A large tank of water has a hose connected to it. The tank is sealed at the top and has compressed air between the water surface and the top. When the water height h has the value 3.5 m , the absolute pressure p of the compressed air is 4.20 * 10^5 Pa. Assume that the air above the water expands at cosntant temperature, and take the atmospheric pressure to be 1.0 * 10^5 Pa. a) What is the speed with which water flows out of the hose when h = 3.50 m? b) and c) just give other values to plugs in for the height. Now the question I have is: Can't i just use Bernouilli's equation? On the first one i did and got the right answer, but on part b and c i didn't, so what is the problem?
