A fluid machine is a device which converts the energy stored by a fluid into mechanical energy or vice versa . The energy stored by a fluid mass appears in the form of potential, kinetic and intermolecular energy. The mechanical energy, on the other hand, is usually transmitted by a rotating shaft. Machines using liquid (mainly water, for almost all practical purposes) are termed as hydraulic machines. In this chapter we shall discuss, in general, the basic fluid mechanical principle governing the energy transfer in a fluid machine and also a brief description of different kinds of hydraulic machines along with their performances.
Name of Practicals
To determine the coefficient of discharge of an orifice of a given
shape. Also to determine the coefficient of velocity and orific mouth piece.
Orific meter, Venturimeter
To calibrate an orifice meter, venturimeter, and bend meter and study the variation of the co-efficient of discharge with the Reynolds number.
To study the transition from laminar to turbulent flow and to determine the lower critical Reynolds number.
laminar & turbulent flow apperatus
To study the variation of friction factor, „f‟ for turbulent flow in commercial pipes.
Friction Factor Equipment
To study the boundary layer velocity profile over a flat plate and to determine the boundary layer thickness
