Hydraulics Questions Set 3:
The Reynolds number for turbulent flow is?
Solution:
Calculate the section factor of a triangular channel section having side slope 1H:4V and depth of 8 m.
Solution:
When the Mach number is less than unity, the flow is called
Solution:
What are the three basic principles of fluid mechanics?
Solution:
The strength of a hydraulic jump is indicated by:
Solution:
The discharge and velocity of water in a rectangular channel are 75 m3/s and 5 m/s respectively. If the hydraulic depth is 3 m, calculate the hydraulic radius.
Solution:
A 4m wide rectangular channel, having bed slope of 0.001 carries a discharge of 16 m3/s. Considering Manning’s roughness coefficient = 0.012 and g = 10 m/s2, the category of the channel slope is
Solution:
A hydraulic jump takes place in a triangular channel of vertex angle 90o, as shown in figure. The discharge is 1m3/s and the pre-jump depth is 0.5m. What will be the post jump depth?
(Take g = 9.81 m/s2)
Solution:
In a Pelton wheel, if the outlet velocity angle of the jet is 90 degrees (right-angled), what is the outlet whirl velocity of the jet?
Solution:
A horizontal jet of water with its cross-sectional area of 0.0028 m2 hits a fixed vertical plate with a velocity of 5 m/s. After impact the jet splits symmetrically in a plane parallel to the plane of the plate. The force of impact (in N) of the jet on the plate is
