Abstract: A simple apparatus for measuring the efficiency of sub-nozzle has been developed by checking the air velocity at the nozzle outlet at the predetermined pressure. The testing set-up can also be used for the comparison of different types of nozzles, either main or sub-nozzles. It is observed that sub-nozzle with 19 holes gives less air velocity than that of one circular hole sub-nozzle. This is because of the possible contamination due to which the holes of used sub-nozzles get blocked and remain not so smooth, thus giving less air velocity, and hence the lower efficiency. Based on the above, continuous measuring of sub-nozzle efficiency has become a necessity. The design of the suggested apparatus is simple and reliable.
