Explanation
The correct answer is Heat transfer.
Correct answer
A. Heat transfer
Explanation
The correct answer is Heat transfer.
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?
If f = moles of vapour present per mole of feed, then the slope of feed line is (McCabe- Thiele method) ________?
Can a cooling tower cool water below the wet bulb temperature of inlet air?
Water is normally used as a coolant in the heat exchange equipments mainly because of its________?
Except for monatomic gases, the molal heat capacity at constant volume for all gases is ________ Kcal/Kg mole.° K?
Nylon-6 is manufactured from ________?
