What is wrong with this solution to the following problem? Problem: Evaluate $2x + 5y$ for $x = 3$ and $y = 1$. Solution: $2x + 5y = 2(1) + 5(3)$ $= 2 + 15$ $= 17$ Choose the correct answer below. A. There is nothing wrong. Either number can be substituted for x and y. B. The solution should have been left in the form $2x + 5y$. C. The solution does not follow the order of operations. D. The values for x and y are incorrectly substituted.

Recalling that the equation for Reynolds number is $Re = \frac{vDh\rho}{\mu}$, where $D_h = \frac{4A_c}{P}$, if water is flowing through a square pipe with height and width of 1 m (cross-sectional area = 1 m$^2$ and perimeter = 4 m) at a velocity of 10 m/s and temperature of 5 degrees C, what is the Reynolds number? Note that water has a density of 1000 kg/m$^3$ and dynamic viscosity, $\mu = 1.52 \times 10^{-3} \frac{kg}{ms}$ at 5 degrees C. Characterize this flow as laminar, transitional, or turbulent.

Problem 4 (MCQ): 1. One of the purposes for performing the short circuit test in a transformer is to estimate its: (a) Copper loss (b) Core loss (c) Insulation Resistance (d) Total loss 2. A three-phase Y - \(\triangle\) transformer bank is to handle 500 kVA and has a 34.5/11-kV voltage ratio. The rating of each single-phase transformer in the bank (high voltage, low voltage, apparent power, and turns ratio) will be: (a) 19.9 kV, 6.35 kV, 167 kVA, 2.50:1 (b) 34.5 kV, 6.35 kV, 167 kVA, 4.33:1 (c) 19.9 kV, 11.0 kV, 167 kVA, 1.44:1 (d) 34.5 kV, 11.0 kV, 167 kVA, 2.50:1 3. Consider ideal transformer models only. The load voltage is phase-shifted from the supply voltage. The transformer is likely to be: (a) A step-up autotransformer (b) A step-down autotransformer (c) A three-phase Y-Y transformer (d) A three-phase Y-\(\triangle\) transformer 4. For a self-excited DC shunt generator, if no residual magnetism is present, the generator will (a) Be inefficient (b) Be highly efficient (c) Be dangerous to operate (d) Not start 5. Increasing the field resistance of a shunt DC generator will (a) Increase the induced voltage. (b) Decrease the induced voltage. (c) Not affect the induced voltage. (d) Make the induced voltage oscillate.

3. The probability of rain on any given day is dependent on the weather from the previous day. In fact, if it didn't rain yesterday, there is a 70% chance that it will not rain today. If it is as- sumed that there is a 40% chance of rain on any given day of the year, the probability that it will not rain for two consecutive days is a) 18% b) 42% c) 36% d) 28% 4. A bag contains 14 coins - 3 nickels, 5 dimes, and 6 quarters. If a nickel is taken out and not replaced, state the probability that the next coin drawn will be a dime. a) $\frac{5}{13}$ b) $\frac{5}{14}$ c) $\frac{6}{13}$ d) None of the above 5.
