Question

In reaction turbine work is done_______________.
1 point
a. totally due to change in kinetic energy of jet
b. totally due to change in pressure head
c. mostly due to change in pressure head and small amount of work is due to change in kinetic energy
d. mostly due to change in kinetic energy and small amount of work is due to change in pressure head​

Answer 1

Answer:

c) is the correct option

Answer 2

In reaction turbine work is done mostly due to change in pressure head and small amount of work is due to change in kinetic energy.

Small amount of work:

• According to newton's third law of motion the operation of reaction turbines is described.
• Before leaving the wheel head and eventually reduces to atmospheric pressure changes to the velocity.
• Impulse turbines change the direction of flow of a high velocity fluid or gas jet.
