Answer:
a) 358.8 KJ/kg
b) 0.0977 KJ/K- kg
c) 83.28%
Explanation:
N2 at 300 k. ( use the properties of N2 at 300 k (T1) )
Cp = 1.04 KJ/kg-k , Cv = 0.743 KJ/Kgk , R = 0.1297 KJ/kgk , y = 1.4 ,
Given data:
T2 = 645 k
P1 = 1 bar , P2 = 10.5 bar
<u>a)Determine the work input in KJ/Kg of N2 flowing </u>
Winput = h2 - h1 = Cp( T2 - T1 ) = 1.04 ( 645 - 300 ) = 358.8 KJ/kg
<u>b) Determine the rate of entropy in KJ/K- kg of N2 flowing </u>
Rate of entropy ( Δs ) = Cp*InT2/T1 - R*In P2/P1
= 1.04 * In (645/300) - 0.1297 * In ( 10.5 / 1 )
= 0.0977 KJ/K- kg
<u>c) Determine isentropic compressor efficiency </u>
Isentropic compressor efficiency = 83.28%
calculated using the relation below
( h'2 - h1 ) / ( h2 - h1 ) = ( T'2 - T1 ) / ( T2 - T1 )
where T'2 = 587.314
Answer:
they are important together, but if you want to use just one future you must think about which one is first needed. and then try to learn for economical so don't use more money
<em>Logs.</em>
<em>Like data logs. Sometimes people make these logs to keep tabs on other people or to get important information put down somewhere that way it is saved and can be looked back upon later. Anytime someone makes an action on the computer, it makes a TMP file representing a log of what you want it to do before the computer quickly get's rid of the file.</em>

Answer:
0xEA44
Step by Step Explanation:
To find addition in Hex system, let's explain the meaning of characters A to F in Hex systems. A represents 10, B represents 11 ... F represents 15. So,
(E1A3)₁₆ + (8A1)₁₆
E1A3
08A1
Adding from most right side to left ->
- 3+1=4
- A+A=10+10=20. If we find its remainder i.e. dividing by 16, 4 will be the remainder and 1 will be the whole number i.e. 20=16*<u>1</u>+<u>4</u> this 4 will be written at second place on right side while 1 will be carried out to the left side.
- <u>1</u>+1+8=10=A
- E+0=14=E
So the number becomes:
<em><u>EA44</u></em>
