Bernoulli's equation for nonviscous flow can be stated as p1 + gy1 + v12 = p2 + gy2 +
v22
A fluid is flowing through a horizontal tube that changes in cross-sectional area from
A1 = 0.75 cm2 to A2 = 0.030 cm2. When v1 = 3.5 cm/s, = 1.4 g/cm3, and viscosity is neglected, the difference between pressure p2 at A2 and p1 at A1 is
A) 54 *103 dyn/cm2, with P1 higher.
B) 59 dyn/cm2, with P2 higher.
C) 59 dyn/cm2, with P1 higher.
D) 8.3 * 102 dyn/cm2, with P2 higher.
E) 5.4 * 103 dyn/cm2, with P1 higher.
