A horizontal pipe of inner diameter 2.2 cm carries water with a density of 1000.0 kg/m3 flowing at a rate of 1.5 kg/s. If the pi

EleoNora [17]

The speed of the water in the wider part will be 1.194 m/sec. Speed is a time-based quantity. Its SI unit is m/sec.

<h3> What is speed?</h3>

Speed is defined as the rate of change of the distance or the height attained.

The given data in the problem is;

The initial diameter is, $\rm d_1 = 2.2 \ cm$

initial radius,

$r_1 = \frac{d_1}{2} \\\\ r_1 = \frac{2.2}{2} \\\\ r_1 = 1.1\ cm$

The initial crossection area;

$\rm A_1 = \pi r_1^2 \\\\ \rm A_1 = 3.14 \times (1.1\times 10^{-2})^2 \\\\ \rm A_1 =3.8 \times 10^{-4} \ m^2$

The final crossection area;

$\rm A_2 = \pi r_2^2 \\\\ \rm A_2 = 3.14 \times ( 2 \times 10^{-2})^2 \\\\ \rm A_2 = 12.56 \ m^2$

The initial flow rate is;

R = density ×velocity ×area

$\rm R = \rho A V \\\\ 1.5 = 1000 \times V_1 \times 3.8 \times 10^{-4} \\\\ V_1 = 3.947 \ m/sec$

The speed of the water in the wider part will be;

From the continuity equation;

$\rm A_1 V_1 = A_2V_2 \\\\\ 3.8 \times 10^{-4} \times 3.947 = 12.56 \times 10^{-4} \times V_2 \\\\ V_2= 1.194 \ m/sec$

Hence, the speed of the water in the wider part will be 1.194 m/sec.

Is there a way to see the color of cosmic rays the human eye can't see

KATRIN_1 [288]

You would have to use a machine to convert the colors to one visible by humans or become some other species of animal with a larger light spectrum.

if a mass on a spring bobs up nad down completing 2 full cycles every section. WHat are the periouds and frequency of the mass

Alika [10]

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of the time taken to complete one full cycle.

Frequency (f) will be calculated first as

f = N ÷ t

where N is the number of cycles and t is the time taken to complete one full cycle. The unit for frequency is Hertz (Hz).

To calculate the period, T, the formula below will be used

T = 1 ÷ f

The unit for period is secs

The Milky Way and Andromeda galaxies are members of the Local Group, a cluster of more than 50 galaxies spread across a spherica

fenix001 [56]

Answer:

2400 cm

Explanation:

The milky way has diameter of 100000 light years.

$100000\ ly=24\ cm\\\Rightarrow 1\ ly=\frac{24}{100000}\ cm$

The local group is the collection of galaxies which includes the milky way.

10 million light years is the diameter of the local group.

$10\times 10^6\ ly=10\times 10^6\times \frac{24}{100000}\ cm\\\Rightarrow 10\times 10^6\ ly=2400\ cm$

Hence, the diameter of the scale model of the local group would be 2400 cm
