ENB205 Lecture Notes - Lecture 4: Gate Valve, Parallel Axis Theorem, Statics
Document Summary
Fluid statics deals with problems associated with fluids at rest, fluids can be either liquid or gaseous: No relative motion between adjacent fluids layers, no shear stresses in the fluid deforming it. The only stress of concern is the normal stress, which is the pressure the variation of which only due to the weight of the fluid. Hence, gravity is the major factor in fluid statics. Used to determine the forces on floating or submerged bodies and the forces developed by devices like hydraulic presses and car jacks. Also the design of water dams and liquid storage tanks. The complete description of the resultant hydrostatic force acting on a submerged surface requires the determination of: the magnitude, the direction, the line of action of the force. A plate is subjected to fluid pressure distributed over its surface when exposed to a liquid. The wall of a liquid storage tank. The hull of a ship at rest.
