The pressure coefficient is defined by the ratio between the static pressure difference and the dynamic pressure (pictured):
Where P is the static pressure [Pa], P∞ is the reference static pressure [Pa], ρ is the density [kg/m3], and V is the velocity [m/s]. Using the primary dimensions and their units, show that the pressure coefficient is dimensionless.
The thrust F of a propeller is generally thought to be afunction of its diameter D and angular velocity V , the forwardspeed V , and the density ρ and viscosity μ of the fl uid.Rewrite this relationship as a dimensionless function.
The thrust force, F generated by a propeller is found to depend on the followingparameters: diameter D, forward velocity u, density ρ, viscosity µ and rotationalspeed N. Determine the dimensionless parameters to correlate the phenomenon
