2. Consider a large industrial fan where the input power, W, depends on the fan impeller diameter, D, fluidviscosity, u, fluid density, p, volumetric flow rate, Q, and blade rotational rate, w.a) What are the appropriate dimensionless groups (Pi terms) if we consider D, p, and Q as repeating (reference)variables.b) If a model fan has a diameter, Dm, that is half of the prototype fan diameter, D, , what should be the ratio ofthe model blade rotation rate, Wm , to prototype, wp, to have dynamic similitude. Assume the same fluid (air)properties; that is viscosity and density are the same in both cases.

Fluid Mechanics Problem Note: Fluids are assumed to be at 20oC.
Q2:A) An experimental text program is being set up to calibrate a new flow meter. The flow meter is to measure the mass flow rate of liquid flowing through a pipe. It is assume the mass flow rate (m) is a function of the pressure difference (AP)across the meter, diameter of the pipe (D), viscosity of the fluid (4), and the density of the fluid (p). Using the dimensionless analysis, find the-groups for this case study.
5. Consider a Pitot probe in high-speed flow.(c) You are flying through air at static p∞ = 0.8 atm [abs]. Your velocimeter broke,but you are still receiving the following direct stagnation pressure readings (atm[abs]) from the Pitot probe mounted on your aircraft’s noise: i) 3.152 ii) 1.357 iii) 38.428 iv) 0.8 Find the freestream Mach number corresponding to each of the pressure readings. (d) If we are to believe reading (iv), can we step out of the aircraft safely? Why?
