Mechanical Engineering :: Hydraulics and Fluid Mechanics
- A hydraulic intensifier normally consists of
- Center of pressure compared to e.g. is
- In order that flow takes place between two points in a pipeline, the differential pressure between these points must be more than
- The total energy line lies over the centre line of the pipe by an amount equal to
- The specific speed of a turbine is given by the equation
- An open tank containing liquid is made to move from rest with a uniform acceleration. The angle 0 which the free surface of liquid makes with the horizontal is such that (where a = Horizontal acceleration of the tank, and g = Acceleration due to gravity)
- The resultant upward pressure of a fluid on a floating body is equal to the weight of the fluid displaced by the body. This definition is according to
- The discharge through a channel of trapezoidal section is maximum when
- Coefficient of contraction is the ratio of
