The effect of the increasing gas velocity on the pressure drop in the fixed beds with a length of 35.10-3, 45.10-3, 55.10-3, 65.10-3 and 75.10-3m which were generated in the downflow reactor has been established by experimental method. Ergan and Darcy-Weisbach equations have been used as the numerical methods to calculate the pressure drops within the Reynolds number range of 312 £ Re £ 1177. The difference between experimental and calculated values of pressure drops was found to be increased with the increase of the Reynolds number. Maximal relative error between experimental and theoretical values does not exceed ± 3%.
