A non-Newtonian soy flour extrudate with 25% moisture (wet basis) is being pumped through an extruder. The channel in the metering section has the following dimensions: width 5 cm, height 2 cm and length 50 cm. The properties of the extrudate are described by a consistency coefficient of 1210 Pa s^0.49 and density of 1100 Kg/m3. Estimate the pressure drop if the mass flow rate of 600 Kg/hr is to be maintained and the wall velocity is 0.3 m/s
