Experimental Study on Muddy Water Delivery for Irrigation in Low-Pressure Pipeline System


Article Preview

Abstract. Non-depositing critical velocity is an important parameter in project design for low pressure pipeline irrigation system. By using indoor experimental system of water pipeline conveyance, the non-depositing critical velocity with different sediment content has been researched. The results show that the non-depositing critical velocity increases with the increasing of sediment content, but it does not increase substantially with the increasing of sediment content. The empirical formula of non-depositing critical velocity has been drawn, and close agreement between the empirical formula and the measured data exists with a correlation coefficient R2=0.95, which can provide the basic theoretic reference to prevent pipe from being clogged in channel irrigation area.
