Conservation of rain water and reducing soil erosion is the central theme for developing areas on watershed basis. In general, resource conservation measures are long range benefit programmes and immediate returns are rarely spectacular. Since investable resources are scarce and therefore, need judicious...
Typical heat pump COPs are about 3.0 for air-source heat pumps and in the 3.0-6.0 range for geothermal heat pumps. Even so, the heat pump COP will depend on the inside and outside temperatures. How do I calculate the coefficient of performance for a refrigerator? We can calculate a refri...

Coefficient of Variation (in financial terms) is also referred to as volatility of the investment. Naturally, the investment having a lower degree of volatility is the safer one. Thus, in the investment scenario, the formula of the coefficient of variation should be,CV...
1.On what factors does the coefficient of friction depend? In physics, the friction coefficient is the force acting between two objects divided by the force pushing them together. Coefficients of friction range from zero to one. They can be divided into two types: ...
New formulas are presented for the reflection coefficient at the open end of a rectangular waveguide radiating into air including the effect of wall thickness or flange. Existing formulas require significant amount of numerical calculations and do not cover the practical range of waveguide dimensions. ...

Particle size was measured by Microtrac S3500 laser particle size analyzer produced by Microtrac Inc., U.S. The range of the particle size of the analyzer is 0.02–2000 μm and that of the detection angle is 0.02–160°. The analyzer can eliminate the interference of refraction and reflected...
There are a few ways tocalculate correlation in Excel. The simplest way is to input two data series in adjacent columns and use the built-in correlation formula: Investopedia.com If you want to create a correlation matrix across a range of data sets, Excel has a data analysis plugin. To ...
coefficient of correlation,correlation coefficient,correlation- a statistic representing how closely two variables co-vary; it can vary from -1 (perfect negative correlation) through 0 (no correlation) to +1 (perfect positive correlation); "what is the correlation between those two variables?" ...
