By assuming steady-state, incompressible, inviscid, laminar flow in a horizontal pipe (no change in elevation) with negligible frictional losses, Bernoulli's equation reduces to an equation relating the conservation of energy between two points on the same streamline:

\Delta p = p_{in} - p_{out} =  \frac{1}{2} \rho v^2_{out} - \frac{1}{2} \rho v^2_{in} = \frac{1}{2} \rho v^2_{out} \cdot \left[ 1 - \frac{v^2_{in}}{v^2_{out}} \right]

The mass conservation (equivalent to continuity equation)
