You calculate the performance characteristics of the blade using either the Axial or Centrifugal calculation option the output data from which you use to calculate the performance of the fan. CalQlata has tried to simplify the subject with the fan calculator and its technical help page on this website. Most technical reference books and related data sites make this subject a little more complicated than it needs to be. and their performance is almost entirely governed by blade design and rotational speed, flow and head characteristics are generally governed by the fan's inlet and/or outlet ducts. What this program does: this program allows to calculate the pressure drop of each element present in the drying pipeline (valve, section change, elbow, etc…).Whilst most fan designs (axial, Sirocco, centrifugal, etc.) are suitable for many applications including extraction, distribution, compression, etc. See the GNU General Public License for more details.Ī copy of the GNU General Public License is available at In particular, this program is distributed “as is” without warranty regarding, but not limited to, any damages, loss of information, loss of profits, liabilities and/or injuries caused through the use of this program.

Please don't forget to add the pressure drop from the cyclone and the heat exchanger calculated in the other excel tools. Then, please enter the parameters of air flowrate :ĭepending of the design of your flash dryer, to calculate the pressure drop you have to select all the pipeline elements present on it.įor each element, you can calculate the pressure drop and then sum up all pressure drop. In a first part, please enter the following ambient conditions : To use this tool, please choose several input parameters located in colored cells with bold border on the “Main” tab.
