Direction: At a station, Storm I of 5 hour duration with intensity 2 cm/h resulted in a runoff of 4 cm and Storm II of 8 hour duration resulted in a runoff of 8.4 cm. Assume that the φ-index is the same for both the storms.
-
The φ-index (in cm/h) is
-
- 1.2
- 1.0
- 1.6
- 1.4
Correct Option: A
| φ-index = | ||
| 5 |
| = | = | = 1.2 cm/hr | ||
| 5 | 5 |
