- Q:how we can design a simple total head tube ??
- A tube with an open ends and connected straight (at right angle) into the side of a pressure container like a pipe or a vessel is called a piezometer. Fluid will rise in the tube equivalent to the static pressure in the container. In a pipe the fluid will probably also be moving and so will have some dynamic energy. If the tube tip has been bent 90 deg. and inserted ( preferably to the center) so that active end is facing upstream, the impact of the moving fluid will convert to additional height of fluid in the tube so that the total head will be the sum of the static equivalent plus the velocity equivalent in feet or meters. That tube is sometimes called an impact tube. The best arrangement is to close the active end of the tube and drill a hole at 90 deg near the end. This allows for the straight tube to be more easily inserted through a small round opening with a sealing gland to stop leakage. This short part can be metal and a clear plastic or glass tube extension fitted to it. A Pitot tube is a combination of the two types of tube and is commonly utilized to measure velocity by subtracting the two heads. It is used in any fluid, water or air, open or contained. However, the Pitot like most other pressure devices usually employs a gage rather than open tubes. The open tubes will limit the amount of pressure to be measured because for each pound of measured pressure (psig), water will rise 2.31 feet.
- Q:How do you prevent plastic tubes from cracking in cold temperatures?
- One effective way to prevent plastic tubes from cracking in cold temperatures is to use insulation or protective covers. These covers help to maintain a consistent temperature and prevent the plastic from becoming brittle. Additionally, choosing plastic materials that are specifically designed to be resistant to cold temperatures can also help prevent cracking.
- Q:Are plastic tubes suitable for vacuum applications?
- Plastic tubes can be suitable for vacuum applications depending on the specific requirements and conditions. Some plastic materials, such as PVC or polyethylene, may not be able to maintain a strong vacuum due to their inherent permeability to gases. However, other plastic materials, like nylon or PTFE, offer better resistance to gas permeation and can be used effectively in vacuum systems. Additionally, the design and construction of the plastic tube, including its wall thickness and reinforcement, play a crucial role in determining its suitability for vacuum applications. Ultimately, it is important to consider the specific needs of the vacuum system and consult with experts to select the most appropriate materials and design for the intended application.
- Q:How do you measure the volume of a plastic tube?
- To measure the volume of a plastic tube, you can use the formula for the volume of a cylinder, which is πr^2h. Measure the radius (r) of the tube by taking the distance from the center of the circular opening to the edge, and measure the height (h) by determining the length of the tube. Plug these values into the formula, multiply π with the square of the radius and then multiply it by the height to calculate the volume.
- Q:where can i find empty plastic candy tubes for sand candy?
- NO NO NO NO NO That is very dangerous. A baby can choke on even a corner of the bag if they get it caught in their throat and it would be very hard to get it out. Never let a baby play with plastic bags or pieces of plastic wrappings. It is too dangerous, no matter what the size of it is.
- Q:How are plastic tubes filled with products?
- Plastic tubes are typically filled with products through a process called tube filling. This involves using specialized machinery that dispenses the product into the tube through a nozzle or pump. The tube is then sealed, usually using a heat sealing method, to ensure product integrity.
- Q:There are so many plastic tubes in the beer brewing process, and the cleaner that comes with the kit is not good enough. I was wondering if anyone has any good tips or tricks.
- Do not use bleach! The flavor leaches into the plastic and goes back into the beer. Use some B-Brite, available at your LHBS.
- Q:I have a pond pump and standard aquarium plastic tubing. I will be drilling tiny holes in equal increments throughout the tubing to release the air. Is there an equation to show the air pressure that will be released through the holes? I would like to know how many holes I need and how far to space them to achieve a certain amount of air pressure to be released from a specified length of tubing.This is a test and will not be done under water. A simple diffuser will not work for this application.Ideally I would like a formula where I can input the following and get a result:Tube LengthTube DiameterPump PSITube Hole SizeTube Hole QuantityTube Hole SpacingResultAirflow per Tube HoleAny help would be greatly appreciated. If you need more information please let me know.Thank you,
- Well, I suppose it could be done, but you would need the pressure at each hole,which is decreasing as the tube length and water depth. And you have so many variables! I also like to calculate such things as you are doing, but this is really over the top! Here is what I would do; Get a measured paper cup (say 1 cup, or 1/4 litre). Experiment with various sizes and number of holes in your tubing, then hold the cup over the coiled tubing, under water at required depth, with air pump running. Measure the time to fill the inverted cup with air. If a 1/4 litre container fills with air in 15 seconds (1/4 minute), you know you are getting 1 litre per minute. Then try other hole configurations to get what you want. This would be more fun, more practical, and will give bettter results. Good luck Bill
- Q:Can duct tape be used to fix flexible plastic tubing? We sprung a leak in the flexible plastic tubing last night and so I am hoping I can just use duct tape to fix the small crack in the flexible plastic tubing. Thanks,Jeff
- Hi, If the water is going through the tube (pressurized) then you can't, if it's an a/c drain tub then you can.
- Q:1995 Honda Civic1.6L V-TECH Motor v4This is a good car there is only one problem the engine overheated and melted the plug wires. I replaced the Part but needs to have plug tubes cleaned out due to melted plastic. I need help from a mechanic expert about this as i do not have the tools to do the job but i could get them tools.
- unless the melted plastic interferes with the new tubes or spark plugs, there is no reason to try to clean the plastic out. if you can get the plugs out and put new ones in and put the wires on with no problem then just leave the residue in there...it won't hurt anything. you are talking about a major undertaking if you want to remove the tubes to clean them. The valve cover has to come off to get to the tubes and the tubes are usually pressed into the base of the head so the head may have to come off as well. you might want to just pull the wires and try to use a rat-tail file down into the tube to scrape away the excess plastic on the inside of the tube (leave the spark plugs in place if you try this so the filings don't get into the engine). Then use a vacuum cleaner to suck the filings out of the tube before you put the wires back on. I'd recommend that as the best thing to do if the burnt plastic is a concern. Otherwise, I'd leave it alone. hope that helps
