The objective : 1. To determine the head loss and friction factor for laminar & turbulent flow in a smooth pipe over a range of Reynolds’s number . 2. To obtain the following relationships : a. Head loss as a function of the velocity of flow . b. Friction factor as a function of Reynolds number . Theory : The friction resistance to the flow of fluid through a pipe results in a loss of pressure energy for a given fluid flowing a long a given pipe‚ experiments show that for laminar flow
