I dont know the pop but usually in bad areas people can’t afford many things and their health is bad and so people die at younger ages. So when the stress rate is high and the population increases, people start having their life’s at young ages. This makes the population increase more.

Why is the definition for second based on the Cesium 133 atom?
jarptica [38.1K]

Answer:

  The rate of vibrations of the atoms is consistent

Explanation:

A second is defined as 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom.

The definition applies when the atom is in isolation at a temperature of absolute zero. Adjustments must be made for the conditions that can be maintained in practice.

Such radiation is determined by the laws of quantum mechanics, so is extremely consistent.

Steam enters a turbine operating at steady state with a mass flow of 10 kg/min, a specific enthalpy of 3100 kJ/kg, and a velocit
Natali [406]

Answer:

\dot W_{out} = 133.327\,kW

Explanation:

The model for the turbine can be derived by means of the First Law of Thermodynamics:

-\dot Q_{out}-\dot W_{out} +\dot m \cdot \left[(h_{in}-h_{out})+\frac{1}{2}\cdot (v_{in}^{2}-v_{out}^{2}) + g\cdot (z_{in}-z_{out})\right] =0

The work produced by the turbine is:

\dot W_{out}=-\dot Q_{out} +\dot m \cdot \left[(h_{in}-h_{out})+\frac{1}{2}\cdot (v_{in}^{2}-v_{out}^{2}) + g\cdot (z_{in}-z_{out})\right]

The mass flow and heat transfer rates are, respectively:

\dot m = (10\frac{kg}{min})\cdot (\frac{1\,min}{60\,s} )

\dot m = 0.167\,\frac{kg}{s}

\dot Q_{out} = (0.167\,\frac{kg}{s} )\cdot (1.1\times 10^{3}\,\frac{J}{kg} )

\dot Q_{out} = 183.7\,W

Finally:

\dot W_{out} = -183.7\,W + (0.167\,\frac{kg}{s} )\cdot \left(8\times 10^{5}\,\frac{J}{kg} -562,5\,\frac{J}{kg} +29.43\,\frac{J}{kg} \right)

\dot W_{out} = 133.327\,kW
