3. FLUID STATICS I. Buoyancy Forces 2. Hydrostatic Force 3. Pressure Measurement F, P.A Fluid deals with the fluid behaviour and its effects when at rest. A fluid is said to be at rest if no shear stresses acting on fluid particle. Eg. no viscosity Only 2 forces involved I. Body Force (self weight of fluid matter) 2. Normal force on the surface due to pressure intensity of the fluid

4. BUOYANCY PRINCIPLE Buoyancy is a phenomena which is observed when a solid body interact with any liquid. There are 3 possibilities: I. The body can float (partially submerged) 2. The body can sink or (submerged fully) 3. Body top surface coincide with liquid surface -
