Question
In the energy equation for flow in a pipe, a coefficient , appears in front of the term representing the velocity head. Concerning this coefficient, which of the following is true? a) should always be given a value of 1.0 if the flow is laminar; b) is needed to account for the kinetic energy lost due to friction in the viscous shear layers and velocity fluctuations related to turbulent flow; c) is needed to correct the kinetic energy since the velocity used in the calculation is the average velocity while in an actual pipe flow there is a distribution of velocities; d) is usually less than 1.0. e) C and d
the symbol that isnot shown well is alpha which is the coefficient
Explanation / Answer
kindly show the constants in the question properly. they are not readable
