Un aljibe de 12.4 m de profundidad se encuentra totalmente lleno de agua. ¿Cual es la presión en el fundo debido únicamente al p
Kamila [148]

Answer:

a) p = 121644 Pa

b) p_{T} = 221644 Pa  

Step-by-step explanation:

a) La presión en el fondo debido únicamente al peso del agua se puede calcular usando la siguiente ecuación:

p = \rho gh

En donde:

ρ: es la densidad del agua = 1000 kg/m³

g: es la gravedad = 9.81 m/s²

h: es la profundidad = 12.4 m

p = \rho gh = 1000 kg/m^{3}*9.81 m/s^{2}*12.4 m = 121644 Pa

Entonces, la presión en el fondo debido al agua es 121644 Pa.

b) Para hallar la presión total en el fondo debemos ahora considerar la presión atmosférica:

p_{T} = p_{0} + \rho gh  

En donde p₀ es la presión atomsférica = 75 cmHg

p_{T} = 750 mmHg\frac{1 Pa}{0.0075 mmHg} + 121644 Pa = 221644 Pa

Por lo tanto, la presión total en el fondo es 221644 Pa.

I = 308 x .06 x 1

I = $18.48

You will pay $18.48 interest for one year.
