A5 gallon, cylindrical open container with a bottom area of 120 in? is filled with glycerin (SG=1.26) and rests on the floor of an elevator. Notes: The density of water is 62.4 lbm / t. Useful conversion: 1 gal = 231 in3. The weight of the container is negligible. (a) What resultant force does the container exert of the floor of the elevator when the elevator is stopped. F= Ibf (b) Determine the fluid pressure at the bottom of the container when the elevator has an upward acceleration of 3.0 ft/s?. Pb = | Ibf / ft? (c) What is the resultant force when the elevator accelerates upwards at 3.0 ft/s?. F = |Ibf

1. Hydrostatic Force on Plane Surface. An open rectangular tank is 7 m high and has a square base 5 m on a side. If the tank is half-filled with fresh water (density is 1000 kg/m'), determine (a) the total hydrostatic force on a vertical side, in kN and (b) the location of the center of pressure as measured from the liquid surface, in cm. Draw the side view of tank showing the hydrostatic force F and the distance, yp. Is I + Ad a. Magnitude: F = yh,A b.Direction: Perpendicular to the Area c. Location: y, === S.

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…

Use this fact: The weight-density of water is 9800 newtons per cubic meter or 62.5 pounds per cubic foot.

I need help finding the force on a flat door at the bottom of the vessel that has a cross-sectional area of 0.5 m2.

The bottom of a steel "boat" is a 7 m ✕ 8 m ✕ 4 cm piece of steel (ρsteel = 7900 kg/m3). The sides are made of 0.480 cm thick steel. What minimum height must the sides have for this boat to float in perfectly calm water? The side height should not include the thickness of the bottom. (Answer in cm, thanks)

1. Bellow Fig illustrates a cylinder having diameter of 1.8 m and height 1.2 m. The mass of the cylinder is 1019.3 kg which is floating vertically in salty water of density 1025 kg/m³. If an object weighing 2 kN is placed on the top of the cylinder, calculate the maximum height of centre of gravity (z) for the object to keep the cylinder in a state of stable equilibrium. Z 2 kN 0.45m . G₁ G 1.8m 1.2m p=10;
