    What to do with 1 year+ expired bleach?

    Guess I better check the expiration date on those U-238 pellets I bought on Amazon last year.

    What to do with 1 year+ expired bleach?

    It is OK to put it down the drain 1 cup at a time in the wash so why not pour it down the drain in dilution unless you have a septic tank. Can't imagine it being considered hazardous as it is an oxidizer, right? So it is going to find some yummy turds to oxidize before it gets to the waste...

    Vortices and turbulence in square vs round pipe

    Thanks for the reply. Dang if that doesn't look like the front end of a rocket mass heater. This looks a lot like one of my designs but his is much better. Don't know why he has fins on the side of the burn box though. The reason I want to induce a vortex is to increase burn efficiency. If...

    Vortices and turbulence in square vs round pipe

    Glad her surgeries went well. Hopefully I only need one as I fell hard on that hip years ago damaging the socket and it finally caught up with me. Got to where I could not even ride a bike and I gained 40 pounds. I never was good at attention to details and I was trying to use the insert image...

    Vortices and turbulence in square vs round pipe

    Inserting images is a booger here. Here is a Rocket Mass Heater diagram.

    Vortices and turbulence in square vs round pipe

    Regarding swirl: I want high velocity but I want the gases to spend some time in the pipe for the secondary burn. There is some smoke in the stream when it leaves the horizontal burn chamber the vertical pipe is well insulated and the high temperature will complete the burn, eliminating almost...

    Vortices and turbulence in square vs round pipe

    Thanks for posting. I was hesitant to post as I have too many unknowns but was still was hopeful for some generalities Height is 36-48 inches. Material will be cob-like, rough like concrete pipe. I can only guess the velocity. What is the velocity of a wood stove draft, I am guessing 10-15 fps...

    Vortices and turbulence in square vs round pipe

    Greetings, I am about to start experimenting with misnamed rocket stoves and rocket mass heaters. I say misnamed because I think the velocities are too slow to be rocket science. (Why would I experiment with these? Because I have cement, perlite, and reinforcement materials at hand and I just...
