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 x 10-3m2. A valve on the spout is closed. How much force is the water in the spout exerting on the valve

On another planet that you are exploring, a large tank is open to the atmosphere and contains ethanol. A horizontal pipe of cross-sectional area 7.0×10−4m27.0×10−4m2 has one end inserted into the tank just above the bottom of the tank. The other end of the pipe is open to the atmosphere. The viscosity of the ethanol can be neglected. You measure the volume flow rate of the ethanol from the tank as a function of the depth hh of the ethanol in the tank. If you graph the volume flow rate squared as a function of hh, your data lie close to a straight line that has slope 2.09×10−5m5/s22.09×10−5m5/s2. What is the value of gg, the acceleration of a free-falling object at the surface of the planet? Express your answer with the appropriate units.

A moonshiner produces ethanol and stores it in a stainless tank in the form of a cylinder, 20 cm in diameter with a tight-fitting piston at the top. The total volumetric capacity of the tank is 0.20 m3 (200L). In an attempt to squeeze a little more into the tank. he piles lead bricks on the piston, the total mass of the bricks and piston is 120 kg. What additional volume of ethanol can he squeeze into the tank? Kethanol=11 x 10-10 Pa-1.
