Answer:
Workdone, w = 68.935 kJ
Explanation:
m1h1 + m2h2 + Q = m3h3 - Wc
Final mass of mixture,
m3 = m1 + m2 = 5kg
p1V1 = m1R1T1
p2V2 = m2R2T2
Since they are at 1:1,
V1 = V2 and R1 = R2
Comparing equations,
p1/p2 = (m1/m2) x (T1/T2)
m1/m2 = (100/200) x ((50 + 273)/(25+273))
m1/m2 = 0.542
m1 = 0.542m2
m3 = m1 + m2
5 = m2 + 0.542m2
m2 = 3.243kg
m1 = 1.757 kg
Workdone is given as,
Wc = m3h3 - m1h1 - m2h2
h = Cp x T, since air is an ideal gas
Cp = 1.005kJ/kGK
Wc = (5 x 1.005 x (55+273)) - (1.757 x 1.005 x 298) -(3.243 x 1.005 x 323)
Wc = 68.935 kJ
Answer:
The three types of relearn procedures are auto relearn, stationary and OBD.
Explanation:
In TPMS system, after the direct service like adjustment of air pressure, tire rotation or replacement of sensors etc, is performed then maximum vehicle often needs TPMS system relearn that needs to be performed.
For performing these relearn procedure, there are mainly three types:
- auto relearn
- stationary relearn
- OBD
After applying the relearn process, the TPMS system will again be in proper function.
Answer:
Responsibility
Explanation:
By stamping the drawings that he was looking over, Jack Gillum conveys the fact that he is accepting responsibility for this work. The purpose of Gillum's stamp is to explain that such work has been under engineering review, and that it has fulfilled all the requirements that he watches our for. By putting his stamp in this work, Gillum accepts responsibility in case an error or a discrepancy is found in the drawings.
