FLUID MECHANICS & HYDRAULIC MACHINERY

Fluid Mechanics Syllabus as per JNTUH. However we cover other universities syllabus as well effectively to ensure student’s  high success rate in exams and help them to get good scores.

UNIT – I

Introduction: Dimensions and units – Physical properties of fluids specific gravity, viscosity, surface tension, vapor pressure and their influences on fluid motion pressure at a point, Pascal’s law, Hydrostatic law – atmospheric, gauge and vacuum pressure- measurement of pressure. Pressure gauges, Manometers: differential and Micro Manometers. Hydrostatic forces on submerged plane, Horizontal, Vertical, inclined and curved surfaces – Center of pressure. Derivations and problems.

UNTI – II

Buoyancy and floatation: stability of bodies, meta centre, liquids in relative equilibrium.
