Is there an algebraic formula for determining an angle of reflection using only the angle of the ray and the angle of the wall?
Let r be the angle of the ray, and R the angle of reflection.If the wall is flat (i.e., if its angle is 0), then we know that r + R = Pi/2.Now suppose the wall has angle w. Then rotate the diagram by -w,so that the wall is now flat again, and the angles of the ray and itsreflection are now r - w and R - w, respectively.We then have (r - w) + (R - w) = Pi/2, which should give you enoughinformation to find R.

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.
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.
How thick is r 5?
"R" is a value associated with heat penetration. The thickness of a material (for example, typical pink panther insulation) of any "R-value" will vary. If, for example, your wall space involves either a 2"x4", 2"x6", or even 2"x8" wall space then the material you insulate with will, of course, vary in size, however the "R-value" of your material will remain its rated value.
What is the recommended R value for roof insulation?
R 13 for 3.5" wall cavities, R19 for 5.5". R30 for blown in insulation and batts in ceilings.
90 square meters is equal to?
A galvanized steel wall is superior to plywood. A fiberglass (polymer) wall is far superior to both. Good luck with your pool.
How thick a concrete wall would be needed to give the same insulating value as 3 and a half inches of fiberglass?
Poured concrete has an R value of about 0.08/inch. Fiberglass batt has an R value of about 3.14/inch (blown fiberglass wall insulation is about 3.2/inch). From these values we can calculate that the equivalent insulating thickness of concrete would be about 3.5x3.14/0.08 = 137.4 inches. Note that concrete blocks have a somewhat better insulating value due to the incorporated air pockets. A 4" concrete block has an R value of about 0.2/inch An 8" concrete block has an R value of about 0.15/inch A 12" concrete block has an R value of about 0.1/inch

What is the formula for heat flow per unit time through a single layer wall?
Heat flow per area per time = (delta T) / R delta T = difference in temperature between the two sides of the wall area = area of the wall or part of the wall under consideration 'R' = "R"-value of the construction materials and/or insulation that makes up the wall. Intreresting how it's the direct analog of Ohm's Law for electrical voltage (delta T), current (heat flow per time), and resistance ('R').
Is dry wall an insulator?
While drywall, or gypsum board, does give insulation value it is not a high amount, a 1/2" piece of drywall will only raise the r-value by .45, if you are looking to improve the insulation of a wall you are much better off using rigid foam insulation. An extruded polystyrene board, that's Styrofoam, of 1" thickness gives you an R-value of 5.00, which is over 5 times greater per inch than that of drywall. You can further improve the insulation value of a wall by add some kind of batt insulation in-between the studs.
