silica by volume. the density of silica is 2700 kg/mº, pw = 1000 kg/mº, mw=0.001 kg/ms. use a value of 82 for 2. drag coefficient for these particles, cp, may be taken as 0.44.
