Given : The capacity of a nuclear power plant is 500 MW. If the efficiency of power plant is 60%
To Find : the mass (loss) that converted into energy per hour is
1/50 g
1/60 g
1/30 g
1/120 g
Solution:
The capacity of a nuclear power plant is 500 MW
the efficiency of power plant is 60%
Let say Energy to be produced = x
Energy produced = (60/100)x = 3x/5
=> 3x/5 = 500 MW
=> x = 2500/3 MW
Energy Produced per hour = 3600 * 2500/3 M Joule
= 1200 * 2500 M Joule
= 3000000 M Joule
= 3 * 10¹² Joule
E = mC²
C = 3 * 10⁸ m/s
=> m * ( 3 * 10⁸)² = 3 * 10¹²
=> m = 1/ 3 * 10⁴ kg
=> m = 1000 / 3 * 10⁴ g
=> m = 1/ 30 g
mass (loss) that converted into energy per hour = 1/ 30 g
