(b) A Newtonian liquid of viscosity 0.1 N s m2 is flowing through a pipe of 25 mm diameter and 20 m in length, and the pressure drop is 105 Nm2. As a result of a process change a small quantity of polymer is added to the liquid and this causes the liquid to exhibit non-Newtonian characteristics; its rheology is described adequately by the power-law model and the flow index is 0.33. The apparent viscosity of the modified fluid is...

UIT TULITE UTISVUUTTUM ransie Which is true about the liquid-gas interface (free surface)? Shear stress on the liquid side is equal (or almost equal) to that on the gas side. LO in Pressures on the liquid and gas sides are equal even with significant surface tension. In O Vertical speed on the liquid side is different from that on the gas side. When the gas viscosity is much smaller than the liquid viscosity, the velocity gradient on the gas side...
Liquid A is known to have a lower viscosity and lower vapor pressure than Liquid B. Use these facts to predict the result of each experiment in the table below, if you can. experiment predicted outcome F will be greater than FB 40.0 mL of Liquid A are poured into a beaker, and 40.0 mL of Liquid B are poured F will be less than FB into an identical beaker. Stirrers in each beaker are connected to motors, and the...
