What is the formula for calculating residence time?
the hydraulic residence time t is given by t=V/q where V is the volume in the tank and q is the volumetric flow rate. A theoretical residence time can be given by the relationship between concentration and time ln(C)=-(t/tav) where tav in this equation is the residence time.
What is Difference between residence time and space time?
Residence time is the time it takes a particle to complete the cycle. Space time is volume of the reactor over the velocity. If the volume does not change and the velocity remains constant then Residence time = space time, however, if there is a disturbance in the reactor (i.e., change in pressure, temp, ect.), then residence time does not equal to space time.
Green plants do not release large amounts of co2 all the time because they use co2 in the process of?
photosynthesis to produce oxygen and glucose. This process helps regulate the levels of CO2 in the atmosphere.
Can plants use as much co2 in photosynthesis as provided?
for each cycle they use 6 co2 molecules, but over time, they could use it all
How much CO2 will be produced by boiling a kettle each time?
Boiling a kettle typically releases around 0.15 kg (150 grams) of CO2 into the atmosphere each time, mostly from the energy it consumes during the boiling process.

What is residence time of gas?
Residence time in the boiler is typically two to five seconds, and the particles must be small enough for complete combustion to have taken place during this time. The ratio of gas occupied to a particular volume is called residence time based on gas.
What is Difference between residence time and space time?
Residence time is the time it takes a particle to complete the cycle. Space time is volume of the reactor over the velocity. If the volume does not change and the velocity remains constant then Residence time = space time, however, if there is a disturbance in the reactor (i.e., change in pressure, temp, ect.), then residence time does not equal to space time.
What is the average residence time of particles in a given system?
The average residence time of particles in a system is the average amount of time a particle stays within that system before leaving.
Can you provide an example of residence time in a chemical reactor?
Residence time in a chemical reactor refers to the average time a substance stays inside the reactor. For example, if a chemical reaction takes 10 minutes to complete in a reactor with a volume of 100 liters, the residence time would be 10 minutes.
Does the level of CO2 in the atmosphere rise or fall over time?
The level of CO2 in the atmosphere has been rising over time.
Which has the longest residence time on continents?
Methane has the longest residence time on continents among the greenhouse gases, due to its lower reactivity and slower rate of removal from the atmosphere.
What is a typical residence time for a stream in Ohio?
14 days
Is it legal to have an American residence permit and a Canadian residence permit at the same time?
No, you'll be asked to surrender one. It has happened many time before and none were successful to keep both.
How do you calculate the mean residence time in a system?
To calculate the mean residence time in a system, you divide the total amount of time a substance spends in the system by the total amount of that substance in the system. This gives you an average time that the substance remains in the system before leaving.
From where on the Apollo 13 did the CO2 come from?
it came from the austronauts. the co2 filter was broken .every time they breathed out, they exhailed co2.although the flight control helped fix that.
How do you calculate residence time in a system?
Residence time in a system is calculated by dividing the total volume of the system by the flow rate of material entering or leaving the system. This gives you the average amount of time that a substance remains in the system before exiting.
