Bernoulli's Equation for Nonviscous Flow Can Be Stated as $\rho$ = 14 G/cm³,and Viscosity Is Neglected,the Difference Between Pressure P₂ at a Fluid

question 41

Multiple Choice

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 A₁= 0.75 cm² to A₂ = 0.030 cm². When v₁ = 3.5 cm/s, $\rho$ = 1.4 g/cm³,and viscosity is neglected,the difference between pressure P₂ at A₂ and P₁ at A₁ is

• A)54 \(\times\) 10³ dyn/cm²,with P₁ higher.
• B)59 dyn/cm²,with P₂ higher.
• C)59 dyn/cm²,with P₁ higher.
• D)8.3 \(\times\) 10² dyn/cm²,with P₂ higher.
• E)None of these is correct.
