Time Constant for Mixing Process Solution

STEP 0: Pre-Calculation Summary

Formula Used

Time Constant = (Volume/Volumetric Flow Rate of Feed to Reactor)
𝜏 = (V/v_o)
This formula uses 3 Variables

Variables Used

Time Constant - (Measured in Second) - Time Constant (𝜏) is the time required by the response to reach 63.2% of its ultimate value. If 𝜏 is high that means system will response fast.
Volume - (Measured in Cubic Meter) - Volume is the amount of space that a substance or object occupies or that is enclosed within a container.
Volumetric Flow Rate of Feed to Reactor - (Measured in Cubic Meter per Second) - The Volumetric Flow Rate of Feed to Reactor gives the volume of the reactants stream being fed to the reactor per unit time.

STEP 1: Convert Input(s) to Base Unit

Volume: 63 Cubic Meter --> 63 Cubic Meter No Conversion Required
Volumetric Flow Rate of Feed to Reactor: 10 Cubic Meter per Second --> 10 Cubic Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

𝜏 = (V/v_o) --> (63/10)

Evaluating ... ...

𝜏 = 6.3

STEP 3: Convert Result to Output's Unit

6.3 Second --> No Conversion Required

FINAL ANSWER

6.3 Second <-- Time Constant

What is Time Constant?

Time constant means how fast the system reaches the final value. As smaller the time constant, as faster is the system response. If time constant is larger, system goes to move slow. The time constant for first order system can be defined as the time it takes for the step response to rise up to 63% or 0.63 of its final value. The reciprocal of time constant, is 1/seconds or frequency.

What is Process Dynamics and Control?

Process Dynamics is concerned with analyzing the dynamic (i.e., time dependent) behavior of a process in response to various types of inputs. In other words, it is the behavior of a process as time progresses.

How to Calculate Time Constant for Mixing Process?

Time Constant for Mixing Process calculator uses Time Constant = (Volume/Volumetric Flow Rate of Feed to Reactor) to calculate the Time Constant, The Time Constant for Mixing Process formula is defined as the speed with which the measured Process Variable (PV) responds to changes in the Controller Output (CO). More specifically it represents the time needed for the PV to reach 63.2% of its total and final change. Time Constant is denoted by 𝜏 symbol.

How to calculate Time Constant for Mixing Process using this online calculator? To use this online calculator for Time Constant for Mixing Process, enter Volume (V) & Volumetric Flow Rate of Feed to Reactor (v_o) and hit the calculate button. Here is how the Time Constant for Mixing Process calculation can be explained with given input values -> 6.3 = (63/10).

FAQ

What is Time Constant for Mixing Process?

The Time Constant for Mixing Process formula is defined as the speed with which the measured Process Variable (PV) responds to changes in the Controller Output (CO). More specifically it represents the time needed for the PV to reach 63.2% of its total and final change and is represented as 𝜏 = (V/v_o) or Time Constant = (Volume/Volumetric Flow Rate of Feed to Reactor). Volume is the amount of space that a substance or object occupies or that is enclosed within a container & The Volumetric Flow Rate of Feed to Reactor gives the volume of the reactants stream being fed to the reactor per unit time.

How to calculate Time Constant for Mixing Process?

The Time Constant for Mixing Process formula is defined as the speed with which the measured Process Variable (PV) responds to changes in the Controller Output (CO). More specifically it represents the time needed for the PV to reach 63.2% of its total and final change is calculated using Time Constant = (Volume/Volumetric Flow Rate of Feed to Reactor).
