Question: 1 ) A 4 cylinder engine runs at 3 6 0 0 rpm with a compression ratio of 5 using the following cycle: State

1) A 4 cylinder engine runs at 3600 rpm with a compression ratio of 5 using the following cycle:
State \(1\rightarrow \) State 2: Air at 100 kPa and 300 K is compressed isothermally from a volume of 1 L down to its minimum volume. The initial entropy is \(5.706[\mathrm{kj}/\mathrm{kg}-\mathrm{k}]\)(Not isentropic)
State \(\mathbf{2}\rightarrow \) State 3: The air is instantaneously heated to 700 K
State \(3\rightarrow \) State 4: The air is expanded isothermally back up to the bottom dead center (Not isentropic)
State \(\mathbf{4}\rightarrow \) State 1: The air is cooled instantaneously back down to 300 K
We are now stepping up the HW assignment quality. The standard is that someone not in the class could read your work and understand it. Solve this question by hand. Use \( c_{v}=0.7\mathrm{~kJ}/\mathrm{kg}-\mathrm{K}\),\( R=0.3\mathrm{~kJ}/\mathrm{kg}-\mathrm{K}\), and \( k=1.4\)
a)(3 points) Draw the system, find the mass in the system, as well as the minimum volume \(\mathrm{dsa}(\) top dead center), and the maximum volume (bottom dead center).
b)(10 points) Sketch solution of one cycle in a P-V ("Big" volume) and a T-s for guidance and identify the processes.
c)(18 points) For each state show your control volume, and list all the state variables. (\(\mathrm{P}_{1}\mathrm{~T}_{1}\)\( s_{1} u_{1} V_{1}\))(Hint: "Big" V, not specific volume). And for each process show your energy equation, and list what stays constant between each state and its following state. (ie: what stays constant between \(1\rightarrow 2,2\rightarrow 3\ldots \))
d) Work and Heat
i)(2 points) Find the isentropic work, and specific work from State 1 to 2
ii)(2 points) Find the total and specific heat input from State 2 to 3
iii)(2 points) Find the isentropic work, and specific work from State 3 to 4
iv)(2 points) Find the total and specific heat output from State 4 to 1
v)(2 points) Find the net work using the isothermal work out and work in to the system, and thermal efficiency (Hint: use the isothermal work equation)
e)(2 points) Using the net work you found in the previous question, what is the power output of the engine, in KW? What is the mean effective pressure (MEP)?
