Sometimes existing infrastructure limitations, such as chilled water pressure or pump capabilities, play a role in pipe sizing. In such cases, the available pressure drop may dictate the pipe size, regardless of general rules of thumb.

There are many methods to mount a plate/pan inside your fire feature. We’re just going to tell you our favorite way to do things because… well, it has worked well so far! With that being said, these methods may not work in all situations, so put your problem-solving hat on and get creative.

Among mechanical engineers, such as me, a very general rule is about 10 feet per second. https://www.engineeringtoolbox.com/flow-velocity-water-pipes-d_385.html That's when water erosion of metal surfaces starts being significant, particularly when the flow turns, such as in elbows, Tees, and curves in general. It's also when friction loss becomes noticeable and for some elaborate systems of large extent, pumping costs go up. Whether the flow is turbulent isn't of consequence in itself, and it would be nearly impossible to avoid it in most practical systems. Yes, it may be surprising, but water erosion can be a problem, and in general that's different from cavitation, which occurs when the pressure in a liquid becomes lower than the liquid's vapor pressure. Most of that is avoided by keeping the inlet of a pump, for instance, above the Net Positive Suction Pressure (NPSH) specification for that pump. Cavitation can also occur in other applications, such as propellers with liquids. And again, the design parameter there is fluid pressure, not velocity.

In South Africa we use the Guidelines for Human Settlement Planning and Design, or what we just call the (Civil) Red Book. This is a really good resource for smaller projects or quick feasibility estimates.

I have come across various values for maximum flow velocity of water in pipes. At university we were told that 2 m/s is the upper limit where flow becomes turbulent.

Pressure too High? You may experience unwanted noise, usually a hissing sound. You might also find it difficult to dial in the desired flame height using the key valve.

The Platinum Automatic Ignition System delivers superior quality, performance, and value. Expertly engineered, this innovative ignition has been designed and built to be the safest and most dependable way to light fire in both residential and commercial spaces.

Higher velocities can lead to increased pumping costs and potential damage to the piping due to erosion or water hammer. On the other hand, lower velocities result in larger (and more expensive) pipes and may cause issues like fouling or solids deposition due to insufficient turbulence.

Another reason is that sudden changes in velocity in a water system can have potentially catastrophic effects but if we limit the velocity then any sudden change in velocity will have a diminished impact on the system infrastructure.

Pipe diameter and material of construction is also a factor. One must take the volume of water into account. With smaller diameters, such as factory reticulation, 1 meter per second is usually the upper limit to prevent hydraulic shock (water hammer), which can destroy some valves, such as butterfly valves. With larger diameter pipes, such as for wide area reticulation, even 1 meter per second can damage or destroy concrete pipes, so a bypass should be installed to protect valves and piping.

You can have great gas pressure, but if your line is too small, you may not get the desired flame. Think about it like filling up a swimming pool. If you reduce the nozzle size significantly, you may have a ton of pressure, but it’s going to take longer to fill up the pool. You need both pressure and volume to get a great flame. This is why the size of the gas line is so important.

High water pressure can result in leaks, pipe damage and wasted water. High water pressure can be controlled by a PRV installed prior to the water meter.

Water Column is the term used to measure pressure. There are 27.7 inches of water column pressure in 1 PSI of pressure. So 7″wc is about 1/4 PSI. This is the normal pressure that household natural gas is delivered.

Chapter 9 in Volume 2 is about water supply and and it states on page 24: "Velocities in pipes should be approximately 0,6 m/s and should not exceed 1,2 m/s." This is in line with the 1 m/s you've picked up from reports.

The Lockwood Padde Series ES150 is a surface mounted electric strike suitable for use with rim or surface type dead latches. This strike is easy to.

Most metropolitan areas in Canada will require an automatic shutoff for fire pits over 65K BTUs in order to get a permit or certification.

In various planning reports I have read recently, 1 m/s is stated as the upper limit. I could calculate the exact velocity at which water in a specific size and type of pipeline will no longer flow in a laminar way, but for infrastructure planning purposes, this exercise is not required. What would a reasonable value for potable water be? Alternatively, what would the value for raw water (river) be?

In order to get the proper volume and pressure of fuel, you need a gas line that is large enough in diameter to carry it sufficiently. For the most accurate assessment, consult a fuel professional. For a rough estimate, utilize our gas line sizing charts below.

*Make sure the BTUs from your line can supply at least 60-70% of what the burner is rated at. (At 60% capacity, your flame height may be more like 18″ high vs. 24″+ at full capacity.)

As far as I understand, the reason behind the figure is how Reynolds number is calculated and related to turbulent flow.

Generally we want to limit the amount of velocity in a pipeline. One reason is that as velocity increases, the friction increases which in turn decreases the total energy we are delivering to the end user. This also means that all the money we spent adding energy in the pipeline is simply burned off with the friction.

When modelling district heating network, I came across this figure showing recommended pipe diameters with respect to the flow velocity (of hot water). I hope it illustrates how maximum flow velocity should be considered w.r.t. pipe parameters.

There are various pros/cons of Liquid Propane (LP) and Natural Gas (NG). The difference between LP and NG Warming Trends burners are the “jets”. If, down the road, you need to convert from LP to NG or vice-versa, you can do so by purchasing replacement jets from us at $25 each.

The main purpose of the plate or pan is to hold in the media (lava rock, glass, etc). It also acts like the hood of a car, in that it can be lifted up and out in order to access the gas line or key valve underneath. The plate/pan makes installation easier as well.

Installation: Comes pre-installed to the plate/pan unless ordered a la carte. This allows for a hassle-free setup. Powered by (2) AA batteries.
