Continuum Hypothesis in Fluid Mechanics The macroscopic behavior of fluids makes them appear to be continuous. However‚ when viewed at the microscopic scale fluids cannot be viewed as continuous. The fluid under consideration will have molecules bombarding each other. It is not possible to declare the fluid velocity at a point as there is no guarantee that the fluid molecules are present at that point at a particular instant of time. When we calculate the fluid velocity or density at a point it

Q.2 (from Street‚ Watters‚ and Vennard) The weight density γ = ρg of water in the ocean may be calculated from the empirical relation γ = γo + K(h1/2)‚ in which h is the depth below the ocean surface‚ K a constant‚ and

Absolute entropy is entropy calculated relative to the absolute reference point determined by the third law of thermodynamics. Absolute humidity (specific humidity or humidity ratio) is the mass of water vapor present in a unit mass of dry air; that is‚ it is the ratio of the mass of water vapor to the mass of dry air in atmospheric air. Absolute pressure is the actual pressure at a given position and it is measured relative to absolute vacuum (i.e.‚ absolute zero pressure). Throughout this

they influence friction losses. Introduction Friction loss is the loss of energy or “head” that occurs in pipe flow due to viscous effects generated by the surface of the pipe. This energy drop is dependent on the wall shear stress (τ) between the fluid and pipe surface. The shear stress of a flow is also dependent on whether the flow is turbulent or laminar. For turbulent flow‚ the pressure drop is dependent on the roughness of the surface‚ while in laminar flow‚ the roughness effects of the wall
