PENGGUNAAN TEOREMA PI BUCKINGHAM PADA PENYELIDIKAN LOST HEAD UNTUK PIPA MENDATAR DENGAN ALIRAN TAK KOMPRESIBEL TURBULEN
Main Article Content
Abstract
Lost head can be interpreted as a decrease in the pressure
gradient and is a measure of resistance to flow through the pipe.
Barriers to flow through the pipeline will greatly affect the power
needed in moving the fluid so that the investigation of the lost
head on pipe important thing to do. Use of Buckingham Pi
theorem for dimensional analysis will make it easier to analyze
and make the move quicker and directed experiments. With the
initial data is a function of the barrier pipe diameter, fluid
viscosity, fluid density, pipe length, the fluid velocity and the
roughness of the pipe. The results indicate a lost connection head
per weight of the fluid (
w p /
) is proportional to the pipe
roughness factor (f) is proportional to the length of pipe per pipe
diameter (L / d) is proportional to the fluid velocity kuwadrat per
two times gravity (v
