For the truss shown in figure, find the force in member BE:

A portal frame is shown in the figure below.Degree of freedom of the frame is:

For the catchment area as shown in figure and run off coefficient (K) for each area, the average runoff coefficient is:

The peak of a flood hydrograph due to a 1 hour duration isolated storm in a catchment area is 240 m³/s. total depth of rainfall is 80mm. Assume a constant flow of 15m³/s and ϕ index to be equal to 5 mm/hr, then the peak of 1-hr UH for the catchment (in m³/s) is :

A hydraulic structure is designed for 70 years recurrence interval design discharge. What is the risk factor that the flow capacity will be exceeded during future 25 years period?

If irrigation efficiency of a 20 ha field is 84% and conveyance losses from the canal outlet is 10%, then the volume of water required at the canal outlet, for supplying 8 cm water depth in the field:

A most efficient channel section of trapezoidal cross section is required to carry a maximum discharge of 20.5 m³/s. Slope of channel bottom is   and value of chezy’s coefficient C = 72 . Determine the value of manning’s coefficient ‘n’ taking the velocity of flow as obtained by chezy’s equation for open channel flow.

What is the uplift pressure head as per Lane’s theory for the given cross section of weir?

Critical state of flow through a channel section does NOT occur under which of the following conditions.

An aircraft is moving horizontally with a speed of 216 kmph. The total wing span of the aircraft is 10 m. It has a chord length of 1m. The total aerodynamic drag force acting on the wings is 3 kN. Drag coefficient and power required for the flight (kW) are respectively. (Take density of air as 1.2 kg/m³).
