88 p. The buoyant plume from a line source into a cross-section was studied, using the integral technique of analysis. Using similarity law, the jet trajectories and dilution ratio can be predicted and the required coefficients can also be found. The results of this investigation will enable further investigations to be made for· the design of waste disposal systems effluent into the ocean or' waste gases into the atmosphere. The present study based upon the assumption made by Fan and Shute. Numerical solutions were presented for a range of initial conditions. Experiments were conducted for the variation of the dilution ratio and for photographic observations of the trajectories of dyed jets. The problem of a buoyant jet from a line source into a cross-section was analyzed by assuming an entrainment mechanism based on the vector difference between the characteristic jet velocity and the ambient velocity. Experiments with sinking jet which are directly analogous to buoyant jet were performed. Salt solutions were injected into a fresh flowing water at the free surface in the flume. Jet trajectories and dilution ratios were obtained from titrating the samples. The coefficient of entrainment was found to vary from 0.04 to 0.24 and the drag coefficient was between 0. 9 to l. 2.
