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:how long will cigars keep in tubes?: Depends on where you live. Florida, Louisiana, Mississippi, or other states that are very humid most of the time will keep them for a good long while. (Assuming you don't have them in an air conditioned place all the time that dries the air). If you were in Arizona or California or somewhere like that with very dry conditions most of the time; they will be noticeable drier in only a week or so. The tubes are really more just for presentation (like wax on a whiskey bottle) than they are for preservation. Ideal for cigars is around 75 deg F and 70% humidity. Compare where you have them to that to guage their longevity without proper storage. A ziplock bag with some pieces of dried fruit (apricot, peach, etc) is one home remedy for cigar storage, but I can't speak for it's actual effectiveness. The bag itself probably does most of the actual preservation. If they will fit, you can just get a large mason jar and buy these disposable humidty packs from a cigar company or online. Tear the top off of the envelope and place inside the jar with the smokes. Only about $8 invested and you will have pretty good preservation for at least 6 weeks (or until you put in a fresh pack).

Q:What is the minimum diameter of transparent plastic tubes?: The minimum diameter of transparent plastic tubes can vary depending on the specific type of plastic and manufacturing process, but it typically ranges from around 1 millimeter to 10 millimeters.

Q:Can plastic tubes be used for storing petrochemicals?: Yes, plastic tubes can be used for storing petrochemicals. Plastic tubes made from materials such as polyethylene or polypropylene are commonly used for storing and transporting various petrochemicals due to their resistance to corrosion and chemical degradation. These tubes provide a cost-effective and reliable solution for safely containing and preserving petrochemical substances.

Q:instead of using ridgid conduit can polytubing or irrigation vinil pipe be used as an option or cable can just run bare on concret on a house been build up of concret wall in and out ?: In my years of experience, and inspector will fail that in a heartbeat. The Irrigation tubing is not made to run wires through, and the wire could get caught on the tubing , and the wire could dig into the tubing as it is soft and pliable. Also, when you pour your concrete on top of the tubing, the tubing will flatten with the weight of the concrete, causing you to have to remove the concrete to make any repairs to the wire. Defeating the purpose of using conduit in the first place. Use the gray PVC non-metallic conduit, the fittings and the pipe are designed to have wires run through them, and the conduit will not crush under the weight of the concrete poured over it. If you are going to do the job, do it right, and you will save money in the long run.

Q:What are the environmental implications of using plastic tubes?: The environmental implications of using plastic tubes are significant. Plastic tubes are typically made from non-biodegradable materials like polyethylene or polypropylene, which means they can persist in the environment for hundreds of years. Improper disposal of plastic tubes, such as littering or landfilling, can lead to pollution of land and water bodies. They can also contribute to the growing problem of plastic waste in oceans, harming marine life through ingestion and entanglement. Manufacturing plastic tubes requires the extraction of fossil fuels and the emission of greenhouse gases, contributing to climate change. Additionally, the production process involves the use of chemicals and energy, further depleting natural resources and increasing carbon footprints. Considering these environmental impacts, it is crucial to explore alternative materials or recycling options to mitigate the harmful effects of plastic tubes.

Q:What are the common thicknesses for insulation plastic tubes?: The common thicknesses for insulation plastic tubes can vary, but typically range from 1/8 inch to 1 inch.

Q:Are plastic tubes suitable for agricultural irrigation?: Yes, plastic tubes are suitable for agricultural irrigation. They are durable, lightweight, and resistant to corrosion, making them a cost-effective and efficient option for transporting water to crops. Additionally, plastic tubes can be easily installed, maintained, and adapted to different irrigation systems, making them a popular choice among farmers worldwide.

Q:PVC plastic pipe in the underground, what need to diameter, the hoop and flange is a kind of thing?: The hoop is usually used to make commonly known as pipe clamp, hose fastener with temporary fasteners, also can be used for temporary plugging. Flanges are also called flanges or flanges.

Q:It is for a plastic tube that goes from the engine of my motorized paraglider to the inlet of my new gas tank. The plastic is a little too tight and I can't warm it up with a flame because of gasoline that may still be in the engine.: Then try going the other direction and freezing the smaller tube. That may make it shrink enough to fit.
