The conditions at the beginning of compression in an Otto engine operating on hot-air standard with k=1.35 and 101.325 kPa, 0.05

Katyanochek1 [597]

Answer:

$P_m=181.42 KPa$

Explanation:

$P_1=101.325 KPa,V_1=0.05m^3,T_1=32C$ ,K=1.35

Clearance is 8%.

Heat added=15 KJ

We know that compression ratio $r=1+\dfrac{1}{C}$

$r=1+\dfrac{1}{0.08}$

r=13.5

$r=\dfrac{V_1}{V_2}$

$13.5=\dfrac{0.05}{V_2}$

$V_2=3.7\times 10^{-3}$

We know that efficiency of otto cycle

$\eta =1-\dfrac{1}{r^{k-1}}$

$\eta =1-\dfrac{1}{13.5^{1.35-1}}$

$\eta =0.56$

$\eta =\dfrac{W}{Q}$

W is the work out put and Q is the heat addition.

$0.56 =\dfrac{W}{15}$

W=8.4 KJ

We know that Work =Mean effective pressure x swept volume.

Here swept volume $V_s=V_1-V_2$

$V_s=0.05-3.7\times 10^{-3}$

$V_s=0.0463 m^3$

Noe by putting the values

Work =Mean effective pressure x swept volume.

$8.4=P_m\times 0.0463$

$P_m=181.42 KPa$

Describe two components of the MEDC mechanized agricultural system that may lead to an increase in water stress

Zina [86]

Mechanized agriculture refers to agricultural machinery capable of facilitating and enhancing agriculture. Mechanized agriculture does not require moving the soils and therefore is hard for water to enter into it.

<h3>What is mechanized agriculture?</h3>

Mechanized agriculture refers to the use of different technologies (e.g., precision agriculture GPs) in order to increase farmworker productivity.

Mechanized agriculture is a common practice in developed countries (MEDCs), whereas this practice is relatively uncommon in developing countries (LEDCs).

The techniques of mechanized agriculture do not require moving the soils and therefore is hard for water to enter into it.

Compare automation and autonomous

denis-greek [22]

Answer:

Automation generally means “a process performed without human assistance”, while autonomy implies “satisfactory performance under significant uncertainties in the environment and the ability to compensate for system failures without external intervention [emphasis mine].”
