![]() Medicine looks at heat exchange in the human body to develop clothing, wetsuits and sleeping bags. The thermal properties of soil indicate the absorption and evaporation of water and the energy stored in the soil. In agricultural or weather study, soil heat flux is an important parameter. From there, you can determine the thermal resistance or transmittance value of the material.Īs energy efficiency becomes more critical, measurements of heat gain and loss through walls, windows, and the entire building envelope are tested and measured. Thermal sensors measure loss or gain through the component of a building envelope. It does not store any personal data.Engineers and architects often apply heat flux calculations to their work.

The result is then divided by four times pi multiplied by the squared radius in feet.Įv (lx) = фv (lm) / A (m) 2, where the illuminance in lux is calculated by dividing the luminous flux in lumens by the surface area in square meters.Įv (lx) = фv (lm) / (4.∏.r 2(m) 2), which means that the illuminance in lux is computed by dividing the luminous flux in lumens by four times pi multiplied by the squared sphere radius in meters. It means that the illuminance in lux is calculated by multiplying 10.76391 by the luminous flux in lumens. It means that the illuminance in lux is calculated by multiplying the luminous flux in lumens by 10.76391 and the result divided by the surface area in square feet.Įv (lx) = 10.76391 x фv (lm) / (4.∏.r (ft) 2). This calculator uses a particular formula in executing the conversionsįormula of calculating lumens to lux FeetĮv (lx) = 10.76391 x фv (lm) / A (ft2). Enter 15 in the spherical radius text field before you click the ‘Calculate’ button. If the luminous flux in lumens is 1500 (lm) and with a spherical radius of 15 feet, determine the illuminance result in lux.įirst, you will enter 1500 in the initial text field of the luminous flux in lumens and select the unit type as area in square feet. Confirm that you have entered the appropriate values in the required text field before you click the ‘Calculate’ button. ![]() Proceed to the next field where you enter the spherical radius in feet or surface area in squared feet. It can either be in square feet or square meters. The initial step is to enter the luminous flux in lumens and then select the unit type of the area. It has three text fields and two controls that perform different functions of the calculator. It is a conversion calculator that is used to convert the luminous flux in lumens (lm) to the illuminance in lux (lx). ![]() What is a Blog and Why Do You Need One to Make Money Online from Your blog. ![]()
