INTRODUCTION: The main goal of this experiment is to measure the static pressure variation in water flow along a converging-diverging channel and to compare it to estimate based on Bernoulli equation. The Bernoulli equation is an approximate relation between pressure velocity and elevation. Bernoulli equation focuses on the principle that a moving body gains potential energy as it is elevated to higher heights with the effect of gravity on this body of fluid producing potential energy. However Bernoulli equation can only be applied under certain conditions which includes inviscid, constant density, steady state flow and single stream lines. Bernoulli principle can be explained in terms of the law of conservation of energy. The higher the velocity of the fluid travelling, the more kinetic energy it had at the same time the work done by corresponding volumes in the wider and narrower pipes will be expressed by the product of the pressure and velocity. The Bernoulli's equation is given by: The equation can be used for compressible and incompressible flow. The use of this equation does not take into account turbulences, viscous losses and assumes the velocity profile follows the theoretical laminar flow. Laminar flow typically occurs during low speeds and there are two areas of turbulence. The channel flow ex
