A canal was designed to supply the irrigaiton needs of 1200 hectares to land growing rice of 140 days base period having a Delta of 134 cms. If this canala water is used to irrigate wheat of base period 120 days having a Delta of 52 cm, the area (in Hectares) that can be irrigated is
-
- 2650
- 3608
- 543
- none of the above
Correct Option: A
| Discharge, Q = | ||
| D |
| D = 8.64 × | ||
| Δ |
| ∴ Q = | ||
| 8.64 × B |
For rice and wheat discharge is same.
Qrice = Qwheat
| = | |||
| 8.64BR | 8.64BW |
| = | |||
| 140 | 120 |
∴ AW = 2650 hectares
