G In an absorption refrigeration unit, a mixture of LiBr solution is pumped at a rate of 0.75 kg/s to the generator which is at a temperature of 80oC, while the condenser is at 35oC, the evaporator is at 15oC, and the absorber is at 25oC. What is the concentration of LiBr solution leaving the absorber

Explanation:

Pump rate of LiBr = 0.75kg

Temperature of the generator = 80

Temperature of evaporator = 15

Temperature of absorber = 25

Condenser = 35

Concentration of LiBr leaving the absorber = 0.75 × 25 = 18.75 /35 = 0.536

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
