![Q5) A continuous stirred tank heater has holdup capacity of 60 kg and receives two feed streams
of water (Cp=4.2 kJ/kg K). Mass flow rate of first stream is 280 kg/min while the other is 200
kg/min. The temperature of the two feed streams is 40°C. An electrical heater provides a constant
heat input of (Q=100 kW). If the temperature of the first inlet stream is suddenly increase by 50%
while the second remain constant, Find
(a) Steady-state outlet temperature
(b) Process overall transfer function.
(c) Process outlet temperature response and sketch it
Q6) Raoult's law gives the vapor mole fraction y(t) at equilibrium as a function of temperature
and liquid mole fraction, x(t) as follows:
y(t) = P° (t)x(t)
where p°(t) is the vapor pressure given by Antoine's equation as:
p°(t) = e4-B/[T(t)+c]
Find the linear model for the vapor mole fraction y(t) in terms of x(t) and T(t). Evaluate the model
for benzene at pressure = 1 atm, temperature= 95°C and a liquid mole fraction x= 50%. The
Antoine constants for Benzene are: A=15.9008, B=2788.51°C, and C = 220.80°C.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1315f8c0-9b51-4214-9415-f1386f2c9f12%2Fc0a2febb-f068-4887-b2e6-7c336ac4315e%2Fozimr4f_processed.jpeg&w=3840&q=75)
