Flоw in а pipe is meаsured using аn оrifice plate, as shоwn in the figure. The volumetric flow rate QQ depends on the pressure drop across the plate ΔpDelta p, fluid density ρrho, pipe diameter DD, and orifice diameter dd. Task: Using dimensional analysis, express this relationship in dimensionless form. Select the correct answer: A. ρQD2=f (dD)displaystyle frac{rho Q}{D^2} = f!left(frac{d}{D}right) B. ρQD2Δp=f (dD)displaystyle frac{rho Q}{D^2 Delta p} = f!left(frac{d}{D}right) C. ρQΔp=f (dD)displaystyle frac{rho Q}{sqrt{Delta p}} = f!left(frac{d}{D}right) D. ρ QD2Δp=f (dD)displaystyle frac{sqrt{rho},Q}{D^2 sqrt{Delta p}} = f!left(frac{d}{D}right)
