The available head of a Francis Turbine is 100 m. The velocity of the flow at the runner inlet is 15 m/s. Find the flow ratio.
In which type of turbine are the turbine inlet whirl velocity and inlet jet velocity equal in magnitude?
If a pipe with an end cap nozzle discharges a jet of water with velocity V, and the jet hits a plate moving towards the nozzle with velocity V/2, then the discharge of the jet hitting the plate would be:
A trapezoidal channel is 10.0 m wide at the base and has a side slope of 4 horizontal and 3 vertical. The bed slope is 0.002. The channel is lined with smooth concrete (Manning’s n = 0.012). The hydraulic radius (in m) for a depth of flow of 3.0 m is
A 1:50 model of a spillway is to be tested in the laboratory. The discharge in the prototype spillway is 1000 m3/s. The corresponding discharge (in m3/s, up to two decimal places) to be maintained in the model, neglecting variation in acceleration due to gravity, is ____.
The top width and depth of flow in a triangular channel are 4m and 1 m respectively. The measured velocities on centre line at the surface, 0.2 m and 0.8 m below the surface are 0.6 m/s and 0.4 m/s respectively. Using 2-point method of velocity measurement, the discharge (Q) in the channel in m3/s is,
A short reach of a 2 m wide rectangular open channel has its bed level rising in the direction at a slope of 1 in 10000. It carries a discharge of 4 m3/s and it’s Manning’s roughness coefficient is 0.01. Flow is gradually varying. At a certain section in the reach, depth of flow was measured as 0.5 m. The rate of change of water depth, dy/dx at this section is ____. (use g = 10 m/s2) Round off to 4 decimal places
