Chemical Reaction Engineering Pick out the wrong statement pertaining to space velocity of flow reactors. The space velocity of 3 hr⁻¹ means that three reactor volumes of feed at specified conditions are being fed into the reactor every hour None of these The unit of space velocity is (time)⁻¹ The space velocity of 3 hr⁻¹ means that one third reactor volume of feed at specified conditions are being fed into the reactor The space velocity of 3 hr⁻¹ means that three reactor volumes of feed at specified conditions are being fed into the reactor every hour None of these The unit of space velocity is (time)⁻¹ The space velocity of 3 hr⁻¹ means that one third reactor volume of feed at specified conditions are being fed into the reactor ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering An irreversible aqueous phase reaction, A + B → P, is carried out in an adiabatic mixed flow reactor. A feed containing 4kmole/m³ of each A and B enters the reactor at 8m³ /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 = 1000kg/m³, Specific heat of reacting mixture = 2kJ/kg.K)The above data can be assumed to be independent of temperature and composition. 390 290 490 190 390 290 490 190 ANSWER DOWNLOAD EXAMIANS APP
