HM 150.01 Pipe Friction Apparatus
Education / GUNT Hamburg / Fluid Mechanics and Hydrology / Fundamentals of Fluid Mechanics /


 The experimental set-up can be used on its own or with the HM 150 Basic Hydraulics Bench. A supply of water is all that is required for operation. The unit is suitable for measuring pipe friction losses for laminar and turbulent flows. The experimental set-up is clearly laid out on a training panel. For investigations on laminar flow, a head tank is used for the water supply, whilst for turbulent flow, the supply is provided via the Basic Hydraulics Bench directly (or the water mains). The water flows through a pipe section, the flow is adjusted using reducing valves. The connection to the required measuring device is made via pressure tappings.
