Question details

Dimensional analysis It is postulated that the pressure surplus (relative to free-stream) around a cross-flow cylinder is a function of the air density, air viscosity, air speed, cylinder diameter D, and the location on the cylinder surface measured from the stagnation point θ: Treating the pressure surplus as a single variable, this relationship can be reduced to a relationship between four II groups: 11,-s(112, 113, 114) Find all the relevant Π groups. (Hints: Make pair, U , and D the repeating variables, and remember to treat (P - Po) as a single variable. True | False With the hoses from the Pitot-static tube connected to the top of the manometer bank, the pressure surplus P(x)- Po at any location on the airfoil can be found by using where hc) is the manometer fluid height at location and h24 is the manometer fluid height associated with the static reading of the Pitot-static tube. In the equation above, ρ is the density of the manometer fluid | air
