The Bernoulli equation for steady frictionless incompressible flow along a streamline between two locations 1 and 2 can be written as Water flows without friction from the top of a tank of water open to the atmosphere along a streamline from location 1 to 2, where it discharges into the atmosphere. Atmosphere With the datum for elevation as shown, the Bernoulli equation reduces to
Which one of the following is not an assumption of Bernoulli equation? -The flow is steady -No elevation change -The flow is incompressible -There is no friction -There is no shaft work

Question 1 The Universal Flow Principle applies to all systems that involve the flow of mass or energy.t is surprising that most of the equations relating to flow can be re-arranged into the form qedF/R (where q-the flow rate of mass or energy, ΔFis the driving force and R is the resistance to the flow). In a lot of cases, the resistance is also a function of the driving force itself, as you will see below. Using the Universal Flow...
