A pipe at ground level supplies a building with water moving at 2.7 m/s. The pipe then rises 80 meters to the top of the building and reduces in diameter such that the water flows at 9.0 with a pressure of 159000. Find the necessary pressure at the bottom to push the water up to the top.

A 10 meter long lever is used to move a large rock. You push down on one end of the lever and the rock pushes down on the other end. and there is a pivot point on the ground that pushes up on the lever 0.6 meters from the rock. Find how much force it would take to move a rock with a mass of 213 kg.
