Question
Chapter 1, Problem 1.4E
Interpretation Introduction
Interpretation:
Whether the feedback control system is utilized by a typical microwave oven to set the cooking temperature or determine if the food is cooked or not, is to be determined. Also, a technique used for this purpose is to be stated. Any disadvantages which are there in this approach are to be mentioned.
Concept introduction:
A control system is a system that regulates or monitors the behavior or working of other devices/systems using control loops. It can be used to control single devices or large industrial processes. There are two types of control system which can be used to control the processes. These are feedback control system and feedforward control system.
Feedback control systems consider the output of the system and then compares it with the desired value to adjust the measured value to provide accurate results whereas in feedforward control system, disturbances are taken into account beforehand and they are rectified to control it from deviating from the desired set point.

A forward feed double-effect vertical evaporator, with equal heating areas in each effect, is fed with 5 kg/s of a liquor of specific heat capacity of 4.18 kJ/kg K. and with no boiling point rise, so that 50 per cent of the feed liquor is evaporated. The overall heat transfer coefficient in the second effect is 75 per cent of that in the first effect. Steam is fed at 395 K and the boiling point in the second effect is 373 K. The feed is heated by an external heater to the boiling point in the first effect. It is decided to bleed off 0.25 kg/s of vapour from the vapour line to the second effect for use in another process. If the feed is still heated to the boiling point of the first effect by external means, what will be the change in steam consumption of the evaporator unit?
