Answer:

13.) 44V

14.) 66V

15.) 9A

16.) 12V

Explanation:

Concepts you need to know:

1. Resistors in series can be combined by summing up their values.

2. The current always stays the same when the resistors are in series.

3. Ohms Law:   V = IR

13.) We know that the resistors are in series so we can combine them into a single big resistor. We got R₄ = R₃+R₂+R₁ = 2+4+5 = 11Ω.

We also know that current is the same in a series of resistors, so there's 4A going through the entire circuit.

Using ohm's law, we can calculate V = IR = (4)(11) = 44V

14.) Same explanation as part (13). Except now the current is I=6A. All we have to do is to replace the previous I=4 to I=6.

V = IR = (6)(11) = 66V

15.) Again, we know that current is the same when resistors are in series. So if you can find the current through R1 then that's the same current throughout the entire circuit.

We're given E₁=18V, so...

I = V/R = E₁/R₁ = 18/2 = 9A

this means 9A will also flow through R₃.

16.) Same concept as part (15). We know that E₃=15V, so lets find the current.

I = V/R = E₃/R₃ = 15/5 = 3A

Since current is same throughout the circuit, I₁=3A as well. Use this to calculate the voltage through R₁.

V = IR = I₁R₁ = (3)(2) = 6V

Obtaining data from property tables

State 1:

\left.\begin{array}{l}P_{1}=1.25 \text { bar } \\\text { Sat - vapour }\end{array}\right\} \begin{array}{l}h_{1}=234.45 \mathrm{kJ} / \mathrm{kg} \\S_{1}=0.9346 \mathrm{kJ} / \mathrm{kgk}\end{array}

State 2:

\left.\begin{array}{l}P_{2}=5 \text { bor } \\S_{2}=S_{1}\end{array}\right\} \quad h_{2}=262.78 \mathrm{kJ} / \mathrm{kg}

State 3:

\left.\begin{array}{l}P_{3}=5 \text { bar } \\\text { Sat }-4 q\end{array}\right\} h_{3}=71-33 \mathrm{kJ} / \mathrm{kg}

State 4:

Throttling process  h_{4}=h_{3}=71.33 \mathrm{kJ} / \mathrm{kg}

(a)

Magnitude of compressor power input

\dot{w}_{c}=\dot{m}\left(h_{2}-h_{1}\right)=\left(8 \cdot 5 \frac{\mathrm{kg}}{\min } \times \frac{1 \mathrm{min}}{\csc }\right)(262.78-234 \cdot 45)\frac{kj}{kg}

w_{c}=4 \cdot 013 \mathrm{kw}

(b)

Refrigerator capacity

Q_{i n}=\dot{m}\left(h_{1}-h_{4}\right)=\left(\frac{g \cdot s}{60} k_{0} / s\right) \times(234 \cdot 45-71 \cdot 33) \frac{k J}{k_{8}}

Q_{i n}=23 \cdot 108 \mathrm{kW}\\1 ton of retregiration =3.51 k \omega

\ Q_{in} =6 \cdot 583 \text { tons }

(c)

Cop:

\beta=\frac{\left(h_{1}-h_{4}\right)}{\left(h_{2}-h_{1}\right)}=\frac{Q_{i n}}{\omega_{c}}=\frac{23 \cdot 108}{4 \cdot 013}

\beta=5 \cdot 758

Travka [436]

MVC architecture is defined as the architectural design that is used by software engineers for programming languages.

<h3>What are the various models of MVC architecture?</h3>

The various types of MVC architecture include the following:

  • The controller: This model is used to control logic and acts as the coordinator between the View and the Model.

  • The view: It displays the information from the model to the user.

  • The model: It is used to implement the domain logic.
