Three point bending is better than tensile for evaluating the strength of ceramics. It is got a positive benefit to tensile for evaluating the strength of ceramics.
Answer:
C. 1 ft long with a weight of 1 lb
Answer:
the sun gives off light while at the same time gives off heat. the shoe box cooker takes that heat and light and reflects it around the shoe box. then the heat settles down into whatever is in the shoe box. the heat after being reflected around the shoe box is magnified by the foil wrapped in the box thus allowing the food or drink to be heated. the foil is a conductor of heat because it is metal .

Answer:
Rate of heat loss per unit length of pipe, q' = 767.01 W/m
Explanation:
Let q' be the Rate of heat loss per unit length
Let q be the Rate of heat loss
q' = q/L
Where L is the length of the pipe
Diameter, D= 0.6m
The rate of heat loss q is given by the formula: q = Sk(T₂ - T₁)
Where k is the thermal conductivity of the concrete at 300 K
k = 1.4 Wb/m-K (at 300K)
And S is the shape factor given by the formula:
S = 2πL/ ln(1.08w/D)
S = (2π*L) / ln(1.08*1.75/0.6))
S = (2π*L) / 1.147
S = 5.48 L
q = 5.48L*1.4(400-300)
q = 767.01 L
q' = q/L
q' = 767.01L/L
q' = 767.01 W/m
