please explain step by step

Question 1. (15 pts) If the flow rate is large enough, the pressure within the constriction will be low enough to draw the water up into the tube. (a) (10 pts) Determine the flow rate and the pressure needed at section (1) to draw the water into section (2). Neglect compressibility and viscous effects. Take air density =1.12kg/m3. (b) (5 pts) Determine the magnitude and the direction of the force needed to be applied on the tube from the section (1) to the exit
