### Overflowing water flow between two prisms

I have system as seen in the figure. The pump will supply constant volumetric flow rate and the water will fill the first rectangular prism. I couldnt find the water height after water starts to ...

### How can depth of flow in a supercritical flow get affected when the flow passes through a constriction of width less than the critical width?

When a supercritical flow approaches a constriction having a width less than the critical width does the depth of supercritical flow decrease upstream so as to increase specific energy? If it does ...

### Tipped triangular weir

Can someone tell me what influence an angled wall has on the flow over a triangular weir compared to a "normal" vertical one if the wall is angled against the upstream as in the picture?

### How does decreasing the cross-sectional width of a channel impact steady flow?

The continuity equation states that for a constant mass flow rate, if the cross sectional area of a channel is decreased, then velocity is increased. What happens if the channel has high walls and is ...

### How can I size a sump area to act as an energy dissipator?

I have a proposed stormwater design which will necessitate some very large diameter pipe installed near the surface to minimize constructability issues. However, near the end of the run, it will be ...

### Turbulent boundary layer development in channel flow

I'm currently working on my Bachelor's thesis about the numerical simulation of a turbulent air flow through a rectangular channel. As part of that I'd like to compare my results to empirical ...

### The mechanism of submerged hydraulic jump

Is there a mathematical analysis of the submerged hydraulic jump, such as under what condition it is formed, the speed and trajectory of the circular flow therein, etc.? Is there a good mathematically ...

### Open Channel flow with pressure losses - flow depth?

In a horizontal channel that feeds off a river, does the head/pressure loss due to friction, turns etc in the channel translate to a drop in the water level between its inlet and outler? If so, could ...

### How to make sure a pipe does not take all of the water from a stream?

I am trying to design a pipe which takes water from a river and transports it to a reservoir. However, I do not want my pipe to take all of the water from stream, because that will create all sorts ...

### Ideal funnel design for powders

I'm designing a funnel/bottle for a powder. My goal is to have all of the bottle's powder contents come out when inverted. However, the powder has a tendency to stick to itself (like flour or brown ...
