Sample CE8403 Important Questions Applied Hydraulic Engineering

31.Explain outward flow radial turbine
If the water flows radially from inwards to outwards the turbine is known sa outward
radial flow turbine.
32.Define axial flow turbine
If the water flows through the runner along the direction parallel to the axis of rotation CE8403 Important Questions Applied Hydraulic Engineering
of the runner the turbine is called axial flow turbine.
33.what is Pelton wheel:
Pelton wheel or Pelton turbine is a tangential flow impulse turbine. The water strikes the
bucket along the tangent of the runner . The energy available at the inlet of the Turbine is only
kinetic energy.This turbine is used for high heads.
34.What is breaking jet? CE8403 Important Questions Applied Hydraulic Engineering
When the nozzle is completely closed ,the amount of water striking the runner reduces to
zero but the runner due to inertia goes on revolving
for a long time to stop the runner in a short time a small nozzle is
provided which direct the jet of water on the back of vanes .This jet of water is called
breaking jet.
35.What is jet ratio?
It is the ratio of pitch diameter (D) to the diameter of jet (d).
36.What is Draft tube? CE8403 Important Questions Applied Hydraulic Engineering
A tube or pipe of gradually increasing area is used for discharging water from the exit
of the tubine to the tail race is called draft tube.
37.Define Degree of Reaction (R)
It is defined as the ratio of change of pressure energy inside the runner to the change
of total energy out side the runner. CE8403 Important Questions Applied Hydraulic Engineering
38.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.
39.Define Francis turbine:
Inward flow reaction turbine having radial discharge at outlet is known as francis turbine CE8403 Important Questions Applied Hydraulic Engineering
