Answer:
Like you after singing in the recital
Answer:
So, basically, a Definite Article in spanish, is something you know, for example, "El chico" is "The boy", he is someone you know, and a Indefinite Article is something or someone you don't know, for example "Un Bolígrafo" is "A pen", it's not The Pen. Please, if you don't understand it let me know it. Thanks :).

If you have an iphome use the translator app and it works like a charm for these !
Realizamos un balance de energía
-Qs = m(h2 - h1) + m(V²/2 - V1²/2)
Con las presiones dadas nos dirigimos a la tablas de propiedades termodinámicas en vapor sobrecalentado
P1 = 800 kPa T = 400°C
h1 = 3267.7 kJ/kg
v1 = 0.38429 m³/kg
P2 = 200 kPa T = 300°C
h2 = 3072.1 kJ/kg
v2 = 1.31623 m³/kg
Calculamos el flujo masico,
m =dA1V = A1V/v1
m = 800cm²(1/100)²*10m/s / 0.38429 m³/kg
m = 2.05 kg/s
De la ecuacion de balance de energía
-25kW = 2.05kg/s(3072.1 kJ/kg - 3267.7 kJ/kg) + 2.05kg/s(V²/2 - (10m/s)²/2)
V2 = 606 m/s
Flujo volumetrico
Q = mv2
Q = 2.05kg/s * 1.31623 m³/kg
Q = 2.7 m³/s
