When calculating the amount of cooling (air conditioning) required in a room, you should take into account that the room should always be maintained at an ambient temperature of much less than 35 degree Celsius and that any other equipment in the room will also generate heat. Officially, Int...
How do I calculate weight loss in coffee roasting?First, weigh your batch before and after (it’s important not to miss a single bean when doing so!). Then, to covert weight loss to a percentage, use this formula: (Green Weight – Roasted Weight) / Green Weight * 100 = Weight Loss...
Windows.If your data facility has windows, you must calculate how much heat is generated by sunlight from all windows. A general calculation is 60 Btu/hour/ft2of window. ASHRAE considers location, hours of sunlight, building materials, window materials, refraction rates and more in their calcula...
The volume of a cylinder equals pi times the square of its radius times its height. To find the change in volume due to thermal expansion, calculate the dimensions before and after expansion, and apply the formula for volume to each case. Remember that radius is half of diameter. References...
One of the things that many of us are concerned about when considering raw veganism is hair loss because there are some people can actually start to lose their hair especially in the beginning of the lifestyle. There is some truth to this because when you adopt a fully raw vegan diet you...
We walk you through how to determine the heat loss for any room and where floor heating can help. Our radiant experts will highlight common heat loss sources as well as which products can help combat chilly rooms with radiant heating.
Furthermore, the mathematical models used to analyze design options have been modified to better calculate the impact of those design features on the cell heat balance and explore with more accuracy design options to further reduce the cell power consumption while maintaining a manageable cell ...
How much heat is required to raise the temperature of 475 grams of solid aluminum from room temperature (295k) to liquid aluminum at 1050K? Aluminum melts at 933.47k. How to calculate the energy change in the reaction N_2(g) + 3H_2(g) rightarrow 2NH_3(g)?...
To calculate the size of the power supply for your LED strip light, you need to calculate the total watts used in your strip. Each strip consumed a different amount of watts per ft (W/ft). Take the w/ft and multiply it by the number of total feet you are hooking up to the power...
In an unoccupied space, sounds can be heard from a variety of sources. Careful scrutiny of the room can lead to identifying the intrusive sources. The diagram illustrates a few of the most common sources of noise. Trust your senses – you’ve likely noticed that there are sources of noise...
