How much roof area will a standard package of shingles cover?
The most common shingles (three tab), come three packs per 100 square feet or a 10 foot by 10 foot area. The timberline shingles can come in 4 packs per square, and high end shingles can be 5 or 6 packs per sguare.
How High Should An 11 Year Old Boy In Fifth Grade Be Able To Jump?
About one foot.
How many square feet will one yard of mulch cover?
Well 1 sq yard of much will cover 325 square ft or so. That is if you have the mulch 1" High. Its recommended to be 1"-1.5" But your probably not going to get it exact at 1" High of mulch so id go with 300 sq ft.
How many bricks do you need to build a brick wall 25ft long 2ft high?
There are different sizes of brick. You will need to know how many bricks are in a square foot, including the mortar joint.
How many eight foot long 2 x 4's will you need to build a wall eight feet high and twelve feet long?
Okay, this requires a little simple math and some three dimensional thinking. For the fence (wall) planks alone, you will need 55 eight foot 2 x 4's. For a simple box frame you will need another 8. 55 + 8 = 63 The problem is, the fence (wall) will not be free standing. You'll need three twelve foot 4 x 4 posts (twelve foot long, because four feet of them will be set into the ground.
What is refractory insulation?
Refractory insulation is defined as insulation for extremely high temperatures. The threshold of temperature of insulation for refractory insulation is > 815 Celsius.
What is insulation co-ordination in high voltage engineering?
To provide optimal insulation to high voltage equipments.
Does a high rating mean lots of insulation or little insulation?
It depends what you mean by a 'high rating'!If you mean a high 'voltage rating' then, yes, you will require thicker insulation. But if you mean a high 'power rating', then, not necessarily, because the voltage can be low, while the current is high.Remember, the thickness of insulation depends on the voltage, while the type of insulation (how it withstands higher temperatures) depends on the current.
What material would be safest to use as an insulator to use to cover electrical wires?
When selecting a material for an insulation factor it has to be balanced between flexibility and its insulation properties. Glass would be an excellent insulator but in the electrical field hard to pull through conduit and bending without damaging the insulation. Cross-linked polyethylene fits both the conditions for a wire insulation. The insulation has a high insulation factor plus the ability to bend without damaging the insulation and can operate in a 90 degree C temperature range.
How high is a foot?
a foot high
What is the optimum insulation resistance for 11kV UGcables when tested by 5000v insulation megger?
High voltage cables with this high an insulation factor are usually given a Hi Pot (High Potential) test and not meggered. The potential has to be higher that the working voltage of the cable to be effective when checking for insulation or connector breakdown.
What is the best insulation to use for bathroom walls?
The best insulation to use for bathroom walls is closed-cell spray foam insulation. It provides a high level of moisture resistance and thermal insulation, making it ideal for bathrooms where humidity levels are high.
If earth's angle of inclination was 0 how would insulation change in High Level Alberta?
If Earth's angle of inclination was 0 degrees, there would be no change in the insulation levels in High Level, Alberta. Insolation (incoming solar radiation) is more influenced by variations in solar angle, day length, and cloud cover than by Earth's axial tilt. Therefore, insulation levels in High Level would likely remain relatively constant throughout the year.
Can mold grow in insulation?
Yes, mold can grow in insulation if the conditions are right, such as high humidity or moisture.
How many bricks are needed to build a 6 foot high wall to cover 43560 square feet?
It depends on the one brick size
Is there a high demand for workers on insulation jobs?
Typically, companies handle their own insulation. There are many types of insulation, pipe, wall, and attic insulation are just a few. Construction companies, and plumbers usually do their own installation of insulation.
Are bad conductors of electricity used to cover electrical wires?
No, materials with a high insulation value factor are used to cover electrical wire to provide a barrier from the wire shorting out to ground. By using the term "bad conductors" states that there is conductivity to a degree.
