Aliquid stream containing 50.0 mole% benzene and the balance toluene at 25°c is fed to a continuous single-stage evaporator at a rate of 1320 mol/s. the liquid and vapor streams leaving the evaporator are both at 95.0°c. the liquid contains 42.5 mole% benzene and the vapor contains 73.5 mole% benzene. calculate the heating requirement for this process in kw. using raoult’s law (section 6.4b) to describe the equilibrium between the vapor and liquid outlet streams, determine whether or not the given benzene analyses are consistent with each other. if they are, calculate the pressure (torr) at which the evaporator must be operating; if they are not, give several possible explanations for the inconsistency.

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j

i'm assuming that it's c.) red bank..

b is the correct answer

mark me brainliest and hope this

what is the question?
