The airflow system in Prob. 7.60 is measured with a venturi having like dimensions as the orifice, i.e., the same pipe diameter and throat diameter. Calculate the flow rate in kg/s for the same pressure and temperature measurements as in Prob. 7.60.

Prob. 7.60

An orifice is installed according to ASME specifications in a 5.0-cm-diameter pipe. The diameter of the orifice is 2.5 cm and the pressure taps are one diameter upstream and one-half diameter down-stream. Amano meter is used to measure the orifice pressure differential as 1932 mmH2O and the upstream pressure is measured as 400 kPa gage pressure with the local barometer reading as 750 mmHg. The fluid is air at a temperature of 27?C. Calculate the airflow rate in kg/s.
