PRESSURE LOSSES FROM FRICTION AND LOCAL RESISTANCE FOR TURBULENT FLOW REGIME IN PE PIPES Ф16/2

Roumen Gadjev

Abstract


This paper presents the results obtained from laboratory experiments for total pressure losses in turbulent flow regime with drip irrigation smooth pipes PE16/2, 12,7 mm in diameter. Relationships for determination the sum of friction and local pressure losses in drip laterals with diffferently spaced local resistance (drippers) are presented. The relationship for determination of total coefficient of resistance and head losses obtained from the experimental and analytical studies is shown as well.

Keywords


pressure flows, flow regimes, pressure losses, flow coefficient of resistance.
