the figure shows a reservoir of water connected to a hydraulic press chamber, which is elevated relative to the reservoir. when the water flows down from the press chamber to the reservoir it does so at a gradually decreasing rate.
the solution says this decreasing rate is due to a gradual decrease in the pressure difference between the two chambers. it says the water in the press chamber (elevated) is under higher pressure, and that as more water flows down to the reservoir, the flow rate decreases because the pressure difference is getting smaller.
i thought bernoulli's says that more elevated sections of a pipe containing fluid have lower water pressure.. not higher? do i have this backwards..
thanks
