The correct answers are A) determined from the amplitude recorded by a single seismometer. C) represents the amount of energy released. D) uses a logarithmic scale.
The news media often report an earthquake's magnitude on the Richter scale. The following items are characteristics of a Richter earthquake magnitude: determined from the amplitude recorded by a single seismometer, represents the amount of energy released, and uses a logarithmic scale.
When measuring the scale of the magnitude of earthquakes, the Richter scale measures the scale od moderated size earthquakes. It was invented by two United States seismologists: Charles F. Richer and Beno Gutenberg. They developed the measure in California when they were researching from 1927 through 1936, in the Seismological Laboratory of the Carnegie Institution of Washington, in Pasadena, California.
We can find the change in the enthalpy through the tables A5 for Saturated water, pressure table.
For 1bar=1000kPa:
Replacing,
With the specific volume we know can calculate the mass flow, that is
Then the heat required in input is,
With the same value required of 15000m^3/h, we can calculate the velocity of the water, that is given by,
Finally we can apply the steady flow energy equation, that is
Re-arrange for Q,
We can note that consider the Kinetic Energy will decrease the heat input.
Answer:
A.) 0.08 kJ/kg.K
B.) 207.8 KJ/Kg
C.) 0.808
Explanation:
From the question, the use of fluids mechanic table will be required. In order to get the compressor processes, the kinetic energy and the potential energy will be negligible while applying the ideal gas model.
Since the steam is a closed system, the carbon dioxide will be compressed adiabatically.
Please find the attached files for the solution and the remaining explanation.
Answer:
Option C = internal energy stays the same.
Explanation:
The internal energy will remain the same or unchanged because this question has to do with a concept in physics or classical chemistry (in thermodynamics) known as Free expansion.
So, the internal energy will be equals to the multiplication of the change in temperature, the heat capacity (keeping volume constant) and the number of moles. And in free expansion the internal energy is ZERO/UNCHANGED.
Where, the internal energy, ∆U = 0 =quantity of heat, q - work,w.
The amount of heat,q = Work,w.
In the concept of free expansion the only thing that changes is the volume.
Answer:While heat cycles cause oil to darken, soot causes oil to turn black
Explanation:
Most people associate soot with diesel engines, but gasoline engines can produce soot as well, particularly modern gasoline-direct-injection engines. ... Any finer filtration and the filter could catch dissolved additives in the motor oil
