Gas with a density of 1.2 kg/m³ and viscosity of 1.05 × 10-5 Pa.s is injected into the pipe with a banana puree. The banana puree has a density 1030 kg/m³ and flows at a steady state with a mean linear velocity of 0.75 m/s through a tube 17.4 m long with an inside diameter of 0.085 m. The puree is a power law fluid with rheological properties of k = 6.51 Pa-s and the flow behavior index on n = 0.458. The mass flowrate of the gas is 12 kg/h, the gas is introduced into the pipeline at 20°C and at a pressure of 1.2 bar.
