you have first to know the thermal conductivity of PPR that you are dealing with. normally, this is in range between 0.1 to 0.24 W/MK .then you apply this formula Q(IN WATTS) =Thermal Conductivity/MK)*A( surface area for the pipe M2 )temperature difference between fluid inside pipe and temprture of pipe surface K)/(thickness of the pipe M)
Curved surface area of a cone = pi*radius*slant length
Differential calculus is concerned with finding the slope of a curve at different points. Integral calculus is concerned with finding the area under a curve.
The answer will depend on shape in question.
Surface Area (Sphere_ = 4 X pi X r^(2) = 4pi r(2) Volume (sphere) = (4/3)pi r^)3)
the formulas for lateral area dont include the figures bases. surface area does.
Lateral area excludes the areas of the top and bottom faces, which are included in the surface area.
Lateral surface area of a cuboid = 2 (Length + Breadth) × Height Lateral surface area of a cube = 4 × Side2
If a is the side,lateral surface area of cube=4a2
true
total surface area is all of the area. ex. for a square pyramid it would be the area of the square on the bottom and the four triangle sides lateral surface area is all the surface area EXCEPT the base. ex. for a square pyramid it would be the area of the four sides of the pyramid. the bottom square is NOT included. for a triangular prism it would be the area of the three rectangle sides, NOT the two triangular sides
surface area is lateral area
The lateral surface area is 565.49cm2
The lateral surface area is 549.78mm2
Lateral Area is the area of the sides of a solid, not including base.
Wrong, it's True. (Apex)
A sphere has only a surface area and no lateral area since it has no base. The surface area is 4(pi)r2.
