Question: Carbon dioxide flows through an 8-cm-inside diameter pipe. To determine the mass flow rate, a venturi meter with a throat diameter of 5 cm is installed in the pipe. The pressure and temperature just upstream of the venturi meter are 600 kPa and 40°C, respectively. The difference between the pressure just upstream of the venturi meter and the pressure at the throat of the venturi meter is 15 kPa. Find the mass flow rate of carbon dioxide.
