Figure shows an example of a hydraulic accumulator, which is a device for reducing pressure fluctuations in a hydraulic line or pipe. The fluid density is ?, the plate mass is negligible, and the plate area is ?. All the given pressures are gauge pressures. Write down the equations of motio

See the sketch below from our textbook (not to scale!), where the liquid in the open-top tank and pipe is water, and the manometer is partially filled with mercury (from "B" around to "C"). You should know the density of water, and assume mercury has density 13.5x that of water. What is the pressure at "A" if h = 200 mm? AQ B E 400 mm C150 mm 100 mm 200 mm Mercury

Can someone please explain the parts marked on the photo. Like why is there no two included in the other equation and the steps taken to find Poisson equation. Please actually show step by step including the calculations to find the final answer. Thanks

Q4: A 7-cm diameter solid aluminum ball (SG = 2.7) and a solid brass ball (SG-8.5) balance nicely when submerged in a fluid as shown in figure. a) If the fluid is water, what is the diameter of the brass ball? b) If the brass ball has a diameter of 3.8 cm, what is the density of the fluid? 2 pulleys Fluid brass aluminum D= 7 cm +
