Queremos un cilindro de simple efecto que utilice en su funcionamiento un volumen de aire a presión atmosférica de 13,122 litros
zhuklara [117]

Answer:

1) El diámetro es de aproximadamente 913,987 cm.

2) La fuerza del cilindro es 5576850 kgf

Explanation:

1) Los parámetros dados son;

El volumen del aire = 13,122 litros = 13122000 cm³

La presión de trabajo = 8.5 kgf / cm²

La longitud del cilindro = 20 cm.

Por lo tanto, tenemos;

El área de la base del cilindro = π · r² = 13122000 cm³ / (20 cm) = 656100 cm²

r = √ (656100 / π) ≈ 456,994 cm

El diámetro = 2 × r ≈ 2 × 456.994 ≈ 913.987 cm

El diámetro ≈ 913,987 cm

2) La fuerza del cilindro = El área de la base del cilindro × La presión de trabajo

∴ La fuerza del cilindro = 656100 cm² × 8.5 kgf / cm² = 5576850 kgf

La fuerza del cilindro = 5576850 kgf

At a distance 2.0 m from a localized sound source you measure the intensity level as 79 dB .How far away must you be for the per
jonny [76]

Answer:

6.32 m

Explanation:

Intensity of sound (I) is inversely proportional the distance to the source (d).

In decibels,

\Delta \beta=10log\frac{I_1}{I_2}=10 log\frac{d_2^2}{d_1^2}\\\\\Rightarrow 79-69=10 log\frac{d_2^2}{2^2}\\\Rightarrow 10 = 10 log\frac{d_2^2}{4}\\ \Rightarrow d_2^2=4\times 10\\\Rightarrow d_2=6.32 m
