Andrei [34K]

Answer:

B.197 gpm and 12.4 L/s

Explanation:

Given that

Load Q = 404.5 KW

Water inlet temperature= 6.1 °C

Water outlet temperature= 13.9°C

We know that specific heat for water

C_p=4.187\ \frac{KJ}{kg.K}

Now from energy balance

Q=\dot{m}C_p\Delta T

by putting the values

Q=\dot{m}C_p\Delta T

404.5=\dot{m}\times 4.187(13.9-6.1)

\dot{m}=12.38\ \frac{kg}{s}     (1 Kg/s = 15.85 gal/min)

We can say that

\dot{m}=196.31\ \frac{gal}{min}

We know that

\dot{m}=\rho\times volume\ flow\ rate

12.38=1000 x volume flow rate

volume\ flow\ rate\ = 12.38\times 10^{-3}\ \frac{m^3}{s}

So

volume flow rate = 12.38 L/s

So the option B is correct.

Mars2501 [29]

A material scientist investigates the characteristics of materials and their uses. Nature and human knowledge restrict the number of existing materials on Earth. This signifies that there is a limited amount of material available for use in the production of goods.

Given that they deal with the design and manufacturing of things, mechanical engineers sometimes lack the specialties seen in other branches of engineering. This necessitates a thorough understanding of all elements of engineering.

<h3>Why does Absolute Zero Exist?</h3>

Absolute zero, also known as zero kelvins, is equivalent to 273.15 degrees Celsius, or -459.67 degrees Fahrenheit, and represents the point on a thermometer where a system has the least amount of energy, or thermal motion. But there's a catch: absolute zero is unattainable, But exists as a measure of relativity.

Absolute zero is the temperature at which a thermodynamic system has the least amount of energy. It is equivalent to 273.15 degrees Celsius on the Celsius scale and 459.67 degrees Fahrenheit on the Fahrenheit scale.
