A process is carried out for the feed mixture of 80% air and 20% CO2, the compressor recovered 50% of CO2, what is the exit pressure of the compressor, if the partial pressure of CO2 is 15 mm Hg? Correct Answer 135 mm Hg

Exit components, CO2: 0.2*0.5 = 0.1, air: 0.8, => yCO2 = 0.1/0.9 = 0.111, => Total exit pressure = 15/0.111 = 135 mm Hg.

Five friends went for a trip where each carried a certain number of apples with them. The number of apples carried by C was 1 less than that by D, which was 5 more than the number of apples carried by E. The total number of apples carried by A and B both was equal to the average number of apples carried by C, D and E. If D carried more apples than B and they together carried 14 apples, which of the following is a possible value of the apples carried by A?

oil and kerosene are present in ratio of 5 : 7 in a liquid. Few litres of mixture of mixture are replaced with petrol. Ratio of oil : kerosene: petrol is 35 : 49 : 18 respectively. Amount of oil removed from mixture is 21 litres less than that of petrol added to the mixture. And amount of oil removed is 6 litres less than that of difference mentioned. Petrol is replacing the mixture removed hence; quantity of mixture is not changing. What is the difference between quantity of kerosene in old mixture and amount of oil in new mixture?
An irreversible aqueous phase reaction, A + B → P, is carried out in an adiabatic mixed flow reactor. A feed containing 4 kmole/m3 of each A and B enters the reactor at 8 m3/hr. If the temperature of the exit stream is never to exceed 390 K, what is the maximum inlet feed temperature allowed?
(Data: Heat of reaction = -50 kJ/mole, Density of the reacting mixture = 1000 kg/m3, Specific heat of reacting mixture = 2 kJ/kg.K)
The above data can be assumed to be independent of temperature and composition.
