1 LECTURE NOTES ON FLUID MECHANICS (ACE005) IV semester (Autonomous) (2018-19) Dr. G. Venkata Ramana Professor. DEPARTMENT OF CIVIL ENGINEERING INSTITUTE OF AERONAUTICAL ENGINEERING (Autonomous) DUNDIGAL, HYDERABAD-500043 2 FLUID MECHANICS IV Semester: CE Course Code Category Hours / Week Credits Maximum Marks ACE005 Core L T P C CIA SEE Total 3 1 - 4 30 70 100 Contact Classes:45 Tutorial Classes:15 Practical Classes: Nil Total Classes: 60 OBJECTIVES: The course should enable the students to: I. Understand and study the effect of fluid properties on a flow system. II. Apply the concept of fluid pressure, its measurements and applications. III. Explore the static, kinematic and dynamic behavior of fluids. IV. Assess the fluid flow and flow parameters using measuring devices. UNIT-I PROPERTIES OF FLUIDS AND FLUID STATICS Classes: 09 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 pressures.

action of constant shear force is illustrated. We explain in detail here deformation behaviour of a solid and a fluid under the action of a shear force. In Fig.L1.1, a shear force F is applied to the upper plate to which the solid has been bonded, a shear stress resulted by the force equals to , where A is the contact area of the upper plate.
