Jet of water having velocity of 18 metre per second strikes a curve in...
Deflection of Jet of Water
Given:
- Velocity of jet = 18 m/s
- Velocity of curve = 10 m/s
- Deflection angle = 120 degrees
Analysis:
When a jet of water strikes a curve, it gets deflected due to the change in direction of the curve. In this case, the jet is moving with a velocity of 18 m/s and strikes a curve moving with a velocity of 10 m/s. The deflection angle is given as 120 degrees. We need to find the angles of the jet at the start and end to avoid shock.
Solution:
When a jet of water strikes a curve, it undergoes a change in direction and velocity. The angle of deflection can be calculated using the following formula:
Angle of deflection = sin-1(V2/V1)
where V1 is the velocity of the jet and V2 is the velocity of the curve.
Substituting the given values, we get:
Angle of deflection = sin-1(10/18) = 36.87 degrees
Therefore, the angle of deflection is 36.87 degrees.
To avoid shock, the jet should be angled at the start and end to match the angle of deflection. This can be done by using a gradual curve or a diffuser to slow down the velocity of the jet.
Conclusion:
The jet of water having a velocity of 18 m/s and striking a curve moving at a velocity of 10 m/s will be deflected through an angle of 36.87 degrees. To avoid shock, the jet should be angled at the start and end to match the angle of deflection.
