Please Show work
Assume that the wall shear stress, Tw, created when a fluid flows through a pipe (see Figure a) depends on the pipe diameter, D, the flowrate, Q, the fluid density, p, and the kinematic viscosity, U. Some model tests run in a laboratory using water in a 0.2-ft-diameter pipe yield the vs. Q data shown in Figure b. Perform a dimensional analysis and use model data to predict the wall shear stress in a 0.5-ft-diameter pipe through...

EDIT: The fluid in the system is water. There is no data
regarding the inclination of the pipe. It's known that the
equipment used includes a fluid flow piping system (AFT), hydraulic
bench (FME00), barometer, and psychrometer. Also added an appendix
that has recommended equations.

Reynolds number is a dimensionless number that is used in Fluid Mechanics to distinguish between the laminar and turbulent flows particularly in pipes. Consider a pipe where the flowing fluid has the following properties: ρ is the density of the fluid (SI units: kg/m^3) u is the velocity of the fluid with respect to the object (m/s) D is pipe diameter (m) μ is the dynamic viscosity of the fluid (Pa·s or N·s/m^2 or kg/m·s) m is he mass of...
