As part of its commitment to sustainability, a company is looking for a way to track the source of purchased goods and how they

pentagon [3]

The primary technology that would enable the company to achieve this goal of tracking its purchased goods and their production is the Blockchain.

The blockchain technology is a type of computer technology that helps to secure a system. This technology is duplicable and distributed over all of the networks that are affiliated to the blockchain.

Due to this characteristic that it has, the company would be able to fulfill its goal of tracking the source of this good.

A seasonal color change helps animals in the Taiga to

Len [333]

Answer:

Evade predators

Explanation:

The taiga forest biome which is located in the subartic region bounded by the tundra and the temperate forests in the North and South respectively, extends across the continents of North America, Europe and Asia forms the most enormous land ecosystem of related plants and animals on Earth

In the taiga, the colors of the furs of some animals change with the season such that they are become obscured to potential predators in the taiga

Animals that are able to have a camouflage that enables them to evade predators include

1) Ermine changes color from dark brown coat in the summer to white in the winter

2) Crossbill changes color from orange-brown in the summer to white in the winter

3) Snowshoe Hare changes color from brown in the summer to white in the winter.

Carbon dioxide gas enters a pipe at 3 MPa and 500 K at a rate of 2 kg/s. CO2 is cooled at constant pressure as it flows in the p

Viktor [21]

Answer:

a) 0.0629 $m^{3}/s$ ,ρ1=31.76 $kg/m^{3}$ ,0.05688 $m^{3}/s$

b) 0.06171 $m^{3}/s$ ,32.40966 $kg/m^{3}$ 0.05498 $m^{3}/s$

c) 0.004%

given data:

n=2 kg/s

R=188.92 J/kgK

$T_{1}$ =500 K

$T_{2}$ =450 K

solution:

a) as we know ideal gas relation

PV=nRT..........(1)

The volume flow rate of inlet is

$V_{1}= \frac{nRT_{1} }{P}$ ..................(2)

putting the value in eq(2)

$V_{1}$ =0.0629 $m^{3}/s$

to find destiny

ρ1= $\frac{n}{V_{1} }$ ...........................................(3)

putting value of n and V1 is eq 3

ρ1=31.76 $kg/m^{3}$

$V_{2} =\frac{nRT_{2} }{P}$ ............(A)

putting value in eq A

=0.05688 $m^{3}/s$

to find the rates from the compressibility factors we have to find the reduced pressure and temperature in both cases

P(reduced 1)= $\frac{P_{1} }{P_{crit} }$ = $\frac{3.10^{6} }{7.39 . 10^{6}}$ =0.41

T(reduced 1)= $\frac{T_{1} }{T_{crit} }$ = $\frac{500K}{304.25K}=1.64$

b) After looking at the chart we obtain $Z_{1}$ =0.98 now the volume flow rate at the inlet is:

$V_{1} =\frac{nRT_{1} Z_{1} }{P}$ ....................................................(4)

Putting the values in eq(4)

=0.06171 $m^{3}/s$

Now the density is

ρ= $\frac{n}{V_{1} }$

=32.40966 $kg/m^{3}$

now the reduced pressure and compressibility factor in second case will be

T(reduced 2)= $\frac{T_{2} }{T_{crit} }$ = $\frac{450}{304.25}$ =1.48

P(reduced 2)=P(reduced 1)=0.41

$Z_{2}$ =0.97

$V_{2} =\frac{nRT_{2} Z_{2} }{P}$ ............................................(5)

putting value in eq (5)

=0.05498 $m^{3}/s$

c) now find the error

Δn/n=modulus(ρ1 $V_{1}$ -n/n)*100%.....................(6)

putting the value in eq 6

=0.004%
