Suppose that a nuclear reactor is full with 1 million liters of contaminated (radioactive) water. Flushing of the contaminated water by flowing-in uncontaminated water at a rate of 1000 liters per day is being considered.
Assuming ideal mixing of contaminated and uncontaminated waters inside the reactor, calculate how long will it take to flush out 95% of the original contaminated water
Calculate how much energy in the form of heat is available from 100mL of this mixture and compare it with the amount from pure gasoline. assume the densities of ethanol and gasoline are
