This is an experimental device for measuring pressure loss and flow measurement techniques in various pipes and fittings, consisting of a main body and a measuring manometer. Using three types of pathways that include measuring instruments, straight pipes, and bent pipe components, the characteristics of each component are investigated and compared using a manometer and a differential pressure gauge. In addition to learning general measurement methods and the application of Bernoulli's theorem, the experiment will compare pressure losses in a Venturi tube and an orifice plate, as well as determine the pressure loss in a sudden expansion pipe. The Pitot tube system within the device will derive the velocity distribution and flow coefficient in the transparent pipe cross-section direction. The experiment requires a H1F hydraulic bench (sold separately) for water supply and flow measurement.
