Galileo and heliocentric controversy

1 answer:

8 0

Many people believe that Galileo was hounded by the church for almost two decades, that he openly maintained a belief in heliocentrism, and that he was only spared torture and death because his powerful friends intervened on his behalf. But an examination of the fine details of Galileo’s conflict with church leaders doesn’t bear that out, according to English department distinguished research professor Henry Kelly.

Motor oil, with a viscosity of 0.25 N ∙ s/m2, is flowing through a tube that has a radius of 3.0 mm and is 1.0 m long. The drop

Alex73 [517]

Answer:

The average speed of the oil is 1 m/s.

Explanation:

Given that,

Viscosity $\eta= 0.25 N-s/m^2$

Radius r = 3.0 mm

Length = 1.0 m

Pressure = 200 kPa

We need to calculate the average speed of the oil

Using formula of pressure

$\Delta P=\dfrac{8\pi\eta\rho v}{A}$

$v=\dfrac{A\times\Delta P}{8\pi\eta\rho}$

Where, A = area

$\rho$ = density of oil

$\eta$ = viscosity

Put the value into the formula

$v=\dfrac{\pi\times(3.0\times10^{-3})^2\times200\times10^{3}}{8\pi\times0.25\times0.9}$

$v=1\ m/s$

Hence, The average speed of the oil is 1 m/s.
