By referring to Figure 1, explain why the atmospheric pressure, Patm can be subtracted when analyzing hydrostatic forces on submerged surfaces. Patm h IK = h DII

How can you calculate the hydrostatic force FR (magnitude) and its point of application (center of pressure) acting on the top surface of a submerged rectangular plate for vertical, and horizontal case.Explain

Round off at the final answer only! As illustrated, the semicircular gate AB is utilized to store kerosene. In meters, how far is the center of pressure from A? Kerosene SG= 0.82 5 m 3 m A B -P Gate: Side view

1. Find the density of an oil filled in the liquid column as shown in figure. Given that absolute pressure at the bottom is 700 kPa, atmosphere pressure is 1.0132 bar. where X-4m; Y = 4m, Z=1.25m. water oil Mercury The density of the oil = (unit in kg/m³) =

There are various methods that can be used to calculate the hydrostatic force on a submerged surface. Which of the following statements are correct? (i) (iii) The pressure prism method gives good understanding of the fundamentals but it can only be used for plane surface uniform in the spanwise direction. The parallel axis theorem can be used for surface not uniform in the spanwise direction such as a circular or triangular plane surfaces, but it is limited to simple geometry where the second moment of area can be easily defined. The elementary area method can be used for any 2 or 3 dimensional surface as long as the geometric unit normal vector is known at any point on the surface. (A) (B) (C) (D) (i) and (ii) (i) and (iii) (ii) and (iii) All of the above The Eulerian frame of reference is commonly used in analyzing fluid problems instead of the Lagrangian frame of reference. The main differences between these 2 frames of reference are: (i) The steady motion in Lagrangian frame of…

Plese use physics to answer
