How does a grain moisture tester work?
Moisture meters use what is often referred to as the capacitive method or RF dielectric method. With this method a radio signal at a specified frequency is sent through the sample. As water interacts with radio waves (that's how your microwave oven works) it is possible to determine the moisture content by measuring how much the radio signal is changed by the sample. The effect that the sample has on the radio signal is termed the dielectric constant, and it increases proportionally to the moisture content. There are a number of other factors that have an effect on the dielectric constant, perhaps most notably sample density and temperature. These two factors are measured and corrected for in advanced moisture meters.
What 2 factors speed up evaporation?
Heat, altitude, and moisture content in the air are factors which may effect the speed of evaporation.
What is in Cooling Fins on A Radiator?
Radiator have metal fins which increases total surface area of the metal body which cooling effect and hence increase the efficiency to maximum cooling effect.
How subcooling increase the COP of vapour compression refrigeration?
The sub-cooling or under-cooling in the saturated liquid line increases the refrigeration effect or cooling effect, thus the COP of VCR system increases.
What is a good effect of electric fan?
it can give a cooling air
Effect of moisture content on solid waste energy determination?
effect of moisture content on solid waste energy determination and principle of bomb calorie meter??
How does moisture evaporating from major bodies of water effect weather patterns?
the moisture provides heat to the oceans so without it, the water is cool and usually results in sea breeze, thus cooling the atmosphere
What is drier?
It removes the moisture that builds up in an air conditioning system from constant expansion and compression that creates the cooling effect. If the moisture is not removed from the gases, water vapor and crystals will form and freeze the compressor.

Does ozone layer has cooling effect?
Ozone does have a cooling effect. It is because of its properties.
The effort of relative humidity and how temperature affects the body?
Evaporation of moisture has a cooling effect and our bodies use the effect to control internal temperatures. The ability of of an atmosphere to absorb moisture is determined by the amount of moisture it has already absorbed. For instance, at room temperature (21 degrees C) air at 101 kPa pressure can hold 18.3 grams of moisture per cubic metre of air. If the air contains only 12 grams of moisture then it contains about 65% of the total amount it could contain. Therefore it's relative humidity is 65% and it has the ability to absorb more moisture. Obviously, as the relative humidity of an atmosphere rises it's ability to absorb more moisture decreases thus suppressing evaporation and the cooling effect it produces for our bodies. In short, higher humidity causes us to feel hotter as we lose our ability to cool ourselves.
Drinking water placed in porous clay water pots to refrigerate water?
Water that penetrates through the pores of the clay vessel is evaporating; evapora-tion is a phenomenon with absorption of energy, so that it is a slight cooling effect on the water content of the pot.
What effect of moisture content on angle of repose of chalk?
An increase in moisture content typically results in a decrease in the angle of repose of chalk. This is because moisture lubricates the particles, reducing friction between them and causing them to slide more easily past each other. As a result, the chalk particles are less able to stack compactly, leading to a lower angle of repose.
What is the moisture content in boards?
determine the feasibility of commercial, off-the-shelf, and potentially low-cost ultra-wideband radio hardware to serve as a measurement tool for the moisture content of building materials. The study examined both reflections from and transmission through an envelope assembly when pulses with a center frequency of 4.7 GHz were emitted towards the materials. The reflected energy was found to be the best measure of moisture content. Tests on oriented strand board, plywood, and gypsum board showed that a linear trend was found between the reflected energy and moisture content of the two wood products, but the range of moisture contents in the gypsum boards was insufficient to have any appreciable effect on the signal returned. The ability to independently measure the moisture content of several layers with a single scan was also examined, but the data suggest that more work is needed to accomplish this goal.Building and Fire Research LaboratoryNational Institute of Standards and TechnologyGaithersburg, MD 20899Ref: http://www.fire.nist.gov/bfrlpubs/build06/PDF/b06020.pdf
