i don't know because i thought flow rate was constant. no i can't show more effort, I've been staring at this problem for two hours now, googling, and flipping through my textbook and i still have a blank sheet of paper. As i stated, i don't know anything about linear transport so i don't know...

So I have NO IDEA how to do this problem. I am assuming it has to do with linear transport because that's the next section in the book but we have yet to talk about this in lab and briefly (one slide) discussed this in lecture. I tried reading in my book which was did no good as it just showed...

and I don't see how to manipulate A1V1=A2V2 to fit into this whole equation

I already did all of that^^ and I have what the change in velocity is. And that's where I am stuck. I don't know how to turn the velocity difference of 144 m/s into V1

omg can someone pleaaaaaaaaaaaase help me. 4 hours later and I still can't finish the problem

I figured out the next calculation, here's what i have so far Δp+ ρgh=0---> Δp= -ρgh----> Δp= - {13,600 kg/m3* 9.8m/s2 * -.1m)----> Δp= 13,328 pascals and ΔP= -1/2ρΔV2---> 2ΔP/ρ= -ΔV2----> 2 * 13,328kg/ms2/1.28kg/m3= -ΔV2-----> 26656kg/ms2/1.28kg/m3=-ΔV2-------> 20825m2/s2= -ΔV2 this is where...

1. Air at 0∘C flows through the tube shown in the figure. Assume that air is an ideal fluid. What is the air speed v1 at point 1?2. Formulas: A1V1=A2V2, ΔP + 1/2ρΔV2, ρgΔh3. My first through process was to calculate the change in pressure in the mercury as the change in pressure in the...
