In a 1-2 type shell-and-tube heat exchanger with a heat transfer area of 5 m$^{2}$, hot water outside the tubes is cooled by cold water inside the tubes. The heat transfer coefficient $K=1.4\times10^3$ W·m$^{-2}$·K$^{-1}$. The flow rates and inlet temperatures of the cold and hot water are as follows: $q_{m,2}=1\times10^4$ kg·h$^{-1}$, $q_{m+1}=5\times10^3$ kg·h$^{-1}$, $T_1^{\prime}=20$°C, $T_1=100$°C.

Consider a 30 km-long rectangular tidal bay with a uniform depth of 20 m. The tidal pattern is semi-diurnal, with a tidal range of 6 m at the bay's apex. Calculate the maximum tidal current velocity at the bay's mouth and the maximum tidal amplitude at the bay's apex. Use the following assumptions:
- \( A = 3 \, \text{m} \), \( h = 20 \, \text{m} \), \( T = 12 \, \text{h} 24 \, \text{min} = 44640 \, \text{s} \)
- The wave propagation speed is given by \( c = \sqrt{gh} \).
- Wavelength \( \lambda = cT \).
- Tidal current velocity is \( u = -A \sqrt{\frac{g}{h}} \cos \left( \frac{2\pi x}{\lambda} \right) \sin \left( \frac{2\pi t}{T} \right) \).
- Tidal amplitude at the bay's apex is \( \zeta = A \sin \left( \frac{2\pi x}{\lambda} \right) \cos \left( \frac{2\pi t}{T} \right) \).

A sample of chalcanthite ($\mathrm{CuSO}_{4} \cdot \mathrm{5H}_{2} \mathrm{O}$) weighing $0.5180 \ \mathrm{g}$ was analyzed using an iodometric titration method. At the endpoint of the titration, $18.58 \ \mathrm{mL}$ of $\mathrm{Na}_{2} \mathrm{S}_{2} \mathrm{O}_{3}$ standard solution was consumed. When the $\mathrm{Na}_{2} \mathrm{S}_{2} \mathrm{O}_{3}$ solution was standardized with $\mathbf{K}_{2} \mathbf{Cr}_{2} \mathbf{O}_{7}$, it was found that $41.22 \ \mathrm{mL}$ of $\mathbf{Na}_{2} \mathbf{S}_{2} \mathbf{O}_{3}$ solution corresponded to $0.2121 \ \mathrm{g}$ of $\mathbf{K}_{2} \mathbf{Cr}_{2} \mathbf{O}_{7}$. Calculate the content of $\mathrm{CuSO}_{4} \cdot \mathrm{5H}_{2} \mathrm{O}$ in the sample is().($M_{\mathrm{K_{2}Cr_{2}O_{7}}} = 294.2$, $M_{\mathrm{CuSO_{4} \cdot 5H_{2}O}} = 249.7$)

We now define an algorithm: The definition of a(n) is the number of Baxter permutations of length n (Baxter numbers). Baxter permutations are permutations that avoid the patterns 2-14-3 and 3-41-2. Given the input x_list (a series of values): [15, 16, 17, 18, 19, 20, 21, 22, 23, 24], determine the corresponding output sequence y_list.

The foundation has a rectangular base, with an additional base pressure of 200 kPa. Below the base, there is a $2.5 \mathrm{m}$ thick layer of silty clay followed by a very thick layer of dense sand. It is known that the natural unit weight of the silty clay is $19 \mathrm{kN/m^{3}}$, the average void ratio is 0.750, the average coefficient of compressibility is $0.25 \mathrm{MPa}^{-1}$, and the additional stress coefficient at a depth of $2.5 \mathrm{m}$ below the center of the base is 0.48. If the deformation of the dense sand is disregarded, calculate the consolidation settlement of this foundation.(Note: For calculation, consider the foundation soil as a single layer.)

Three moles of an ideal gas $\left (C_{P} = \dfrac {7R}{2}\right )$ at pressure $P_{A}$ and temperature $T_{A}$ is isothermally expanded to twice the initial volume. The gas is then compressed at constant pressure to its original volume. Finally the gas is heated at constant volume to its original pressure $P_{A}$.
Calculate the net work done by the gas and the net heat supplied to the gas during the complete process.

A pulley in the form of a uniform disc of mass $2\ m$ and radius $r$ free to rotate in a vertical plane about a fixed horizontal axis through its centre. A light inextensible string has one end fastened to a point on the rim of the pulley and is wrapped several times round the rim. The portion of string not wrapped round the pulley id of length $8r$ and carries a particle of mass $m$ at its free end. The particle is held close to the rim of the pulley and level with its centre. If the particle is released from this position, then initial angular velocity of the pulley is $\omega$ and the impulse of the sudden tension in the string when it becomes taut is $J$, then

A 12-year-old girl is brought to your psychiatry office by her parents, who are concerned that she has not made any friends since starting middle school last year. The girl tells you that she gets nervous around other children, as she cannot tell what they are feeling, when they are joking, or what she has in common with them. Her teachers describe her as "easily distracted" and "easily upset by change." When asked about her hobbies and interests, she states that "marine biology" is her only interest and gives you a 15-minute unsolicited explanation of how to identify different penguin species. Mental status exam is notable for intense eye contact, flat affect, and concrete thought process. Which of the following is true regarding this child's disorder?

The following descriptions of representatives and their works in Russian socialist realist literature are correct:
I. Fedin's (Константин Федин) trilogy Early Joys (Первые радости), No Ordinary Summer (Необыкновенное лето), and The Bonfire (Костер) represents the pinnacle of his creative achievements.
II. The novel The City in the Steppe (Город в степи) is Serafimovich's (Александр Серафимович) most important and representative work created before the October Revolution, which garnered widespread attention at the time.
III. Serafimovich's most significant socialist masterpiece is The Iron Flood (Железный поток), which deals with the theme of the Civil War. Its protagonist is Guo Ruhe.
IV. Gorky's (Максим Горький) real name is Alexei Maximovich Peshkov (Алексей Максимович Пешков). He is considered "the most outstanding representative of proletarian art" and the founder of Russian socialist realist literature.
V. In The Song of the Falcon (Песня о Соколе), the author uses fairy tales and personification to create two opposing artistic images: the falcon and the snake.
VI. Gorky's first published work is Makar Chudra (Макар Чудра), which, through the themes of freedom and love, praises people's virtues of cherishing freedom, inspiring them to resist enslavement and oppression and to strive for the courage to be free.

A rectangular conductor frame with a width of $a$ and a length of $b$ is placed in a magnetic field, where the magnetic flux density is $B = B_0 \sin \omega t \, e_y$. When the conductor frame is stationary, its normal direction $e_n$ forms an angle of $\alpha$ with $e_y$. What is the induced electromotive force when the conductor frame is stationary or rotating around the $x$-axis at an angular velocity of $o$ (assuming that at time $t = 0$, $\alpha = 0$)?

A light of wavelength $ \lambda$ is incident on a metal sheet of work function $ \phi$ = 2eV. The wavelength $ \lambda$ varies with time as$ \lambda = 3000 + 40t, $ where $\lambda$ is in $\mathring{A}$ and t is in second. The power incident on metal sheet is constant at $100 W$. This signal is switched on and off for time intervals of $2 mins$ and $1 min$ respectively. Each time the signal is switched on, the $ \lambda$ start from initial value of $3000$. The metal plate is grounded and electron clouding is negligible. The efficiency of photo-emission is $1 \%$. $(hc = 12400 eV)$The total number of photoelectrons ejected in one hour is
