Answer:
I think it is process or technology
Answer:
74,4 litros
Explanation:
Dado que
W = nRT ln (Vf / Vi)
W = 3000J
R = 8,314 JK-1mol-1
T = 58 + 273 = 331 K
Vf = desconocido
Vi = 25 L
W / nRT = ln (Vf / Vi)
W / nRT = 2.303 log (Vf / Vi)
W / nRT * 1 / 2.303 = log (Vf / Vi)
Vf / Vi = Antilog (W / nRT * 1 / 2.303)
Vf = Antilog (W / nRT * 1 / 2.303) * Vi
Vf = Antilog (3000/1 * 8,314 * 331 * 1 / 2,303) * 25
Vf = 74,4 litros
Answer:
Always make sure that you are properly protected and that it is all clear to be operated on.
Answer:
11548KJ/kg
10641KJ/kg
Explanation:
Stagnation enthalpy:
given:
cp = 1.0 KJ/kg-K
T1 = 25 C +273 = 298 K
V1 = 150 m/s
Answer: 11548 KJ/kg
Using Heat balance for steady-state system:
Qin = 42 MW
W = -100 KW
V2 = 400 m/s
Using the above equation
Answer: 10641 KJ/kg
c) We use cp because the work is done per constant pressure on the system.
Answer:
<em>Never</em>
Explanation:
In a reversible adiabatic process, there is not transfer of heat or matter between the system and its environment. An adiabatic reversible process is a process with constant entropy, i.e ΔQ=0. The internal energy is solely dependent on the work done either due to compression or expansion. So the entropy of the gas will never increase.
