Question

A lift irrigation scheme using a discharge of 96 $m^3/hr$ is planned to raise a crop with an average delta of 0.375 m. Intensity of irrigation is 60%. Assuming 3600 hours of working of the tubewell for a year, the culturable command area is

• A. 96 Ha
• B. 48 Ha
• C. 153 Ha
• D. 120 Ha

Answer 1

The correct option is C 153 Ha

By applying mass conservation,

$0.375\times 0.6\times A=3600\times 96$

$A=153600m^2(WhereA=Area)$

or

$A=153.6ha$
