Question

For the impulse turbine blade with four jets producing 100 m/s velocity each, what is the total velocity at the outlet?

a) 400 m/s
b) 200 m/s
c) 800 m/s
d) 100 m/s

Answer 1

The total velocity at the outlet of an impulse turbine blade with four jets producing 100 m/s velocity each is 400 m/s.

Step-by-step explanation:

In an impulse turbine blade with four jets producing a velocity of 100 m/s each, the total velocity at the outlet can be calculated by summing the individual velocities. Since the jets are parallel and in the same direction, we can use vector addition to find the resultant velocity.

Adding the velocities together, we get:

Total velocity = 100 m/s + 100 m/s + 100 m/s + 100 m/s = 400 m/s

Therefore, the total velocity at the outlet is 400 m/s.
