Water flows steadily through the variable area horizontal pipe shown in fig. p3.3. the centerline velocity is given by where x is in feet. viscous effects are neglected. (a) determine the pressure gradient, 1as a function of x2 needed to produce this flow. (b) if the pressure at section 112 is 50 psi, determine the pressure at 122 by 1i2 integration of the pressure gradient obtained in (a), 1ii2 application of the bernoulli equation. 0p0x, v 1011 x2 ˆi ft

step-by-step explanation:

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
