Que presion manométrica debe de producir una bomba para subir agua del fondo del gran cañon ( elevación 730 m ) a indian gardens
Alexxandr [17]

Answer:

La presión manométrica debe ser 6,272,000 Pa = 61.9 atm

Step-by-step explanation:

La presión absoluta se refiere al valor de presión referido al cero absoluto o al vacío, sin presión atmosférica. Es decir, la presión absoluta es la presión con respecto al vacío total.

La presión manométrica es la que ejerce un medio distinto al de la presión atmosférica y representa la diferencia entre la presión real o absoluta y la presión atmosférica. Es decir, la presión manométrica se mide en relación a la presión atmosférica y se define como la diferencia entre presión absoluta (Pabs) y presión atmosférica predominante (Patm). La presión manométrica sólo se aplica cuando la presión es superior a la atmosférica.  

Entonces,  Pmanometrica = Pabs – Pamb

Para encontrar la presión a una profundidad h en un líquido sin movimiento, expuesto al aire cerca de la superficie de la Tierra, la presión manométrica puede ser calculada mediante:

Pmanometrica=ρ*g*Δh

donde ρ es la densidad del fluido, g la gravedad y Δh la variación en la altura.

En este caso:

  • ρ=1000 \frac{kg}{m^{3} } (densidad del agua)
  • g= 9.8  \frac{m}{s^{2} }
  • Δh=hfinal - hinitial= 1370 m - 730 m= 640 m

Reemplazando:

Pmanometrica=  1000 \frac{kg}{m^{3} } *9.8 \frac{m}{s^{2} } * 640 m

Resolviendo:

Pmanometrica= <u><em>6,272,000 Pa = 61.9 atm</em></u> (siendo 1 pascal = 9.869*10⁻⁶ atmósferas )

A rocket is launched from atop a 104-foot cliff with an initial velocity of 110 ft/s. A. Substitute the values into the vertical
miv72 [106K]

Answer:

7.68 s

Step-by-step explanation:

The vertical motion formula is:

h_{t} = h_{0} + v_{0}t - \frac{gt^{2}}{2}

<u>Where:</u>

h(t): is the final height = 0

h(0): is the height of the cliff = 104 foot

v(0): is the initial velocity = 110 ft/s

g: is the gravity = 9.8 m/s² = 32.15 ft/s²

Hence, from the vertical motion formula we can find the time that will take the rocket to hit the ground:

0 = 104 + 110*t - \frac{32.15t^{2}}{2}

0 = 104 + t(110 - 16.08t)

We have two solutions:

t₁= -0.84 s

t₂ = 7.68 s

We will take the positive value, thus the time that will take the rocket to hit the ground is 7.68 s.

I hope it helps you!
