Question

3. In the manometer shown, which of the points A and B is at a higher pressure, and by how much (psi)? Ou(s0.92) 24㎞ Oil 092) 12 in Mercury (sg-13.6) 4. (a) A vertical triangular surface of height h and base b is submerged in a liquid such that its apex coincides with the liquid surface. Draw this scenario, and indicate the pressure distribution, resultant hydrostatic force F, centroid C, center of pressure P, and distances hc, and hp. (b) Derive an expression for hp (i.e. distance from the liquid surface to the center of pressure of this triangle of height h) such that the relationship can be reduced to the form hp kh) where 0< k<0.95. State the value of k. [Please do not use pressure prism]
