Elementary concepts – properties – concept of gauge and absolute pressure, measurement of pressure using manometers of different types.
Hydrostatic force on plane and curved surface – center of pressure – lock gates – buoyancy and stability of submerged and floating bodies – metacentric height – period of oscillation.
Types of flow, definitions and explanations of unsteady, steady, non-uniform, laminar and turbulent flows. Ideal flow – rotational and irrotational, stream function, potential function. Path line, streak line and stream line – continuity equation – derivation, application of one dimensional steady flow – circulation and vorticity – Basic flow fields such as uniform flow, source, sink, doublet, vortex flow, spiral flow – superposed flows.
