Light concrete can have a conductivity as low as 0.1 watts per meter-kelvin, making it a good insulator. Assume the slab is made of dense concrete with a conductance of 1.2 watts per meter-kelvin.Determine the thickness of the material and convert to meters. Thermal conductivity is a property of a material that tells you how easily heat will conduct through the material.

Listen to the audio pronunciation of Watt per meter-kelvin on pronouncekiwi. It is also known as watts per meter per kelvin, watt per metre per kelvin, watts per metre per kelvin. watt per meter kelvin [W/(m*K)] 5.188732 E+02: calorie th per centimeter second degree Celsius [cal th /(cm*s*°C)] watt per meter kelvin [W/(m*K)] 4.184 E+02: square foot per hour (ft 2 /h) square meter per second (m 2 /s) 2.58064 E-05: clo: square meter kelvin per watt (m 2 *K/W) 1.55 E-01 Also, what does a materials' thermal conductivity tell me? To design comfortable and ecologically sound buildings, architects and engineers make use of the thermal properties of materials. He has a vast area of expertise including cooking, organic gardening, green living, green building trades and many areas of science and technology.

Conversion to SI and other common units . The conductivity of the slab increases with conductance and decreases with thickness. In buildings, you are often concerned with stopping heat flow, or insulating.

Watt Per Meter Per Kelvin (W/m-K) has a dimension of MLT-3 Q-1 where M is mass, L is length, T is time, and Q is temperatur.

This unit is commonly used in the SI unit system.

Heat would have a harder time flowing through a thick slab than a thin slab. Hunker may earn compensation through affiliate links in this story. (General Physics) a measure of the ability of a substance to conduct heat, determined by the rate of heat flow normally through an area in the substance divided by the area and by minus the component of the temperature gradient in the direction of flow: measured in watts per metre per kelvin. The denser the concrete gets, the more conductive it is to heat. Find out information about Watt per meter-kelvin. Notice that the thicker the material is, the higher the R-value is. Light concrete can have a conductivity as low as 0.1 watts per meter-kelvin, making it a good insulator.

Dense concrete can have a conductance as high as 1.8 watts per meter-kelvin. Thank you for helping build the largest language community on the internet.

Small values are better.There is one square meter from the insulation.The temperature difference is one degree Kelvin.The value is the thermic energy passing through in Watt."

Re: What exactly is a Watt per meter-Kelvin (W/mK) Date: Tue Jan 17 11:27:28 2012 Posted By: Adrian E. Popa, Retired Laboratory Director Area of science: Physics ID: 1326414087.Ph A piece of material with a conductivity K and thickness L has a conductance of C = K/L, which indicates how well heat can flow through a specific piece of that material such as a wall. Watt per meter-kelvin synonyms, Watt per meter-kelvin pronunciation, Watt per meter-kelvin translation, English dictionary definition of Watt per meter-kelvin. Assume the slab is made of dense concrete with a conductance of 1.2 watts per meter-kelvin. Label the thickness L.Calculate the conductivity. More of a given material makes a better insulator.Be sure not to confuse conductance with conductivity.
