Q1: Apply appropriate solution method using math principles to prove that "the pressure at a point in a fluid has the same magnitude in all directions". Support your answer with sketch. Answer: Px Pz = Pn P are the mean pressures at the three surfaces in the x- and z-directions. Q2: Formulate the issue and identify key variables to prove that [AP = P2 - P, = pg Az = y, Az], where y, and p are the specific weight and density of the fluid, respectively. Az is the vertical distance. Support your answer with sketch. Q3: From fluid mechanics science perspective, define the center of gravity and the center of pressure. Q4: Identify the hydrostatic force acting on the top surface of a submerged rectangular plate by applying principles of engineering for the following cases: 1 tilted plate, (2 vertical plate, and 3 horizontal plate. Support your answer with sketch. Q5: By applying principles of fluid mechanics science, define the "rigid-body" and identify its features. Q6: Formulate the issue…

A mercury manometer is used to measure the pressure (Pgas) of a gas enclosed in a container. On Earth, there is a height difference Ah between the two columns of mercury, as shown in the diagram. Pgas mercury This device is now taken to Jupiter (acceleration of gravity gJup 24.79 m/s2) and used in an enclosure which is kept at the Earth's atmospheric pressure (Po = 101 kPa). What happens to Ah? Ah would increase Ah would not change Not enough information to tell Ah would decrease
