(might be called the field eqn.)<br />
Continuity Equation Example<br />
Example (<strong>FE</strong>IM):<br />
The speed of an incompressible fluid is 4 m/s entering the 260 mm pipe.<br />
The speed in the 130 mm pipe is most nearly<br />
(A) 1 m/s<br />
(B) 2 m/s<br />
(C) 4 m/s<br />
(D) 16 m/s<br />
A1v 1 = A2v 2<br />
A1 = 4A2 so v2 = 4v 1 = ( 4)<br />
4<br />
Therefore, (D) is correct.<br />
m ⎛ ⎞<br />
⎜ ⎟ = 16 m/s<br />
