Homework Statement A horizontal water main with a cross-sectional area of 184 cm2 necks down to a pipe of area 45.0 cm2. Meters mounted in the flow on each side of the transition coupling show a change in gauge pressure of 70.0 kPa. Determine the flow rate through the system, taking the fluid...

I got it! That was right! Thank-you so much for all of your help. You were so helpful, thorough, and you really made me think! Thank-you again! Is there any way to rate people on the site because I would really like to give you an amazing rating! :)

Well, thank-you! That makes me feel a little better! ok so...I think #1 should still increase. Would #3 actually increase because if you divide by a smaller length, the frequency would be larger?

I am fairly certain that #2, #4, and #5 are right. So would either #1 and #3 be wrong? I'm not really sure even by looking at the equations. I'm sorry! I thought I was understanding better...

I think I am missing something because I put that in my answer, and it said it was wrong... :(

ok great! So, 1.) increase 2.)stays the same 3.)decrease 4.)stays the same 5.)increase Is this correct? Thanks again for helping!

When I combine equations 2 and 3, it looks to me like an increase in the tension will cause an increase in the fundamental frequency... ok, sounds good! I will check back later too. Thank-you again!

Would the speed stay the same because the frequency is what depends on the length?

Since A is not related to any equations involving f, decreasing it would not make a difference to the fundamental frequency, so the f would stay the same, even if L is increased? and v would decrease with an increase in the length?

I honestly am not sure about #2. Do the amplitude and the fundamental frequency have any relation? For #4, would I look at equation 2 and make it v=f*2L? PS: Thank-you for your help and patience. I am slowly understanding. :)

Would it increase because the L is bigger? Then for #3, it would decrease?

Would one be stays the same because the fundamental frequency is constant? Is v/f=2L the expression?

would that mean 1,2,3,5 would have the answer stay the same? I'm still not sure...

okay, I think I see. The second harmonic is one full wavelength, and the first (fundamental) is half of a wavelength.

oh ok, Sorry! Does L equal the wavelength?
