The mass flow rate of air at 20°C (p= 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. Answer: 0.188 kg/s 18 cm h 5 cm Water manometer
