C. Assuming a fixed-priority scheduling. Consider two tasks to be executed periodically on a single processor, where task 1 has

period p= 4 and task 2 has period p= 6.
If execution time of task I be e;=1
Find the maximum value for the execution time e2 of task 2 such that the Rate Monotonic (RM) schedule is feasible. ​

Air enters a compressor operating at steady state at 1.05 bar, 300 K, with a volumetric flow rate of 21 m3/min and exits at 12 b
omeli [17]

Answer:

- 46.5171kW

Explanation:

FIrst, the value given:

P1 = 1.05 bar (Initial pressure)

P2 = 12 bar (final pressure)

Heat transfer, Q = - 3.5 kW (It is negative because the compressor losses heat to the surroundings)

Mgaseous nitrogen = Mair = 28.0134 Kg/mol (constant)

Universal gas constant, Ru = 8.3143 Kj/Kgmolk

Specific gas constant, R = 0.28699 Kj/KgK

Initial temperature, T1 = 300 K

Final temperature, T2 = 400 K

Finding the volume:

P1V1 = RT1

V1 = RT1 ÷ P1

= (0.28699 Kj/KgK X 300k) ÷ 105

Note convert bar to Kj/Nm by multiply it by 100

V1 =  0.81997 m3/Kg

To get the mass flow rate:

m = volumetric flow rate / V1

= (21 m3/min x 1/60seconds) ÷ 0.81997 m3/Kg

= 0.4268Kg/s

Using tables for the enthalpy,

hT1 = 300.19 KJ/Kg

hT2 = 400.98 KJ/Kg

The enthalpy change = hT2 - hT1

= 100.79 KJ/Kg

Power, P = Q - (m X enthalpy change)

= - 3.5 - (0.4268 X 100.79)

= - 46.5171kW

Consider the following chain-reaction mechanism for the high-temperatureformation of nitric oxide, i.e., the Zeldovich mechanism
vagabundo [1.1K]

Answer: hello attached below is the properly written chain reaction  to your question

answer :

d[NO] / dt = k_{1f} [O] [N_{2}] + K_{2f}  [N][O_{2} ] + K_{3f}[N][OH]

d[N] / dt = k_{1f} [O] [N_{2}] + K_{2f}  [N][O_{2} ] - K_{3f}[N][OH]

Explanation:

<u>write out expressions for  d[NO] / dt and d[N] / dt</u>

Given :

properly written chain reaction ( attached below)

Expression for d[NO] / dt can be written as

k_{1f} [O] [N_{2}] + K_{2f}  [N][O_{2} ] + K_{3f}[N][OH]

Expression for d[N] / dt can be written as

k_{1f} [O] [N_{2}] + K_{2f}  [N][O_{2} ] - K_{3f}[N][OH]
