FOR CE-3E ONLY PLEASE DO NOT SHARE Absolute Pressure 1. This is a type of pressure being measured from absolute zero 101.3 kPa 2. it is the type of standard atmospheric pressure in SI unit 14.7 psi 3. it is the type of standard atmospheric pressure in English System Gage Pressure 4. This is a type of pressure that is based on the column of fluid. Eccentricity 5. it is the distance from center of gravity to center of pressure Specific Gravity 6. This is the ratio of the relative density of a substance over the relative density of water. Buoyant Force 7. It is the force that pushes the thing upward in the water. It is equal to the weight of the liquid multiplied by the displacement of the displaced volume. It also acts through the center of gravity or centroid of the displaced volume. R = √FH^2 + Fv^2 8. The formula for the magnitude of the resultant hydrostatic force h-bar (ℏ) 9. is the vertical distance of the centroid from the liquid surface. It starts from the center of gravity to the liquid surface. y-bar" (ȳ) 10. The distance from center of gravity to liquid surface parallel to the inclined surface. Yp or hp 11. It starts from the center of pressure to the liquid surface. ℏ 𝑠𝑖𝑛 θ 12. It is the formula for ȳ. It is also the formula for the new distance of the centroid from the liquid surface along the y-axis. Open Manometer 13. A type of manometer that are used for measuring gage pressure with the use of gage liquid. This type contains an atmospheric level. Differential Manometer 14. A type of manometer that are used for the measurements of pressure difference between two points. It does have any atmospheric level. 𝐹ℎ = γℏ𝐴 15. Formula for horizontal hydrostatic force on submerged plane surface. hp = ℏ + e 16. Formula for the location of the center of pressure. Imaginary Volume 17. This is the type of volume considered if the volume of the liquid is below the curve. Real Volume 18. This is the type of volume is considered if volume of the air is below the curve Buoyancy 19. This is the force that pushes the things upward into water preventing it from sinking. Density 20. This is the mass per unit volume of a substance 𝐹𝑏 = γ𝐿𝑉𝐷 21. Formula for buoyancy. 𝐹𝑏 = γ 𝑉𝑜𝑙 22. Formula for vertical hydrostatic force Neutral Buoyant Force 23. It exist when the buoyancy is equal in the weight when an object will remain at whatever the location it is placed below the fluid surface Pabs = Patm + Pg 24. Formula for Absolute Pressure
