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
Answer:
Latin food is so diverse because the cuisine spans from all of the countries that Spain and Portugal conquered. We find these countries in South America.
Each of the Latin American countries in Hispanoamerica has its own unique flavors, styles and tastes. Their spices and and culture are different. Each country takes pride in the way they cook their meals and share them with family and others.
Explanation:
<span>When they say "peninsular Spanish" are referring to Spanish from Spain.
The definitions I found were not very clear as being specifically that type of Spanish, but I found this online translated as:
Bolazo
1. Violent blow with a bowl. (m)
2. (Cono Sur) silly remark, piece of nonsense (disparate); false news; fib, lie; mistake, error. (m)
Mandarse un bolazo -> to put one's foot in it</span>
