Sparky is on the university speed ice skating team. When crossing the finish line Sparky wants to show off and come across the finish line on one skate with a velocity of 35 ft/sec (V). Sparky weighs 150 lbf. Sparky’s weight is supported by a thin liquid film of water melted by the pressure of the skate blade.

Your team is designing a chemical processing plant. You are the liquid handling and transportation specialist, and you need to transport a solvent (μ = 3.1 cP, ρ = 122k kg/m3) from a storage tank to a reaction vessel. Due to other equipment constraints, the fluid velocity must be 0.8 m/sec, and you must use stainless steel piping (ε = 0.00015 mm) with a total length (L) of 12 m. Determine the pipe inner diameter (ID) you will need to achieve a pressure drop of 0.3 kPa. Use the Moody chart.
