PLEASE HELP


A container of water has a cross-sectional area of Ac = 0.25m2. A piston with mass mp = 18kg, sits on top of the water as shown in Figure 1. The height of the water which the piston is sitting on is h1 = 0.45m.
There is a spout located h2 = 0.17m from the bottom of the tank, open to the atmosphere, and a stream of water exits the spout. The cross sectional area of the spout is As = 8.5 × 10−3m2. A valve on the spout
is closed. How much force is the water in the spout exerting on the valve?
