For solving network problems of pipes, necessary condition is
n any pipe network, the following conditions must be satisfied: The algebraic sum of pressure drops around a closed loop must be zero, i.e. there can be no discontinuity in pressure. The flow entering a junction must be equal to the flow leaving that junction; i.e. the law of continuity must be satiRead more

See lessThe best side slope for most economical trapezoidal section, is
Conclusion: In summary, the best side slope for most economical trapezoidal section is 60 degrees because it minimizes the cross-sectional area while still satisfying the design requirements.

See lessThe following is not a laminar flow
Rivers/Canals: Rivers and canals are examples of laminar flow. The water molecules move in straight lines and do not mix with each other. This helps to prevent the water from being polluted. These are just a few examples of laminar or streamline flow.

See lessWhen no air is left below the nappe and water stream adheres to the down stream face of the weir, it is known as
Clinging nappe: The process of removal of air continues further and at a certain time, no air is left in the space. The nappe in this state adheres or clings to the downstream side of the weir. Such nappe is called clinging or adhering nappe.

Discharge over an ogee weir remains the same as that of
Concept: Generally, ogee weirs are provided for the spillway of a storage dam. The crest of the ogee weir slightly rises and falls into parabolic form. Flow over ogee weir is similar to flow over rectangular weir, cippoletti weir.

See lessIf velocities of fluid particles vary from point to point in magnitude and direction, as well as from instant to instant, the flow is said to be
In turbulent flow, the speed of the fluid at a point is continuously undergoing changes in both magnitude and direction.

If Cv, Cc, Cd and Cr are the hydraulic coefficients of an orifice, then
Coefficient of Velocity(Cv) is defined as the ratio between the actual velocity of a jet of liquid at vena-contracta and the theoretical velocity of the jet. Co-efficient of contraction(Cc) is defined as the ratio of the area of the jet at vena-contracta to the area of the orifice.
