Abstract
The ability of flow discharge is very necessary in pipeline. When changes in discharge flow in the pipe, the flow pattern and water level will be different. The design of test equipment used is a pipe network made of acrylic pipes with inner diameter (d1) 64 mm and (d2) 44 mm. The fluid used is standard water with a viscosity value of 1.14 cp, fat oil 0 mg/L, and specific gravity 1.0304 gr/cm3. Data collection on the testing pipeline is divided into 10 segments or 10 observation points (OP) per discharge. Variations of debits flowed are 0.5 liters/sec, 1.2 liters/sec, 3.5 liters/sec. The relationship between discharge and depth of flow or water level from the bottom of pipe and the relationship between discharge and flow velocity is directly proportional or linear. The greater of discharge value flowed resulted in a shift in the flow characteristics where the low discharge value, the laminar flow patterns and transitions and high discharge values of flow pattern becomes turbulent.
