Gas distribution from a nozzle and a series of nozzles has been studied. The simple axisymmetric, round, free jet and multijet and two dimensional, free jet and multijet were investigated by employing a set up with one nozzle, three and five nozzle series and measured by using a pitot tube. The results show that the variation in the centreline mean velocity decay (decay rate) of the one circular nozzle, three and five circular nozzle series follows inverse law decay, x-1 whereas the variation in the centreline mean velocity decay (decay rate) of the one rectangular nozzle, three and five rectangular nozzle series follows an inverse square root law decay, X-1/2 The mean velocity profiles in the centre plane, z = 0, for circular and rectangular type of the one nozzle and the three and five nozzle series show a continuous broadening of the velocity of the jet in the different downstream stations and across the submerged jet.
