The value of kinetic energy correction factor (a) for a laminar flow through a circular pipe, is

ANS:D - 2.5

The value of the kinetic energy correction factor (a) for laminar flow through a circular pipe is 2.02.0. This factor accounts for the correction in kinetic energy due to the non-uniform velocity distribution across the pipe's cross-section, which is more pronounced in laminar flow compared to turbulent flow. Therefore, the correct value of the kinetic energy correction factor (a) for laminar flow through a circular pipe is 2.02.0.
