Please explain how to set up and find answer. Thank you
To protect cities from flooding during heavy rains, open channels are sometimes constructed to handle runoff. The rate R at which water flows through the channel is modeled by R=k sqrt m, where m= slope of the channel and k is a constant determined by the shape of the channel.
a) suppose that a channel has a slope of m = 0.01 and a runoff rate of R=340 cubic feet per second. Find K.
b) If the slope of the channel increases to m=0.04 what happens to R?

I think that I just figured out a. 340=[\sqrt{0.01}\]

divide the sqrt on both side and I got 3400
