 P: 9 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

Show us your full calculations, and then we can see what went wrong, and we'll know to help!
 P: 9 For vfr=4.7*105L/s I used the equation 4.7*105/3900 equals 1.2m/s Thanks for the help. Jared

Hi Jared!

oh i see … you only used the volume flow rate of River Pascal.

The Bernoulli River contains the water of both River Pascal and River Archimedes.
 P: 9 @tiny-tim- Did you come up with an answer of .40m/s where that incportates both rivers? Thanks for your help, Jared

I go 4.0 times something

what are the units of the problem?
 P: 9 4.7*105L/s and 1.1*106L/s. 130m wide and 30m deep. The answer needs to be expressed in m/s.
