Air (p = 1.2 kg/m3) flows through an orifice plate set in a pipe of 400 mm diameter. A water manometer (p %3D = 1000 kg/m3) is used to indicate the pressure differential across the orifice and can read a maximum level difference of 450 mm. The maximum air flow rate in the pipe is expected to be 4.6 m/s. Assume that Cd = 0.63. i. Select a suitable orifice plate to measure the flow (i.e., d). ii. What will be the reading if the flow rate is 10% of the maximum?
