This document discusses fluid statics and fluid pressure. It begins by introducing the concept that fluids only experience compressive stresses and transmit pressure perpendicular to boundaries. It then defines absolute and gauge scales for measuring pressure and discusses how pressure at a point in a fluid is equal in all directions. Pascal's principle is introduced, stating that pressure is transmitted undiminished throughout a fluid. Variations in pressure with height in both compressible and incompressible fluids are analyzed based on hydrostatic equations. Pascal's paradox is briefly discussed at the end.
