1. The problem statement, all variables and given/known data
River Pascal with a volume flow rate of 4.7×105 joins with River Archimedes, which carries 1.1×106 , to form the Bernoulli River. The Bernoulli River is 130 wide and 30 deep. What is the speed of the water in the Bernoulli River? 2. Relevant equations Express your answer using two significant figures. 3. The attempt at a solution I attempted to guesses so far. 0.120 m/s was wrong 1.20 m/s was wrong Thanks for all the help. Jared

Hi Jared! Welcome to PF!
(try using the X^{2} tag just above the Reply box )

For vfr=4.7*10^{5}L/s
I used the equation 4.7*10^{5}/3900 equals 1.2m/s Thanks for the help. Jared

Determing speed of water
Hi Jared!
(just got up …) The Bernoulli River contains the water of both River Pascal and River Archimedes.

@tinytim Did you come up with an answer of .40m/s where that incportates both rivers?
Thanks for your help, Jared

4.7*10^{5}L/s and 1.1*10^{6}L/s. 130m wide and 30m deep.
The answer needs to be expressed in m/s.
