2. Say we need to have honey (viscosity 100 cp) flowing in a tube at 10 liter/min. Density is 1200 kg/m³. For reasons of product quality, we do not want it to go into turbulent flow. (This is a real thing with some biological fluids.. turbulence can "damage" the fluid.) What diameter (minimum) is required. Would you actually design for this diameter ... or what would you actually recommend? b. What pressure drop would be required per meter of tubing if we used a diameter 20% larger than required?
