MR-HL 102 Installation technology: losses in different pipes Vocational Training Equipment Thermal Lab Equipment
Description • pressure loss in pipes • different materials and diameters
When flow passes through pipes, pressure losses occur due to the frictionbetween the pipe wall and the water. The pressure loss is directly dependenton the surface roughness of the pipe inner wall, and thus on the material used. In addition, the pressure loss is affectedby the flow velocity and the cross-sectional area being flowed through. The MR-HL 102 unit makes it possible tostudy the pressure loss of incompressible fluids in fully flowed through straightpipe elements. The trainer is suitable forassessing how different materials andpipediameters affect the flow. The pipeelements used are commercially standard components in heating and sanitaryengineering. The clear panel is mountedon a sturdy, movable frame. Four straight pipe elements are mounted on the panel. These can be selectedindividually by ball valves. The flow is adjusted using valves in the inflow and return and read on a rotameter. The pressure measuring points in thepipe system are designed as annularchambers and are located between thebeginning and end of the measuring sections, ensuring a precise pressuremeasurement. The sensors are connected in pairs to a differential pressuremeter and the respective differentialpressure read on the display.
