Question

Recall that the Reynolds number is a dimensionless number that we use to discuss the flow charecteristics of moving fluids. Generally speaking it is the ratio of momentum forces to viscous forces, and it depends on the diameter of the pipe, the density of the fluid, the velocity of the moving fluid, and the viscosity of the moving fluid. It is normally given by Re Where Re - Reynolds number [dimensionless) p- fuid density v- fud velocity D- pipe diameter -fluid viscosity 6、 ㅣ set up an experiment in which I can change the velocity of the fluid without changing any of the other variables. I then establish the following equation: Re 254 * 1' What are the units on the constant 254? a. b. Fluid velocity is rarely, if ever, measured in units of centimeters per second; realistic fluid flow rates would be very large numbers when expressed in centimeters per second. More realistic measurement units would be feet per Page 1 of 2 second. Convert this equation such that it will accept fluid velocity measured in feet per second and calculate a dimensionless Reynolds number c. I know that in my experiment that the pipe diameter is one inch and the viscosity is 1 centipoise. What is the specific gravity of the fluid in my experiment?
