Water Conveyance Efficiency Formula

Estimate the conveyance efficiency using table 7.

Water conveyance efficiency formula. It is obtained by the expression ηc wl wr 100 where ηc water conveyance efficiency wl amount of water applied to land wr amount of water supplied from reservoir. The gross depth of water per irrigation is obtained by dividing the net depth of water d net by efficiency as in equation 6. Water conveyance efficiency ec 100 v f v d 100 110 140 78 5. Where e a is application efficiency v s is volume of irrigation water stored in the crop root zone acre inch and v f is the volume of irrigation water delivered to the farm or field acre inch.

Ec water conveyance efficiency per cent wf water delivered to the farm by conveyance system at field supply channel wt water introduced into the conveyance system from the point of diversion water conveyance efficiency is generally low. It is the ratio of the amount of water applied to the land to the amount of water supplied from the reservoir. Equation 6 dgross dnet e example 4 based on the design parameters given in table 14 what are the net and gross depths. Determine the field application efficiency using table 8.

A water conveyance efficiency ηc. Water application efficiency it is a measure of efficiency of water application in the field. Water conveyance efficiency is the ratio of the volume of water delivered for irrigation to the volume of water placed in the conveyance system. Calculate the scheme irrigation efficiency using the formula.

Water application efficiency e a 100 v s v f. About 21 losses occur in earthen watercourses only. Assumed conveyance efficiency ec 0 90 1 farm irrigation efficiency ef eb x ea 0 45 0 60. Water application efficiency evaluates how well an irrigation system delivers water from the conveyance system to the crop and is calculated as.
