2.Features of PVC Pipes :
1) Light weight, easy to load and unload: PVC pipe is very light, convenient to handle loading unloading, and installing.
2) Good chemicals and drugs resistance: PVC pipe has its excellent resistance to the erosion caused by acids and alkalines, a great help to the chemical industries.
3) Small resistance to fluidity: The smooth surface reduces resistance to the fluids. Its roughness coefficient is only 0.009, much less than other pipes, Under same discharges, smaller cabibre of the pipe can be uesd.
4) Water quality unaffected: The solution tests on the PVC pipe show no affect on water quality when the water flows through is. It is considered the best piping material for running water works.
5) Simple installation: Very easy to connect, thus much time and laborcost may be saved.

- Q:What is the minimum wall thickness of plastic tubes available?
- The minimum wall thickness of plastic tubes typically varies depending on the specific type of plastic and manufacturing processes, but it can generally range from 0.5mm to 1mm.
- 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:You find this tubing with home cinema equipment cables. It's mounted on the wall and does not need any wall cable grippers or anything.
- ITS A CONDUIT, THEY CAN BE METAL OR PLASTIC.
- 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:Are plastic tubes safe for storing chemicals?
- Plastic tubes can be safe for storing chemicals depending on the type of plastic used and the specific chemical being stored. It is important to consider the compatibility of the plastic material with the chemical to prevent any reactions or degradation. Additionally, factors like temperature, pressure, and exposure to sunlight should be taken into account. It is recommended to consult material compatibility charts and guidelines provided by manufacturers or experts to ensure safe and suitable storage of chemicals in plastic tubes.
- Q:I am using a device to push small volumes (60-100cc) through a plastic tube with a length of approx 24 and a diameter of 1mm or less. I can control flow rate, generally 2-4cc/sec. The liquid has a higher viscosity than water. I am trying to determine the difference in pressure on the piston face (which remains a constant size) using different fluids with slightly different viscosities through tubing of the same length, and differences in pressure using the same fluid through different tubing lengths. Ie; Fluid A and Fluid B through Tube 1, and Fluid A through Tube 1 and 2. The tubes are the same material, same diameter, regardless of length. The pressure used to push the piston remains the same across all fluid/tubing combinations.
- If the flow is not turbulent (no high speeds) and incompressible, and the tube is of circular cross section, then Poiseuille Law flow will ensue. In Poiseuille flow through a cylindrical pipe the velocity is largest along the centerline of the tube and diminishes to zero at the inner wall quadratically with distance r: v(r) = c (R^2 - r^2) with c a constant for given viscosity and pressure gradient ( delta(p) / L ) In Poiseuille flow through a cylindrical pipe the rate of flow (volume/second) is given by Qdot, where Qdot = ( Delta(p) pi R^4 ) /(8 eta L). (where eta is the dynamic viscosity of the fluid) Since the pressure difference Delta(p) is the pressure on the piston face - ambient pressure , let's call this (p - p0) , you have p - p0 = ( 8 eta L) * Qdot /(pi R^4) Using this Poiseuille' s Law you can calculate the pressure on the piston. You say at the end of your question that the pressure used to push is kept constant. In that case the flow rate you measure should be inversely proportional to eta and L.
- Q:Are plastic tubes resistant to heat or fire?
- Plastic tubes generally have low resistance to heat or fire. They can melt or deform when exposed to high temperatures and are considered flammable materials.
- Q:a while back lets say couple of years ago i bought some sweets in a little plastic tube, they looked like little raindrops and were all different colours ... anyone who knows because its driving me insane ... cant find them... thought they werre some like limited edtion by starbust, but i think i am wrong x
- I'm not entirely sure but I know they sell Hard rock ice candies' They look like little sparkly drops, or maybe raindrops. They can come in separated pieces or all attached on a stick (Like a corndog)
- Q:i recently got started with oil paint, and some of my tubes are leaking quite a bit. i seal the cap well, and there are no holes or anything in the tubes. i read that putting the tubes under extreme heat or sunlight can cause them to leak, but i do neither of these things.how do you prevent/solve this?

- Q:What does "DN" and "Dn" mean in plastic pipes? And de?
- DN means nominal diameter or nominal diameter. Is the general caliber of various tube and pipe accessories, with a nominal diameter of the tube and pipe accessories can connect with each other, with interchangeability. It is not a real sense of the pipe diameter or diameter, although its value is closer with the pipe diameter or equivalent;De refers to the outer diameter,DN and Dn mean the same thing.
