How to Convert u-value to r-value?
To convert U vals To R Vals 1/u = r val
What is g equals rz for r?
In the equation g = rz, r represents a variable or a constant value. The specific value of r would need to be provided in order to determine its numerical value in the equation.
In the equation of r 14 39 what is the value of r?
R+14=39
Is r-value good or bad?
it is a good thing i think R Value is the thermal resistance of a given material. The higher the R Value the more thermal resistance and the better the insulation. So, an R48 roof system is warmer than an R32 roof system. All insulation materials are rated by their R Value. An inch of rigid insulation has a higher R Value than an inch of fiberglass insulation. Check with the insulation manufacturer for the R Value.
What matierals are spacesuit made out of?
Aluminized mylar and much more stuff. For more details check out nasa
Is there such a thing as an inexpensive reflective mirror finish sheet material that may be folded like cardboard cut with scissors is fairly rigid heat and weather resistant?
Except for not being very rigid, aluminized mylar is the closest material to what you describe, so I would suggest a composite, in which aluminized mylar is bonded to some other material that will give you the degree of rigidity that you need. Cardboard would not be that good a choice since it is not weather resistant, but possibly another layer of plastic would work.
Why is Mylar tape used in fiber optical cable?
There are a few reasons that optical fibers are wrapped with aluminized Mylar. The Mylar acts to reduce signal loss by reflecting lost light back into the fiber, rather than absorbing or refracting it. It also serves to physically reinforce the fiber, even though optical fibers are relatively robust on their own; the wrapping of aluminized Mylar tape serves as a buffer to physical friction, shock, and pressure (as seen during handling and installation), adds some strain relief/protection (as the fibers typically are least resistant to strain), and also adds some measure of environmental protection, to slow degradation of the fiber from environmental contaminants near the ends, where the cable bundles "break out" for connection to endpoints or repeaters.
How does the International Space Station stay cool?
The temperature on the International Space Station (ISS) can be as high as 121 C and as low as -157 C. To tackle this, the ISS has Multi Layer Insulation (MLI). The reflective silver layer is aluminized Mylar. The copper-colored material is kapton, this is a heavier layer that protects the sheets of fragile Mylar. Mylar is aluminized so that solar thermal radiation can't get through it. Hot air that doesn't rise, heat doesn't conduct, radiators too cold for liquid water. But thanks to the Station's efficient integrated thermal control systems, the crew don't have to worry about staying cool on the ISS. Type your answer here...
What was the Apollo 11 lunar module made of?
The LM manned compartment was made mostly of a thick aluminum foil (an astronaut's boot could easily have kicked a hole in it!) The frame supports were aluminum rods. The LM decent stage was covered in aluminized mylar.
How do you make a fake mirror?
It depends on the purpose. One way to make an object that appears to be a mirror for the stage would be to get some shiny aluminized mylar and stretch it tight over a frame. This would appear to be a mirror, but would be much lighter (and would avoid any breakage hazard).
Name the first communication satellite launched by the US?
Telstar, the first dedicated communications satellite, was launched on July 10, 1962. Earlier satellites (that merely reflected or repeated signals) were the aluminized Mylar balloon "Echo I" and the Philco satellite "Courier 1B", both launched in 1960.
What is the density of aluminized steel?
The density of aluminized steel is 2710. Additionally, the density of its counterpart, carbon steel, is slightly different at 2833.
How is plastic aluminized?
Plastic is aluminized with the use of vapor deposition. It does not need base coats, much in the manner that glass optical element are coated.
How do you bond mylar?
THF (tetrahydrofuran) is the most typical solvent for Mylar.
What does PAR mean in lighting?
Parabolic aluminized reflector
What is the difference between T125 and T140 aluminized seel?
T1-25 and T1-40 are coated with the same coating, but T1-40 is a heavier (thicker) coating weight. The US specification for Aluminized Steel is ASTM A463, There are three US producers of Aluminized Steel: AK Steel, Arcelor Mittal, and Wheeling-Nisshin.
