67. (a) The continuity equation yields Av= aV, and Bernoulli’s equation yields 2211pvVρρΔ+=, where Δp= p1– p2. The first equation gives V= (A/a)v. We use this to substitute for Vin the second equation, and obtain ()2pvAav=. We solve for v. The result is22.(/) 1papvAaA aΔΔ==−−(b) We substitute values to obtain
