Q: I am doing a project and i have a plastic tube that need to go in circles so i need to straighten it. Any Ideas? I need this fast please. :): Blow dryer on high or a heat gun on low. The heat gun will be the most likely to work. Not knowing your age I will say that you can get your parents to put it in your oven and set the temp for say 170F or less and heat it for 3-6 min. That will soften it up but if your oven does not go that low forget that method. The oven method would be my last choice. Just thought of one. If you have a rice cooker or steamer that may work if it is big enough. The steam will heat it but not burn it. But again if you are a minor have your parents do it. This you will have to watch and again it would not be my first choice.

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: Plastic tubing is touching compressor (or close to it) and gets hot and brittle. I recoupled a bad spot 1 year ago and it is leaking again. I would like to replace the tubing from the back of the refrig (solenoid) to the water filter. Any ideas on what material to use? I would like to use copper line thru the bottom of the refrig if not all the way to the water filter, but don't know how to connect it to the solenoid. Also would pex (1/4 OD) line be a better (albeit more expensive) choice for this?: You can replace the line with copper. If the connection point is metal you'll want to use a brass compression nut (brass) with a (brass) compression sleeve (know as a ferrules) if the connection point is plastic you'll want to use a nylon compression fitting. The metal ferrules one wont work as you would need to crank the you know what out out it to make it seal, and run the risk of stripping the plastic threads. The nylon takes less torque to seal if that makes sense as its a more dense material. You should be able to get all the parts from a local hardware store or big box store such as lowes or homedepot.

Q: Can plastic tubes be used for packaging cosmetics?: Yes, plastic tubes can be used for packaging cosmetics. They are commonly used due to their versatility, flexibility, and ability to protect the contents from moisture and contamination. Plastic tubes also offer convenience in terms of dispensing the product and can be easily customized for branding purposes.

Q: Are plastic tubes resistant to discoloration?: Yes, plastic tubes are generally resistant to discoloration.

Q: What's the name of that plastic tube used to fold stars?: (1) the straw is bent back;(2) turn left pipe to the lower right;(3) turn the upper pipe to the left;(4) turn the two pipes together;(5) wrap the left tube over the right tube and fold it to the lower right;(6) wrap the upper tube over the lower tube;(7) the two pipes are turned together, with steps (4), repeating steps (4), (5), (6), (7);(8) stick the first angle close to the two pipes;(9) wrap the left tube over the first corner;(10) turn the top pipe down to the bottom;(11) repeat steps (9), (10) fold the tube to the end;(12) pass one of the tubes through the stars;(13) trim after tensioning;(14) complete

Q: Are plastic tubes resistant to impact or pressure?: Plastic tubes can vary in their resistance to impact and pressure depending on the specific type and quality of plastic used. Some plastic tubes can be designed to withstand high impact and pressure, while others may be more prone to damage. It is important to consider the intended use and specifications of the plastic tube to determine its level of resistance.

Q: ...little grinding bits come in.The seal can be O.D. or I.D. and needs to slip on and off fairly easy, just like the seals in the tubes that contain the littler grinding bits Dremel makes.: 1 piece of heat-shrink tubing to insulate your solder connection between EL wire and stereo wire (RadioShack) 1/2 6x32 clear polycarbonate screw to hold end bushing in (this is a recent addition, because the end bushings have come out of some of my blades when they are dueled with. However, these are rather expensive, as screws go. I think I payed about $10 for 50 screws.) hot glue, or silicone for end of blade super glue to glue in top and bottom bushings Note: I don't really like RadioShack all that much. I have a much better electronics store locally that I use that has a better selection and cheaper prices, but you can't order from them online, so I know you should be able to find what you need at RadioShack) That's just for the blade.

Q: PVC plastic pipe in the underground, what need to diameter, the hoop and flange is a kind of thing?: The flange is the part that connects the pipe to the pipe and is connected to the end of the pipe. Flange connection or flange connection, is defined by the flange, gasket and bolt connection between the three sealing structure of the detachable connection as a combination of group pipe flange refers to the pipeline installation of piping flange, used in equipment refers to equipment import and export flange. The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Flange, threaded joint flange and welding flange.

Q: Can plastic tubes be used for hydroponic gardening?: Yes, plastic tubes can be used for hydroponic gardening. They are commonly used as a component of hydroponic systems, serving as a conduit for nutrient-rich water to flow to the plants' roots. Plastic tubes are durable, easy to clean, and resistant to water and nutrient solutions, making them a practical choice for hydroponic gardening setups.
