Our power plant generates electricity using a steam turbine. At the exit from our power generation process, we end up with 562.0

Answer:

The mass flowrate of the cooling water needed to meet the regulation is 560 kg/s

Explanation:

The given information are;

The mass flow rate of the water = 562.0 kg/s

The temperature of the exit water = 330.0 K

The allowable temperature of the of released water into nearby river = 310.00 K

The temperature of the cool water with which the temperature of the exit water is cooled = 290.00 K

Therefore, we have;

Heat gained by the mixture = The heat of the final mixture exited to the river

Q = m×c×ΔT

$m_w$ = 562.0 kg/s

The mass of the cooling water = x

The final temperature = 310 K

4.2×562×(330 - 310) = x×4.2×(310 - 290)

47208 = 84×x

x = 47208/84 = 560 kg

Therefore, the mass flowrate of the cooling water needed to meet the regulation = 560 kg/s.

A color that is almost gray has a ________ saturation.

Mama L [17]

When we see a solid color that is red, blue, or black let's say, it is said to have a high saturation of color. A color that is almost gray has very little or very saturation. Of course, the amount of gray can vary greatly but for the most part a color that is almost gray has little or no saturation at all.

Hey guys, I have a question about heat and stuff, and converting. THINK YOU COULD HELP?! THANKS!

Alexxandr [17]

Before answering this question it is necessary to know the conversion factors for temperatures.

273 k = 0 ° C

To transform a temperature from Kelvin to ° C we use the following Formula

T ° C = T Kelvin - 273

For 373 K

373K -273 = 100 ° C

373 Kelvin equals 100° C.

To transform a temperature from ° C to ° F we use the following formula:

(T° C x 9/5) + 32 = T ° F

Then:

For 0 ° C

(0° C x 9/5) +32 = 32 ° F

0° C equals 32 ° F.

For 100° C

(100 ° C x 9/5) +32 = 212 F

100 ° C equals 212 ° F.

Therefore, the correct option is the first:

373 Kelvin = 100 ° C = 212 ° F

Two charged particles are placed 2.0 meters apart. The first charge is +2.0 E-6 C, and the second charge is +4.0 E-6 C. What is

Anestetic [448]

The electrical force between the two charges can be calculated as +1.8×10⁻² N and its repulsive.

To find the electrical force, distance = 2 meters

charge q1 = 2×10⁻⁶ C

charge q2 = 4×10⁻⁶ C

<h3>Define coulomb's law and solve with formula.</h3>

The force of attraction or repulsion acting along a straight line between two electric charges is directly proportional to the product of the charges and inversely to the square of the distance between them.

Formula can be written as,

F = K ( q1q2 / r² )

F - electric force

k - Coulomb constant

q1, q2 - charges

r - distance of separation

Substituting the values in the formula,

F = 9 × 10⁹ Nm²/C² ( (2×10⁻⁶ C × 4×10⁻⁶ C) / (2²))

= 0.0179751

F = 1.8 × 10 ⁻² N.

As both the charges q1 and q2 are positive, the charges gets repulsive.

SO, the correct answer is Option A.
