Derive an expression for the shear stress \tau at the pipe wall when an incompressible fluid flows through a pipe. Use dimensional analysis \pi theorem with the following significant parameters: pipe diameter D, flow velocity V, and dynamic viscosity \mu and density \rho of the fluid. (Choose \rho, V, D as basic physical properties).

It is typically measured in units such as pascals (Pa) or pounds per square inch (psi). - V represents volume, which is the amount of space occupied by the fluid. It is typically measured in units such as cubic meters (m^3) or liters (L). - D represents density, Show more…

Choose a substance and give several of its physical properties and several of its chemical properties.
What makes physical properties different from chemical properties? Choose the correct answer O A) Physical properties relate to elements rather than compounds B) Physical properties appear only after a chemical change occurs. C) Physical properties describe elements in the solid state rather than in the liquid or gas state D) Physical properties can be observed without attempting to change the identity of the substance
