The item that is least likely to cause an exhaust emission test failure as of a result of excessive nox emissions is; poorflow through the egr system.
<h3 /><h3>What is an exhaust emission?</h3>
Exhaust emissions simply means substances emitted into the atmosphere from the exhaust discharge nozzle of an aircraft or aircraft engine.
Now, when the test fails as a result of excessive nox emissions, we can say that high NOx emissions can occur when an engine's air-fuel mixture is too lean. Thus, we can conclude that the reason for exhaust emission test failure as of a result of excessive nox emissions is due to poorflow through the egr system.

Open system because there is mass (water) flowing through the system of interest (radiator)
Answer:
Refrigerant R-134a is to be cooled by waterin a condenser.The refrigerant enters thecondenser with a mass flow rate of 6 kg/minat 1 MPa and 70 C and exits at 35 C. The cool-ing water enters at 300 kPa and 15 C andleaves at 25 C. Neglecting pressure drops,determine a) the required mass flow rate ofthe cooling water, and b) the heat transferrate from the refrigerant to the water.SolutionFirst consider the condenser as the control volume. The process is steady,adiabatic and no work is done. Thus over any time intervalΔt,ΔEΔt=0and thusXin˙E=Xout˙Ewhere˙E=˙m h+12V2+gz650:351 Thermodynamics·Prof. Doyle Knight37

19-7 lol this is to easy im in middle school
Answer:
- The charge on the plates will increase with time
- The potential difference across the capacitor starts with zero and then increases gradually to a maximum value
- The current through the circuit starts high and then drops exponentially
Explanation:
<u>Case : An uncharged capacitor is connected to a resistor and a battery in a closed circuit.</u>
- The charge on the plates will increase with time
applying this equation : Q = as the value of (t) increases the value of Q increases i.e. charge on the plates
- The potential difference across the capacitor starts with zero and then increases gradually to a maximum value
applying this equation : V =
- The current through the circuit starts high and then drops exponentially
current : I =
