In the next figure, water is flowing in pipe A and oil (S.G. = 0.82) is flowing in pipe B. If mercury is used as manometer liquid (S.G. = 13.6) determine the pressure difference between A and B in psi Abdelal
Determining the hydrostatic force resulting from the hydrostatic pressure is critical for many engineering projects, such as dams and water towers. Resultant force on any submerged plane can be represented as 𝐹 = 𝛾 ℎ𝐴 Where: 𝛾 = Specific weight of the fluid 𝐴 = Area of the submerged plane = Vertical distance of centroid Abdelal

Location of the resultant force is: 𝑦 𝑐? = 𝑦 + 𝐼 ? 𝑦𝐴 Where: 𝑦 𝑐? =Inclined distance to the center of pressure (location of resultant force) 𝑦 = Inclined distance to centroid from x-axis 𝐼 ? = moment of inertia with respect to own centroid. A = is the surface area. Notice that the center of pressure of any submerged surface is always below the centroid of the surface area. Review derivation of the formula above in your Fluid mechanics book !! e Abdelal

A round viewing window of diameter D = 0.8m is situated in a large tank of seawater (S=1.03). The top of the window is 1.2m below the water surface, and the window is angled at 60 o with respect to the horizontal. Find the hydrostatic force acting on the window and locate the corresponding CP Abdelal

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
