maybe have the bleed valve at the bottom of the chamber instead of the top. not sure if it will work though

for this one tank we built the consulting engineer legitamately used 200km/h in his calculation for wind resistance. the chances of such a wind is quite low.

if the a frame design looks anything like in the following picture: then i think you have two major conditions to consider. the first condition is when the load is fully lowered and the second condition is when the load is fully lifted.id like to draw your attention to how much the angle of the...

The bigger pipe will put less back pressure on the pump for the same flow.

Even on smaller boilers this is an issue. The induced draught fan must be run at reduced speed or with a damper partially closed until the flue gas temp gets to acceptable levels. In our case this will be about 160-220 degrees. Trying to run the I'd fan on full output when temps are low results...

oh I see. yeah, I'm reasonably convinced it will require intervention. I tend to solve my problems with technology rather than math though, lol... I must admit I don't have the faintest idea about the math that your using, haha

I'm not sure what you mean

Maybe look up municipal water flow dividers. I think they sound like what you are looking for.

Machine grooves in relevent places on the shaft and use circlips

The ''beam'' is extremely short compared to how wide/deep it is. The way I see it you will not be able to ignore shear deflection because it will have a significant contribution. Plastic usually has a youngs modulus way lower than any steels so the rotation of the rod in the plastic will also...

I might have read the question too quickly. I see my mistake now. the explanation holds though. it will def be ''harder'' to accelerate from 0-1000 m/s, but yes, it is the opposite of what the OP suggests. it seems it won't allow me to edit the answer.

Well, yes, it is harder. You will require a larger impulse to accelerate the same mass from 0-1000m/s. Note that this can either be a small force applied over a very long period of time or it can be a very large force over a small period of time. More fuel will be required and more energy will...

We used spiralwounds on the boiler manholes. General consensus was that if you used it once you chuck em. They get crushed quite badly when you tighten them down. Can't comment on recommended torques though. We tightened them as hard as we could and then flogged them down some more sometimes...

If cost is not an issue I think you should go for the 304 stainless. I worked for a company where we made aluminium radiators and stainless tanks. Aluminium does corrode and it can become quite visible. Sometimes when people want corrosion resistant options that are cheaper than stainless they...

@jim mcnamara let's just say the potato gun is a metaphor for a more generalized type of problem. The problem of throwing something very far, very quickly by burning something else rapidly. Doesn't have to be a gas cycle if the ''industry norm'' isn't gas cycle oriented. Your link is fantastic...
