At zero flow, the two tubes vibrate in phase with each other. When flow is introduced, the Coriolis forces cause the tubes to twist resulting in a phase shift. The time difference between the

info.mheducation.comPipe flow for transport of water, air or similar fluids is typically turbulent. Flow of highly viscous fluids, such as lubricating oils, is often laminar. Since density and viscosity are parameters in the Reynolds number, values for ρ and µ for the flowing fluid are needed for pipe flow calculations. Values of density and viscosity for water from
