Governing of a Turbine: Oil Pressure Governor, Needle Valve and Surge Tank! Meaning of Governing of a Turbine: Governing of a turbine means regulating the speed of the turbine. This is accomplished by the use of a turbine governor. A governor is the means to maintain the turbine at a constant design speed even though the load on the turbine [...]
In this article we will discuss about:- 1. Performance of a Turbine under Unit Head 2. Specific Speed of Turbine as a Type Number 3. Model Testing 4. Characteristic Curves. Performance of a Turbine under Unit Head: In the studies of comparison of the performances of turbines of different output, and speeds and different heads, it is convenient to determine [...]
Measurements of Water Level: Methods, Velocity ,Discharge and Instruments . In this article we will discuss about the various devices and instruments used in the measurements of water levels, velocity and discharge. Water Level Measurements: The gauges used for water level measurements may be classified into: (i) Non-self-registering gauges, and (ii) Self-registering gauges. The non-self-registering gauges need an observer to [...]
When a body is placed in a moving fluid, a force is exerted on the body by the moving fluid. Similarly when a body moves within a fluid at rest then also a force is exerted on the body by the fluid. Motion of submarines, torpedos and aeroplanes are examples of this kind. Consider a body placed in a fluid [...]
