**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
