Architecture QUESTION #2343

Question 1326

Bernoulli's equation for steady incompressible flow expressed as energy per unit weight (head) along a streamline is:

$\dfrac{p}{\rho} + \dfrac{V^2}{2} + gz = C$
$\dfrac{p}{\gamma} + \dfrac{V^2}{2g} + z = C$✔️
$p + \dfrac{1}{2}\rho V + \gamma z = C$
$\dfrac{p}{\gamma} + \dfrac{V}{2g} + z = C$

Correct Answer Logic:

Bernoulli's equation in head form: $\dfrac{p}{\gamma} + \dfrac{V^2}{2g} + z = C$, summing pressure head, velocity head, and elevation head. Option A is the energy-per-unit-mass form (divided by $g$). Option C has incorrect units. Option D incorrectly uses $V$ instead of $V^2$ in the velocity head term.

Mechanical Engineering QUESTION #2425

Question 1332

For steady 1D conduction through a cylindrical wall (inner radius $r_1$, outer radius $r_2$, length $L$, conductivity $k$), the thermal resistance is:

$R_{cyl} = \frac{r_2 - r_1}{2\pi r L k}$
$R_{cyl} = \frac{\ln(r_2/r_1)}{2\pi L k}$✔️
$R_{cyl} = \frac{2\pi L k}{\ln(r_2/r_1)}$
$R_{cyl} = \frac{r_2^2 - r_1^2}{2kL}$

Correct Answer Logic:

For a hollow cylinder: $R_{cyl}=\ln(r_2/r_1)/(2\pi Lk)$. Temperature varies logarithmically, not linearly as in the plane wall.

Pharmacokinetics and Pharmacodynamics QUESTION #3829

Question 1336

A paediatric patient weighing $30$ kg is prescribed metronidazole $250$ mg every $8$ hours. Each mL of a $500\ \text{mg}/500\ \text{mL}$ ampoule contains $0.135\ \text{mmol/mL}$ sodium. What is the total sodium intake over $24$ hours?

$33.8$ mmol
$101.3$ mmol✔️
$202.5$ mmol
$1852$ mmol

Correct Answer Logic:

Three doses of $250$ mg each $= 3 \times 250\ \text{mL}$ of the solution. Volume per dose $= 250\ \text{mL}$, total $= 750\ \text{mL}$. Sodium $= 750 \times 0.135 = 101.3\ \text{mmol}$.

The Title 28 of the United States Code QUESTION #3711

Question 1338

A plaintiff sues a defendant for patent infringement. The court enters a final judgment in favor of the defendant. A year later, the plaintiff sues the same defendant for trade secret misappropriation based on the exact same set of facts and product development. The defendant moves to dismiss. What is the most likely result?

The motion is denied because the legal theories (patent vs trade secret) are different.
The motion is granted based on issue preclusion.
The motion is granted based on claim preclusion (res judicata).✔️
The motion is denied because the plaintiff did not 'actually litigate' the trade secret claim in the first case.

Correct Answer Logic:

Claim preclusion (res judicata) prevents a party from re-litigating a claim that was or *could have been* brought in a prior action between the same parties that resulted in a final judgment on the merits, provided the new claim arises from the same transaction or occurrence.
