Air flows thru a device shown in the figure below. If the flow rate is large enough, the pressure within the constriction will be low enough to draw the water up into the tube. The specific weights of water and air are 9.80 and 12 KN/m3, respectively. If frictional loss is neglected, compute the following: a) the pressure of air at point 2 (kPa), b) the flow rate (L/s), and c) the pressure needed at section 1 to draw the water into section 2 (kPa). Note: Maintain up to 3
