It is desired to calculate the speed and the mass flow with which a puree of apple that is transported through a pipe of 15 cm of internal diameter, to a temperature of 25C. The total distance that the mash must travel is 300 meters, with between the points of departure and arrival a pressure drop of 250 kPa, being the point of arrival 5 meters above the starting point. At working temperature, the puree is still the power law, with a consistency index of 2.4 Pa sn and a behavior index at flow of 0.44, being its density 1200 kg/m3.
