TEOREMA DE TORRICELLI
Doy muchos puntos,abajo viene la respuesta,quiero saber el procedimiento,

Answer 1

1) Datos:

P1 = 3000 N/m²

P2 = 4500 N/m²

V1 = 4 m/s

d = 1000 kg/m³

1/2 = 0.5

---------------------

P1 + 1/2 × d × V1² = P2 + 1/2×d×V2²

P1 + 1/2×d×V1² - P2 = 1/2×d×V2²

V² = P1 + 1/2d×V1² - P2 /1/2×d

$v2 = \sqrt{ \frac{2(p1 +0.5 \times d \times v1 {}^{2} - p2) }{d} }$

$v2 = \sqrt{ \frac{2(3000 + 0.5 \times 1000 \times 4 {}^{2} - 4500 ) }{1000} }$

V2 = 3.6 m/s

2)

Datos:

P1 = 300 pa

P2 = 18000 pa

h2 = 10.5 m

h1 = ????

-------------------

P1 + dgh1 = P2 + dgh2

dgh1 = P2 + dgh2 - P1

h1 = P2 + dgh2 - P1 / dg

h1 = 18000 + 1000×9.8×10.5 - 300/1000×9.8

h1 = 12.3 m

3)

Datos:

D = 2 cm

h = 5 m

V = ??

Q = ???

$v = \sqrt{2gh}$

$v = \sqrt{2 \times 9.8 \times 5}$

V = 9.89 m/s

Q = V×A

Q = V×3.1416×r²

Q = 9.89 m/s × 3.1416×(0.01 m)²

Q = 0.0031 m³/s
