List of top Water Resources Engineering Questions on Fluid Mechanics asked in GATE CE

A spillway has unit discharge of 7.5 m3/s/m. The flow depth at the downstream horizontal apron is 0.5 m. The tail water depth (in meters) required to form a hydraulic jump is_____ (rounded off to 2 decimal places).
A 5m × 5m closed tank of 10 m height contains water and oil, and is connected to an overhead water reservoir as shown in the figure. Use \(γ_w=10\ kN/m^3\) and Specific gravity of oil = 0.8
water reservoir
The total force (in kN) due to pressure on the side PQR of the tank is _____ (rounded off to the nearest integer).
A hydraulic jump takes place in a 6 m wide rectangular channel at a point where the upstream depth is 0.5 m (just before the jump). If the discharge in the channel is 30 m\(^3\)/s and the energy loss in the jump is 1.6 m, then the Froude number computed at the end of the jump is _________ (round off to two decimal places).
