Answer:
343 m/s
Explanation:
Velocity Formula (Wave): v = fλ
<em>v</em> - velocity
<em>f</em> - frequency
<em>λ</em> - wavelength
We are given <em>f</em> = 23.0 and <em>λ</em> = 14.9. Simply plug it into the formula:
v = 23.0(14.9)
v = 342.7
v ≈ 343
Answer: Option (a) is the correct answer.
Explanation:
The given data is as follows.
= 4.19
= 1.9
Heat of vaporization () at 1 atm and is 2259 kJ/kg
= 0
Therefore, calculate the enthalpy of water vapor at 1 atm and as follows.
= +
= 0 + 2259 kJ/kg
= 2259 kJ/kg
As the desired temperature is given and effect of pressure is not considered. Hence, enthalpy of liquid water at 10 bar and is calculated as follows.
=
= 334.781 kJ/kg
Hence, enthalpy of water vapor at 10 bar and is calculated as follows.
=
= 2410.81 kJ/kg
Therefore, calculate the latent heat of vaporization at 10 bar and as follows.
=
= 2410.81 kJ/kg - 334.781 kJ/kg
= 2076.029 kJ/kg
or, = 2076 kJ/kg
Thus, we can conclude that at 10 bar and latent heat of vaporization is 2076 kJ/kg.
