Experimental Investigation of Laminar Flow of Lubricant Oil Through a Transparent Tube.

Abstract

Fluid is a substance that flows no matter how little the stresses. It has both laminar and turbulent pattern depending on flowing fluid. Reynolds formula is a means of distinguishing the type of flow depending on the flow Reynolds number, Re < 2000 (laminar flow), Re >4000 (turbulence flow) and Re between 2000 and 4000 gives a critical region. It has several applications both in science and engineering field. This paper investigates some important works done on numerical analysis and modeling of laminar flow in pipe. This review is focused on some methods of approach and the analytic tools used in analyzing of the important parameters to be considered in laminar flow such as viscosity, velocity, flow rate, density of fluid and pipe shape. This work was done considering a given form of pipe configuration or shape which is circular pipe & no friction.
