10 inches of fiberglass insulation Provides how much of an R factor?
r-30
10 of fiberglass insulation provide how many R?
10 inches corresponds to about R-38.
What value does 10 insulation give?
If you are referring to the R value of insulation, then 10 would be the 'thermal resistance' value of the insulation. A value of 10 is about what 3 1/2 inches of fiberglass batt insulation would give you. That is what you might put within your exterior walls if you are using wood studs. The higher the R value the better insulation you will have. When you add up all of the R values of the materials that make up your exterior wall you will get your total value. Depending on where your building is located, and the climate in that area, you will need to adjust your insulation accordingly.
What is the mechanical advantage of a first-class lever in which the fulcrum is 10 inches from the resistance and 40 inches from the effort?
answer is 4
What is the mechanical advantage of a first class lever in which the fulcrum is 10 inches from the resistance and 40 inches from the effort?
answer is 4
Basketball board dimension?
72 inches by 42 inches. 72 inches by 48 inches. For outdoor use backboard surface area is reduced and the top and base is contoured to reduce wind resistance.
Which lever would have more mechanical advantages than one with a resistance arm of 3 inches and an effort arm of 6 inches?
a lever with an effort arm of 2 inches
If attic has five-inches of loose-fill fiberglass . how many inchea of TAP insulation shouldbe added to obtain an R-38?
In the U K 250 millimeters /10 inches is the required limit so if you 5 inches just now you will have to add 5 inches on top the nearest size to that is 150 mm/ 6 inches
What is the r value of 8 inches of fiberglass insulation?
technically unfaced fiberglass insulation has an r value of 21 for 6 inches but that's if its perfectly installed, no gaps, no crushes, no air moving through it, no moisture, and its completely in contact with the interior heated surface. Since its unfaced, we assume it will have moisture and air moving through it and an average installation, it's likely R-13 or less.
Why don't bends in a wire effect its resistance?
This is kind of sticky to explain. A flow of electrons is exactly like distance in geometry - the shortest distance between two points is a straight line. Distance in wiring is increased resistance. In a circuit board 8 inches square, the fact that the wire has to make a bend has negligible effect on the resistance. In a spring reverb unit, the current is going through a tightly wound coil that is eight inches long - but actually represents about 30 inches of wire. That slows the current down to an extent because of the added resistance.
What is the spec for resistance in spark plug wires for an 87 Chrysler fifth avenue?
