According to Bernoullis principle, for an incompressible, non-viscous fluid flowing through a horizontal pipe, the total mechanical energy pressure energy kinetic energy potential energy per unit volume remains constant. In a horizontal pipe, potential energy remains constant, so the relation simplifies to Where P pressure fluid density v speed of fluid This implies an inverse relationship between pressure and speed If speed increases, pressure decreases If speed decreases, pressure increases Thus, the pressure is highest where the speed is lowest .
