select the correct answer from the drop - down menu. the design for a two - tank system is shown. the inner tank must be surrounded by oxygen with a density of 0.0827 pounds per cubic foot. what amount of oxygen is needed in the outer tank? to meet the density required, approximately pounds of oxygen is required.

select the correct answer from the drop - down menu. the design for a two - tank system is shown. the inner tank must be surrounded by oxygen with a density of 0.0827 pounds per cubic foot. what amount of oxygen is needed in the outer tank? to meet the density required, approximately pounds of oxygen is required.

Answer

Explicación:

Paso 1: Calcular el volumen del tanque exterior

El volumen del tanque exterior es $V_{exterior}=20\times8\times6 = 960$ pies cúbicos.

Paso 2: Calcular el volumen del tanque interior

El volumen del tanque interior es $V_{interior}=5\times4\times3=60$ pies cúbicos.

Paso 3: Calcular el volumen del oxígeno

El volumen del oxígeno es $V = V_{exterior}-V_{interior}=960 - 60=900$ pies cúbicos.

Paso 4: Calcular la cantidad de oxígeno

Dado que la densidad del oxígeno es $0.0827$ libras por pie cúbico, la cantidad de oxígeno es $m=\rho V=0.0827\times900 = 74.43$ libras.

Respuesta:

74.43
