DEVELOPMENT OF MATHEMATICAL MODEL ON PLUG FLOW APPLICATION INFLUENCED BY LINEAR PHASE VELOCITY IN HOMOGENEOUS SAND GRAVEL PORT HARCOURT METROPOLIS.

The behaviour of velocity in predominant sand gravel has been expressed; the concept of this study was to monitor the rate of fluids deposition in sand gravel formation, the velocity of flow experiences slight fluctuations in some deposited depths of the formations, while linear flow were found predominant, variation of velocity were observed base on the stratification as it is expressed on the lithology, the formation experiences low velocity in few simulated results, while predominant of linear velocity were observed in larger numbers of the study location, developed model generated theoretical values through simulation, these values were compared with experimental values, both parameters compared faviourably well, experts in soil and water engineering will definitely use this concept as a tool in design for various purpose.
