Q: a. ultraviolet (germicidal light)b. 121 C at 15 psi for 15 minutesc. 160 C for 2 hoursd. all are correct: If it were a Glass tube the answer would be A. UV Light does not go through glass well and would not kill much. If it is a plastic tube, D.

Q: Are plastic tubes suitable for pharmaceutical compounding?: Yes, plastic tubes are suitable for pharmaceutical compounding. They are often made from materials that are resistant to chemical reactions, and they can provide a secure and hygienic storage solution for various pharmaceutical ingredients and compounds. Plastic tubes are also lightweight and easy to handle, making them convenient for both compounding and dispensing purposes.

Q: Are plastic tubes flexible or rigid?: Plastic tubes can be either flexible or rigid, depending on their composition and intended use. Some plastic tubes are designed to be flexible, allowing for bending and manipulation, while others are rigid and inflexible, providing structural support or containment.

Q: My two young female gerbils are chewing on the CritterTrail plastic tubes I have connected to the cages. They have tons of chew toys, food, and space. I've placed two toilet paper holders in their large nest area. It's helped a little, but they still chew on the plastic tubes. Which is VERY noisy, and I don't think chewing on plastic is good for them compared to natural wood.: You would just be better off getting a 20 gallon long tank or a bin cage. The cage you have now is too small and it would be hard to safely connect it to a tank.

Q: Im making moonshine but not for drinking for fuel. I know that its a bad idea to distill with plastic if your gonna drink it but will it be ok for fuel?: I wouldn't Plastic is made of hydrocarbons, and alcohol is a hydrocarbon - under the chemical principle of like dissolves like I would think the alcohol could leach chemicals in the plastic or dissolve it. If you leach extra chemicals it ruins yer shine!

Q: There is a white plastic tube outside the tank. How can I use it?: The black button is to adjust the amount of bubbles at the outlet. If you take it off, you may not get bubbles out of the water outlet. If your pump is big enough, it doesn't matter if you take it off.

Q: How do plastic tubes perform in low-pressure applications?: Plastic tubes generally perform well in low-pressure applications. They are lightweight, flexible, and have good resistance to corrosion and chemicals. However, their performance can vary depending on the specific type of plastic used and the application requirements. It is important to consider factors such as temperature, pressure, and compatibility with the fluid being transported when selecting plastic tubes for low-pressure applications.

Q: Also when a cell is hypertonic to its environment does that mean the environment is hypotonic to the cell?: If the tube shrinks, water must be going out of the tube, and this must be occurring because there is a concentration gradient across the tubing. However, both sides start with distilled water, so the water on both sides should have the same (low) amount of dissolved substances. Presumably the shrinkage is occurring over a period of hours or days? My guess would be that something is getting into the water in the cup - this could be dissolved matter from floating dust or bacteria, but more likely are gases from the air. Distilling water would degas it - oxygen, nitrogen, and CO2 would be removed. However, these gases, most significantly CO2, will redissolve in the water if it is left in air (carbon dioxide dissolves to make a solution of carbonic acid). In addition, any contaminants that persisted through the distillation would be concentrated when the cup water evaporates, though this is likely to be a small change due to the high purity of distilled water. You are correct about your second question.

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: Are plastic tubes suitable for vacuum applications?: Plastic tubes can be suitable for vacuum applications depending on their material composition and design. Some plastic tubes, such as those made from materials like polytetrafluoroethylene (PTFE), are highly resistant to chemical and thermal degradation, making them suitable for vacuum applications. However, it is important to consider the pressure and temperature limits of the specific plastic tube being used to ensure it can withstand the desired vacuum conditions without deformation or failure.
