Answer:
Explanation:
Units...Nothing is accurate without UNITS. 8.0±0.3 lbs,? Newtons? 3.5±0.2 m²? ft²? cm²? km²? furlong²? fathoms²?
your answer will be 8.0±0.3 / 3.5±0.2 units / units²
14) 3 because there is nothing stopping the wind, and it has a fatser speed than the bottom one.
15) Is 3 again, I am not completely sure, but since it is being eroded it should be smaller and smoother than before.
16) 1 because that is a true fact, I believe Alfred Wenger came up with the theory of continental drift because of this.
17) 2 because it is the top layer.
Answer:
a. V = 0.015 m³
b. ζ = 195.58 kg acetone / hr
Explanation:
a.
Assume ideal gas behavior can use the equation
n₁ = 1.1 bar / 1.013 bar = 1.085 * 1m³( 273 k / 478 k ) * ( 1 kmol / 274 m³)
n₁ = 0.0276 kmol
Pacetone = 0.1 bar ⇒ y₁ = 0.1 bar / 1.1 bar
y₁ = 0.09090
Pacetone = 0.379 bar ⇒ y₃ = 0.379 bar / 40 bar
y₃ = 9.475 x10 ⁻³
n₁ * y₁ = n₃ * y₃ ⇒ 0.0276 * ( 1 - 0.09090) = n₃ * ( 1 - 9.475 x 10⁻³)
n₃ = 0.0253 kmol
n₁ = n₂ + n₃ ⇒ n₂ = 0.0276 - 0.0253 = 2.30 x 10 ⁻³ kmol
Volume condesed
V = 0.0253 kmol * 22.4 m³ * ( 283 / 273 ) * ( 1013 bar / 40 bar )
V = 0.015 m³
b.
To calculate the rate vaporized
ζ = 20.0 m³ / hr *( 0.0276 / 0.014 kg * m³ ) *( 0.09090 kmol a / kmol ) * ( 5808 kg a / kmol a )
ζ = 195.58 kg acetone / hr
