542..A hydraulic jump was established in
the river. The depth before the jump
measured 3.38 cm and the depth after the
jump was 11.46 cm. The width of the river is
31.2 cm. Write the type of the jump when
the discharge is 0.0162 m3/s.
10.67 In a rectangular channel 4 m wide with a
flow of 7.65 m/s the depth is 0.4 m. If a
hydraulic jump is produced, (a) what will
be the depth immediately after it?
(b) What will be the loss of energy?
8.
A hydraulic jump occurs in a rectangular channel and the
depths of flow before and after the jump are 0.5 m and
3.0 m. Calculate (i) the critical depth and (ii) power lost
per unit width of channel.
