U1 , A1 U2 , A2 Figure 5.40: Venturi meter. Since the volume-flow rate in a Venturi meter is Q = A2 the pressure difference divided by is p1 - p2 1 A2 = 1- 2 2 A2 1 Q A2 2 2 (p1 - p2 ) (1 - A2 /A2 ) 2 1 Thus, for the given values of Q, A1 and A2 , we arrive at p1 - p2 1 25 ft2 = 1- 2 36 ft2 50 ft3 /sec 5 ft2 2 = 15.28 ft2 sec2 Hence, for air, water and mercury, we have the following. Fluid (slug/ft3 ) p1 - p2 (lb/ft2 ) Air 0.00234 0.036 Water 1.94 29.6 Mercury 26.30 402 ...
