Question 54

Multiple Choice

Bernoulli's equation for nonviscous flow can be stated as  Bernoulli's equation for nonviscous flow can be stated as   A fluid is flowing through a horizontal tube that changes in cross-sectional area from A<sub>1</sub>= 0.75 cm<sup>2</sup> to A<sub>2</sub> = 0.030 cm<sup>2</sup>.   When v<sub>1</sub> = 3.5 cm/s, \rho  = 1.4 g/cm<sup>3</sup>,and viscosity is neglected,the difference between pressure P<sub>2</sub> at A<sub>2</sub> and P<sub>1</sub> at A<sub>1</sub> is A) 54  \times  10<sup>3</sup> dyn/cm<sup>2</sup>,with P<sub>1</sub> higher. B) 59 dyn/cm<sup>2</sup>,with P<sub>2</sub> higher. C) 59 dyn/cm<sup>2</sup>,with P<sub>1</sub> higher. D) 8.3  \times  10<sup>2</sup> dyn/cm<sup>2</sup>,with P<sub>2</sub> higher. E) None of these is correct. A fluid is flowing through a horizontal tube that changes in cross-sectional area from A1= 0.75 cm2 to A2 = 0.030 cm2.
