Calculate the pressure drop to process pregelatinized starch

Reference no: EM13313937

A single screw extruder is being used to process pregelatinized starch. The screw dimensions are as follows: channel width 3 cm, channel height 0.5 cm and screw length 50 cm. The wall velocity is estimated to be 0.31 m/s. The consistency coefficient is 3300 Pa sn and the fl ow behavior index is 0.5. A mass flow rate of 91 kg/hr is desired. The density is 1200 kg/m3. Calculate the pressure drop.
