Question:

A tank of water (15°C) with a total weight of 200 N (water plus the container) is suspended by a vertical cable. Pressurized air drives a water jet (d = 12 mm) out the bottom of the tank such that the tension in the vertical cable is 10 N. If H = 425 mm, fi nd the required air pressure in units of atmospheres (gage). Assume the flow of water is irrotational.
