Limiting discharge rates for Venturi meters.

(a) Starting with Eq. 15.5-34 (for adiabatic flow), show that as the throat pressure in a Venturi meter is reduced, the mass rate of flow reaches a maximum when the ratio r = P₂/P₁ of throat pressure to entrance pressure is defined by the expression?

(b) Show that for S₁ >> S₀ the mass flow rate under these limiting conditions is?

(d) Obtain results analogous to Eqs. 15B.5-1 and 2 for isothermal flow
