Question

Correct Bernoulli’s equation is (symbols have their usual meaning):

• A. \( P + mgh + \frac{1}{2} mv^2 = \text{constant} \)
• B. \( P + \rho gh + \frac{1}{2} \rho v^2 = \text{constant} \)
• C. \( P + \rho gh + \rho v^2 = \text{constant} \)
• D. \( P + \frac{1}{2} \rho gh + \frac{1}{2} \rho v^2 = \text{constant} \)

Hint:

Bernoulli’s theorem is fundamental for ideal fluid systems. Always ensure that terms represent energy per unit volume (pressure, potential energy, and kinetic energy) and use consistent units throughout.
