Water is flowing through a channel having a length of 5 cm breadth of 4 CN. Density of water can be taken as 1000 kg/ m^2 and viscosity of water is 10^-3 pa-s. Velocity with which water is flowing is 2.5m/s. Calculate the following A) hydraulic diameter B) Reynolds number C) predicts if flow is laminar or turbulent along with reason for your conclusion D) for fluid flowing in a pipe with diameter of 5 CN and having Reynolds no 2300 , calculate the hydraulic entry length.
