| Abstract: | Calculated problem of frictional loss for the isothrmal flow of compressible fluid in slow variable area duct has been discussed. Replacing varing friction coefficient by average friction cofficient, calculating formula of friction loss has been obtained. Calculating results by use of this formula are in good a greement with results that have been obtained by the method of numerical calculation. |
