Bernoulli's Equation for Nonviscous Flow Can Be Stated as P₁ $\rho$

question 13

Multiple Choice

Bernoulli's equation for nonviscous flow can be stated as p₁ + $\rho$ gy₁ + $\rho$ v₁² = p₂ + $\rho$ gy₂ + $\rho$ 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, $\rho$ = 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.
