Answer:

\dot m = 2.74 kg/s

Explanation:

given data:

pressure 1 MPa

diameter of pipe  =  30 cm

average velocity = 10 m/s

area of pipe= \frac[\pi}{4}d^2

                 = \frac{\pi}{4} 0.3^2

A = 0.070 m2

WE KNOW THAT mass flow rate is given as

\dot m = \rho A v

for pressure 1 MPa, the density of steam is = 4.068 kg/m3

therefore we have

\dot m = 4.068 * 0.070* 10

\dot m = 2.74 kg/s

Consider a pan of water being heated (a) by placing it on an electric range and (b) by placing a heating element in the water. W
Brrunno [24]

Answer:

Method B is the more efficient way of heating the water.

Explanation:

Method B is more efficient because by placing a heating element in the water as in described in method B, the heat that is lost to the surroundings is minimized which implies that more heat is supplied directly to the water. Therefore, more heating is achieved with a lesser amount of electrical energy input. Whereas placing the pan on a range means more heat losses to the surrounding and as such it will take a longer time for the water to heat up and also take more electrical energy.

Explain why many sustainable fishing and forestry practice depend on the actions of consumers like you.
ehidna [41]

Answer:

The reason why many sustainable fishing and forestry practice depend on the actions of consumers like me is:

  • <u>The offer is aimed at satisfying the demand for these products</u>.

Explanation:

Sustainable fishing and  forestry are based on allowing future generations to access the same products that we currently have, for this reason, a sustainable fishing practice can be waiting for fish to reproduce, in order to not to overexploit them and thus to extinguish them, however, as mentioned in the answer, the offer is aimed at satisfying the demand, therefore, <u>if consumers like me demand sea products even though they are not in the breeding season or without providing the time for the ecosystem to recover the extracted products, the supply will be forced to supply the demand despite the extinction of a species; The same applies to sustainable forestry, if they carry out reforestation work on wood products in proportions 10-1 (10 plants planted for each tree cut) or higher, but the consumer does not provide the prudent time to obtain wood products again, the indiscriminate felling in order to supply the product required by the consumer</u>.

shtirl [24]

Electronic returnless fuel systems use an  in-line fuel supply pump.

<h3>What is the role of electronic Returnless fuel systems?</h3>

Electronic returnless EFI systems is known to bean “On Demand” returnless EFI systems due to the fact that it make use of fuel tank pressure sensor to examine fuel pressure.

Therefore, one can say that an Electronic returnless fuel systems use an  in-line fuel supply pump.
