Write short note on the following Ogee spillways

Answer»

This is the most common TYPE of spillway provided on GRAVITY dams. The profile of the spillway is OGEE or ‘s’ shaped.The overflowing water is guided smoothly over the crest and profile of the spillway so that the overflow water does not break contact with the spillway surface.If this is not assured, a vacuum may form at a point of separation and CAVITATION may occur. In addition to cavitation, vibration from the alternate making and breaking of contact between the water and face of DAM may result in serious structural damage.

In newton’s rings experiment, if we reduce the radius of curvature of planoconvex lens to zero, what will be effect on newton’s rings?

Answer»

In Newton’s ring EXPERIMENT, a plano-concave air film is formed between the glass slide and the convex lens. The formation of concentric circular fringes can be SEEN by interference. Irrespective of the nature of the lens ( whether plano or biconvex) for the same of RADIUS of curvature, there will be no difference in the nature of the fringes. There MAY be a slight variation only in the intensity.

Please solve the question?

Answer»

NON CONTACT FORCES -the OBJECT which reacts to the force without any physical contact , the occurence of this force cannot be visualized.

CONTACT FORCES - the object reacts to this force with some physical contact , the occurence of this force can be visualized.

contact forces

Applied Force.

GRAVITATIONAL Force.

Discuss ogee spillway

Answer»

This is the most common type of spillway PROVIDED on gravity dams. The profile of the spillway is ogee or ‘s’ shaped.The overflowing water is guided smoothly over the crest and profile of the spillway so that the overflow water does not break contact with the spillway surface.If this is not assured, a vacuum may form at a point of separation and cavitation may occur. In addition to cavitation, vibration from the alternate making and breaking of contact between the water and face of dam may result in serious structural damage.Hence the upper profile of the ogee is, made to confirm with the lower nappe of a freely FALLING jet of water over a SHARP crested weir, when the flow rate corresponding to the MAXIMUM DESIGNED capacity of the spillway.Here, the essential difference between the straight drop spillway and the ogee or overflow spillway should be clearly noted. In the straight drop spillway type, the jet falls clearly away from the face of the spillway and the gap between the jet and face is kept ventilated.In the ogee or overflow spillway, the falling water is made to glide over the curved profile of the spillway.A smooth gradual reverse curvature on the downstream face of the spillway is provided. This reverse curve turns the flow on the apron of a stilling basin or into the spillway discharge channel.
