Repeat Prob. 8–123 for a Venturi neck diameter of 6 cm.
Data from Problem 8–123
The mass flow rate of air at 20°C (ρ = 1.204 kg/m3) through a 18-cm-diameter duct is measured with a Venturi meter equipped with a water manometer. The Venturi neck has a diameter of 5 cm, and the manometer has a maximum differential height of 40 cm. Taking the discharge coefficient to be 0.98, determine the maximum mass flow rate of air this Venturi meter/manometer can measure.
