A longitudinal profile of a river is shown in the figure below. If the average discharge of the river at reach AB is 200 m
3/s and increases to 300 m
3/s at reach CD, then the stream power from the reach AB to CD will change by a factor of _______. (Round off to two decimal places)
(Use g = 10 m/s
2, P
water = 1000 kg/m
3)
