1.	Which of the following terms is modified in the integrated energy balance equation for non-uniform velocity distribution?(a) Potential energy(b) Kinetic energy(c) Pressure energy(d) Thermal energyThe question was asked in an interview for job.I want to ask this question from Effects of Friction and Velocity Distribution topic in section Pouring – Gating Design, Melting Furnaces, Melting and Casting Quality of Casting-Forming-Welding I
Answer» RIGHT answer is (b) Kinetic energy Easiest explanation: The non-uniform velocity DISTRIBUTION can be accounted for by modifying the kinetic energy term in the integrated energy balance equation by replacing the (velocity)² term by v̅²/β, where v̅ is the AVERAGE velocity and β is a constant. β is equal to 0.5 for laminar flow and 1 for turbulent flow in a circular conduit.
