How to Obtain the Transfer Function for a Heating System with Dual Tanks?

In summary, the conversation is about obtaining a transfer function for a tank with a heater placed inside, in order to maintain the liquid temperature at 45C. The tank is placed inside another tank, with the heating coil in the inner tank to distribute heat to the liquid in the outer tank. The outer tank has inlets and outlets, but the inner tank has no inflow or outflow. The desired temperature for the outer tank is 40C. The person is seeking guidance on how to obtain the transfer function for analysis and controlling purposes.

i need a help to obtain transfer function for a tank, where a heater is placed. the liquid temperature should be maintained at 45C . no inlet or out let. how to obtain the transfer function?? for analysisng about the controller?

Actually the system is like this. a tank is placed inside another tank. consider outer tank as A and inner as B. the heating coil is placed inside tank B, for the purpose of heat distribution in the liquid inside tank A. tank A has inlets and outlet.
but tank B water level is stationary no inflow or out flow. assume there won't be a mass loss as vapour.
the required temp in outer tank A is 40 C. so i have build the relationship and obtain transfer function.

please guide me . pleasezzzzz
 

FAQ: How to Obtain the Transfer Function for a Heating System with Dual Tanks?

What is a transfer function?

A transfer function is a mathematical representation of the relationship between the input and output of a system, expressed in terms of a complex variable.

How is a transfer function used?

A transfer function is used to analyze the behavior of a system and predict its output for different inputs. It is also used in the design and control of systems.

What does the transfer function tell us about a system?

The transfer function provides information about the system's dynamics, stability, and frequency response. It can also reveal the presence of poles and zeros, which are important in system analysis and design.

How is a transfer function different from a frequency response function?

A transfer function describes the input-output relationship of a system in the frequency domain, while a frequency response function describes the system's output as a function of frequency without considering the input. The transfer function can be obtained from the frequency response function by dividing the output by the input.

How is a transfer function derived?

A transfer function can be derived using the Laplace transform of the system's differential equations. It can also be obtained experimentally by measuring the input and output signals of a system and calculating their ratio.
