1. A wide channel carries a specific discharge of 2.2 m3/s. A hydraulic jump is formed in the channel,. After which the depth of flow is found to be 2.1m. Find the critical depth, the initial depth of the jump, the energy lost, and the horsepower lost through the jump per unit width of the channel.

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
