CE6403 Important Questions APPLIED HYDRAULIC ENGINEERING Regulation 2013
Sample CE6403 Important questions for Applied Hydraulic Engineering:
1. What is meant by wetted perimeter?
The wetted perimeter (p) is the length of the line of intersection of the channel wetted surface with the cross section plan normal to the direction of flow.
2. Define critical depth:
It is defined as the depth of flow of water at which the specific energy is minimum.
3. Define cavitations
Cavitations is defined as phenomenon of formation of vapour bubbles in a region of a flowing liquid where the pressure in the liquid is falls below than vapour pressure and sudden collapsing of these vapour bubbles in a region of higher pressure.
4. What is known by governing of a turbine?
Governing of a turbine is defined as the operation by which the speed of the turbine is kept constant under all conditions of working . It is done by oilpressure generator.
5. Define Hydraulic Efficiency:
It is defined as the ratio of power delivered to the runner to the power supplied at the inlet.
6. Define mechanical efficiency
It is defined as the ratio of power at the shaft of the turbine to the power delivered by the water to runner
7. Explian tangential flow turbine
If the water flows along the tangent of the runner, the turbine is known as the tangential flow turbine.
8. Expain radial flow turbine
If the water flows in the radial direction through the runner the turbine I called radial flow turbine.
9. what is radial discharge?
This means the angle made by absolute velocity with the tangent on the wheel is 90 and the component of whirl velocity is zero.
10. Define Francis turbine:
Inward flow reaction turbine having radial discharge at outlet is known as francis turbine
