ABSTRACT ABSTRACTThe present investigation evaluates the influence of three different step chute geometry when skimming flow was The present investigation evaluates the influence of three different step chute geometry when skimming flow was The present investigation evaluates the influence of three different step chute geometry when skimming flow was The present investigation evaluates the influence of three different step chute geometry when skimming flow was allowed over them with the allowed over them with the allowed over them with the allowed over them with the aim aim aim aim of determining the aerated flow length which is a significant factor when of determining the aerated flow length which is a significant factor when of determining the aerated flow length which is a significant factor when of determining the aerated flow length which is a significant factor when developing empirical equations for estimating aeration efficiency of flow. developing empirical equations for estimating aeration efficiency of flow. developing empirical equations for estimating aeration efficiency of flow. developing empirical equations for estimating aeration efficiency of flow. conducted in the Hydraulics Laboratory of the Department of Water Resource conducted in the Hydraulics Laboratory of the Department of Water Resource conducted in the Hydraulics Laboratory of the Department of Water Resource conducted in the Hydraulics Laboratory of the Department of Water Resource Ahmadu Bello University Zaria Ahmadu Bello University Zaria Ahmadu Bello University Zaria Ahmadu Bello University Zaria----Nigeria to determined the aeration efficiency of flow over the three different chute Nigeria to determined the aeration efficiency of flow over the three different chute Nigeria to determined the aeration efficiency of flow over the three different chute Nigeria to determined the aeration efficiency of flow over the three different chute geometry at the water temperature T and at the standard temperature of 20 geometry at the water temperature T and at the standard temperature of 20 geometry at the water temperature T and at the standard temperature of 20 geometry at the water temperature T and at the standard temperature of 20 were were were were analysed using analysed using analysed using analysed using a a a a regression model regression model regression model regression model efficiency of flow efficiency of flow efficiency of flow efficiency of flow for the three chute geometry under consideration. The results revealed that the aeration efficiency for the three chute geometry under consideration. The results revealed that the aeration efficiency for the three chute geometry under consideration. The results revealed that the aeration efficiency for the three chute geometry under consideration. The results revealed that the aeration efficiency increases with an increased in the increases with an increased in the increases with an increased in the increases with an increased in the length of aeration length of aera...
