i would appriciate your help. thanks Question 4-(20 marks) (a) Briefly describe the characteristics of an operational amplifier (op-amp) and describe two examples of where It can be used in signal conditioning circults (b) (4 marks) The level of liquid In a vertical cylindrical tank is controlled by a two-position level controller. The following data was recorded for the tank and flow system over a period of stable operation tank diameter. inlet flow rate (inlet valve open5 /min inlet flow...
A1 A water heating system is represented by the block diagram shown in figure A1. The valve mixes hot and cold water to obtain the desired water temperature using an integral controller of gain K. The water temperature is controlled by sensing the output temperature 0o and comparing with the desired temperature 0d. Write down an expression, in Bode form, for the open-loop frequency response function in terms of K and frequency o. Hence draw the open-loop Bode plot for...
summatize the following info and break them into differeng key points. write them in yojr own words apartus 6.1 Introduction—The design of a successful hot box appa- ratus is influenced by many factors. Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
