SHOTS - FLUID MECHANICS

💥 Pascal second is the unit of dynamic viscosity. 

💥 An ideal fluid is frictionless and incompressible. 

💥 Cm^2/sec is the unit of kinematic viscosity. 

💥 NS/m^2 is the unit of dynamic viscosity. 

💥 Kinematic viscosity=(dynamic viscosity/mass density). 

💥 Surface tension of water increases with decrease in temperature. 

💥 Centre of buoyancy is always coincide with the centroid of the volume of fluid displaced. 

💥 A floating body is said to be in a state of stable equilibrium when the meta centric height is above the centre of gravity. 

💥 Stream lines and path lines always coincide in case of steady flow. 

💥 Equation of continuity is based on principle of conservation of mass. 

💥 The pitot tube is used to measure stagnation pressure. 

💥 Venturi meter is used to measure the discharge. 

💥 The major loss of energy in long pipes is due to friction. 

💥 The losses are more in turbulent flow. 

💥 Trapezoidal shape is the best hydraulic section. 

💥 The height of the hydraulic jump is equal to the difference in conjugate depth. 

💥 Rayleigh lines are based on momentum and continuity.
