Why volume PFR less than CSTR for same conversion and reaction rate?
The reason that a PFR requires less volume than a CSTR is the difference in residence time distribution between the reactors. Residence time is the amount of time molecules spend in the reactor which equal to v/vo (v=volume of the reactor and v0 is volumetric flow rate). Let us assume that we design a PFR and CSTR that have similar residence time i.e. ratio of volume v and v0 is the same and we are pumping about 100 molecule per minute to each reactor. In the case of PFR, all the 100 molecules will spend exactly the same time inside the reactor (v/v0). In the case of CSTR, things are little more complicated, once the 100 molecule hit the CSTR, they mixted instantaneously and thus some of these 100 molecules will leave from the reactor exit stream very early i.e. will spend much less time inside the reactor (less the v/v0) and of course some these 100 molecule will spend more time making the average residence time the same as the PFR. Therefore, with the chance that molecules will spend shorter time in CSTR, we try to compensate for that effect by making bigger reactors so the ratio of these molecules spending short period of time inside the reactor less and thus its performance is comparable to the PFR. Very logical and easy to understand explanation. But how to prove series of CSTR equals to one PFR which is having a volume of sum of all CSTRs?
What is the natural balance of a ninja?
The natural balance of a ninja is their balance of Yin and Yang, and their chakra. It is their inner focus and energy which can be both physical and mental balance that can allow a ninja to perform things they would not normally be able to do.
What are the various components of energy water and thermal balance?
energy balance: need carbohydrates such as sugars-glucose, amino acids-proteins, fats water balance: need water from drinking and eating, oxidative water meaning metabolic water and since its balance ; water loss through urine, feces and evaporation thermal balance: need metabolic heat, heat transferred by conduction, convention radiation and evaporation.
Could global climate be greatly altered if the earth's energy budget were out of balance?
true
If a stone is pushed from the top of the hill what kind of energy would it have halfway down the hill?
It would have an almost equal balance between gravitational potential energy and kinetic energy. The discrepancy comes from energy lost as heat via friction with the air and ground.
Diffeerence between CSTR and PFR on volume baises?
For simple understanding PFR can be imagined as multiple CSTR's in series. PFR has benefits of higher conversion rates, product uniformity & less energy losses. CSTR stands for Continuously Stirred Tank Reactor. PFR stands for Plug Flow Reactor.
What is the ticker symbol for coinstars?
Cstr

What is the balance between incoming solar energy and outgoing energy radiated into space called?
According to scientists, the balance between incoming solar energy and outgoing energy radiated into space is considered the earth energy budget.
Positive energy balance important when?
Positive energy balance is always important. Having your energy in balance keeps you from slipping too far into the negative and keeps you on a path toward happiness.

How do you enhance rate of reaction in CSTR?
rate of a reaction can be increased by increasing the temperature if the reactor
What is the balance between incoming and outcoming energy?
The balance between incoming and out coming energy is called radiation balance. you so right its in my science book
How would you use the word energy balance in a sentence?
i need an energy balance so i can keep up with my schoolwork
