Dimensionless numbers are useful tools to characterize, evaluate or identify the main phenomena occurring in a system. The Reynolds Number NRe is used to determine the frictional pressure loss due to pipeline flow. NRe is defined as NRe=Du[unitless] where D is the diameter of the pipe [m] U is the velocity of the fluid in the pipe [m/s] is the density of the fluid in the pipe [kg/m3] is the viscosity of the fluid in the pipe a) Using dimensional analysis, determine the units of viscosity, in SI base units. b) The inside diameter of a pipe is 2.067". Water is flowing in the pipe at 5ft/s. The viscosity of water at 20C is about 0.9cP. What is the Reynolds number of the flow? You will need to convert several units to do this, and you will need to find some data. Document your sources. c) What is the mass flow rate of water in the pipe
