Displacement Efficiency Formula:
| From: | To: |
Displacement Efficiency is the ratio of flowing period to detention period. It measures how effectively a fluid is displaced through a system relative to the time it remains in the tank or treatment facility.
The calculator uses the Displacement Efficiency formula:
Where:
Explanation: The formula calculates the efficiency by dividing the time taken for flow through the system by the average detention time of the fluid in the tank.
Details: Accurate calculation of displacement efficiency is crucial for optimizing fluid flow systems, improving treatment processes, and ensuring efficient operation of tanks and treatment facilities.
Tips: Enter the flowing through period and detention time in seconds. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is a good displacement efficiency value?
A: Values closer to 1 indicate higher efficiency, meaning the fluid flows through the system more effectively relative to its detention time.
Q2: Can displacement efficiency be greater than 1?
A: Yes, if the flowing through period exceeds the detention time, the efficiency value will be greater than 1, indicating very efficient displacement.
Q3: What units should I use for input values?
A: Both flowing through period and detention time should be entered in seconds for consistent calculation.
Q4: How does detention time affect displacement efficiency?
A: Longer detention times typically result in lower efficiency values, as the fluid remains in the system for a longer period relative to the flow time.
Q5: Is this calculation applicable to all fluid systems?
A: While the basic principle applies to many systems, specific applications may require additional factors to be considered for accurate efficiency measurement.
