Civil 2-1 Fluid Mechanics Important Topics Questions
UNIT I
Introduction: Dimensions and units – Physical properties of fluids - specific gravity, viscosity,
surface tension, vapour pressure and their influences on fluid motion, pressure at a point, Pascal’s
law, Hydrostatic law -atmospheric, gauge and vacuum pressures- measurement of pressure. Pressure
gauges, Manometers: Differential and Micro Manometers.
Hydrostatics: Hydrostatic forces on submerged plane, Horizontal, Vertical, inclined and curved
surfaces – Center of pressure.
UNIT – II
Fluid Kinematics: Description of fluid flow, Stream line, path line and streak line and stream tube.
Classification of flows: Steady, unsteady, uniform, non-uniform, laminar, turbulent, rotational and
irrotational flows – Equation of continuity for one, two , three dimensional flows – stream and
velocity potential functions, flow net analysis.
Fluid Dynamics: Surface and body forces – Euler’s and Bernoulli’s equations for flow along a
stream line - Momentum equation and its application – forces on pipe bend.
UNIT – III
Laminar Flow and Turbulent Flows: Reynold’s experiment – Characteristics of Laminar &
Turbulent flows, Shear and velocity distributions, Laws of Fluid friction, Hagen-Poiseulle Formula,
