67. (a) The continuity equation yields Av = aV , and Bernoulli’s equation yields 22 11 p vV ρρ Δ+ = , where Δ p = p 1 p 2 . The first equation gives V = ( A / a ) v . We use this to substitute for V in the second equation, and obtain () 2 p vA a v = . We solve for v . The result is 2 2 . (/) 1 p ap v Aa A a ΔΔ == −− (b) We substitute values to obtain
