The correct answer is wrong with the correct spelling correct
Answer with Explanation:
The relation between power and energy is
Since the nuclear reactor operates at 1200 MW throughout the year thus the energy produced in 1 year equals
Now from the energy mass equivalence we have
where
'c' is the speed of light in free space
Thus equating both the above values we get
Since it is given that 1 kg of mass is 34% effective thus the mass reuired for the reactor is
Thus 1.235 kg of nuclear fuel is reuired for operation.
Answer:
a) 0.39795 kJ/K
b) 79.589.37 kJ
Explanation:
m = Mass of air = 2 kg
Temperature = 200 K
P₁ = Initial pressure = 300 kPa
P₂ = Final pressure = 600 kPa
R = mass-specific gas constant for air = 287.058 J/kgK
a) For isentropic process
∴ Entropy is generated in the process is 0.39795 kJ/K
b)
∴ Amount of lost work is 79.589.37 kJ
