Extracted text: Take the specific weight of air = 12 N/m², the specific weight of water = 9800 N/m³, standard gravity = 9.8 m/s², density of water = 1,000 kg/m³. C1. Air flows through a Venturi channel of “circular" cross-section as shown in Figure C1. The diameter at both inlet and outlet is 0.06 m. Compressibility and viscous effects are negligible. Determine the following. (a) The flowrate when water is drawn up 0.20 m in a small tube attached to the static pressure tap at the throat where the channel height is 0.03 m. (b) The channel height, h3, at section (3) where, for the same flowrate as in part (a), the water is drawn up 0.10 m. (c) The pressure needed at section (1) to produce this flow.
