To water his lawn, a homeowner uses two hoses. One connects to the faucet, the other to the end of the first hose to make the ho

se longer. Each hose is three meters long, but one has 20-mm diameter, the other has 40-mm diameter. When he turns on the faucet, the flow of water at the open end of the second hose measures 10 liters/min. How do the drops in pressure from the start to the end of each hose?

2)Encourage the viable use of raw resources and natural materials. Introduce strategies for continuously enlightening our environmental duty.

Introduce rules for continuous development in their ecological performance.

Obey with the law in force on conservational protection, and with other willingly recognized promises.

3)To encourage, by on-the-job practice, the participation of all our workers, independently and based on the team, in environmental safety problems.

4)To unite with the liable Agencies as well as Governmental Authorities.

To proceed with environmental protection courses.

5)To talk and report on our eco-friendly management struggles.

19 million Joules of chemical energy are supplied to a boiler in a power plant. 5 x 106 Joules of energy are lost through unburn
Fiesta28 [93]

Answer:

67.89%

Explanation:

Energy Efficiency=\frac {U_{energy}}{T_{energy}}\times 100

Where U_{energy} is useful energy and T_{energy} is the total energy

The useful energy= (19-5-1.1) million= 12.9 million

The total energy= 19 million

Efficiency=\frac {12.9}{19}\times 100=67.89473684\approx 67.89

Therefore, the efficiency of the boiler is 67.89%

(a) What is the distinction between hypoeutectoid and hypereutectoid steels? (b) In a hypoeutectoid steel, both eutectoid and pr
Gnoma [55]

Answer:

See explanation below

Explanation:

Hypo-eutectoid steel has less than 0,8% of C in its composition.

It is composed by pearlite and α-ferrite, whereas Hyper-eutectoid steel has between 0.8% and 2% of C, composed by pearlite and cementite.

Ferrite has a higher tensile strength than cementite but cementite is harder.

Considering that hypoeutectoid steel contains ferrite at grain boundaries and pearlite inside grains whereas hypereutectoid steel contains a higher amount of cementite, the following properties are obtainable:

Hypo-eutectoid steel has higher yield strength than Hyper-eutectoid steel

Hypo-eutectoid steel is more ductile than Hyper-eutectoid steel

Hyper-eutectoid steel is harder than Hyper-eutectoid steel

Hypo-eutectoid steel has more tensile strength than Hyper-eutectoid steel.

When making a knife or axe blade, I would choose Hyper-eutectoid steel alloy because

1. It is harder

2. It has low cost

3. It is lighter

When making a die to press powders or stamp a softer metals, I will choose hypo-eutectoid steel alloy because

1. It is ductile

2. It has high tensile strength

3. It is durable

An AM radio transmitter radiates 550 kW at a frequency of 740 kHz. How many photons per second does the emitter emit?
kifflom [539]

Answer:

1121.7 × 10³⁰ photons per second

Explanation:

Data provided in the question:

Power transmitted by the AM radio,P = 550 kW = 550 × 10³ W

Frequency of AM radio, f = 740 kHz = 740 × 10³ Hz

Now,

P = \frac{NE}{t}

here,

N is the number of photons

t is the time

E = energy = hf

h = plank's constant = 6.626 × 10⁻³⁴ m² kg / s

Thus,

P = \frac{NE}{t} = \frac{N\times(6.626\times10^{-34}\times740\times10^{3})}{1}          [t = 1 s for per second]

or

550 × 10³ = \frac{N\times(6.626\times10^{-34}\times740\times10^{3})}{1}

or

550 = N × 4903.24 × 10⁻³⁴

or

N = 0.11217 × 10³⁴ = 1121.7 × 10³⁰ photons per second
