The pressure rise, Δp, across a pump can be expressed as:Δp=f(D, p,ω,Q)where D is the impeller diameter, p the fluid density, ω the rotational speed, and Q the flowrate. Determine a suitable set of dimensionless parameters.

An ideal polarizer with its transmission axis rotated 30 degrees to the vertical is placed in a beam of unpolarized light of intensity 10w/m^2. after passing through the polarizer, what is the intensity of the beam? a. 8.7 w/m^2 b. 7.5 w/m^2 c. 5.0 w/m^2 d. 10 w/m^2 e. 2.5 w/m^2

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
