Cual es el impacto medioambiental del mortero?
ddd [48]

Explanation:

La industria del acero desecha gran cantidad de polvos, los que acopiados al aire libre, sobre el suelo y sometidos a ¡a acción de los agentes climáticos, contaminan el medio ambiente. El propósito del presente trabajo es evaluar el impacto ambiental que produce la incorporación de polvos de acería a matrices de cemento portland, sometidas a condiciones de humedad, presión y temperatura. Se caracterizó químicamente el material de desecho de una acería de Argentina, para identificar los elementos presentes. Por difractometría de rayos X (XRD) se determinaron las estructuras de las sustancias y su grado de oxidación. Se utilizó SEM-EDAX con el propósito de observar forma, tamaño y composición química de las partículas. Se elaboraron diferentes morteros de cemento Portland y se incorporó este material en diferentes porcentajes. Se moldearon probetas normalizadas para realizar ensayos mecánicos, de lixiviación y estudios petrográficos. Se analizó la composición química del agua de curado de las probetas y del líquido obtenido en ensayos de lixiviación. Los resultados permitieron identificar y cuantificar los elementos peligrosos que pueden se incorporados al ambiente y sugerir medidas de prevención.

An automobile tire with a volume of 0.8 m3 is inflated to a gage pressure of 200 kPa. Calculate the mass of air in the tire if t
saveliy_v [14]

Answer:

2.83 kg

Explanation:

Given:

Volume, V = 0.8 m³

gage pressure, P = 200 kPa

Absolute pressure = gage pressure + Atmospheric pressure

= 200 + 101 = 301 kPa = 301 × 10³ N/m²

Temperature, T = 23° C = 23 + 273 = 296 K

Now,

From the ideal gas equation

PV = mRT

Where,

m is the mass

R is the ideal gas constant = 287 J/Kg K. (for air)

thus,

301 × 10³ × 0.8 = m × 287 × 296

or

m = 2.83 kg
