To perform an energy balance for a CSTR (continuous stirred-tank reactor), you need to account for the energy input (heat, work) and output (cooling, agitation losses, heat exchange with surroundings) in the system. The energy balance equation typically involves the heat generated or consumed in the reaction, the heat capacity of the reactor contents, and the temperature changes within the reactor. By summing up these energy terms, you can determine the overall energy balance for the CSTR system.

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.
What kind of energy does clouds that produce lightning have?
Clouds that produce lightning have electrical energy. This energy is generated by the separation of positive and negative charges within a cloud, which results in the discharge of lightning as a way to balance these charges.
What is the Incoming radiation minus outgoing radiation?
Incoming radiation minus outgoing radiation is known as the net radiation balance. This balance determines the Earth's energy budget, with excess incoming radiation leading to warming of the planet, while excess outgoing radiation results in cooling. The net radiation balance is a key factor in understanding the Earth's climate system.
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 radiational balance?
Radiation balance is the balance between incoming energy and outgoing energy
What causes positive energy balance and what are the effects of positive energy balance?
Positive energy balance is when energy intake exceeds expenditure weight is gained
What is the balance between incoming and outgoing energy called?
The balance between incoming and outgoing energy is called radiation balance.
How do you enhance rate of reaction in CSTR?
rate of a reaction can be increased by increasing the temperature if the reactor
What balance between incoming and outgoing energy is called?
The balance between incoming and outgoing energy is called radiation balance.
How would you use the word energy balance in a sentence?
Energy balance refers to the relationship between the energy consumed through food and drinks and the energy expended through physical activity and metabolic processes. Maintaining a positive energy balance, where energy intake exceeds energy expenditure, can lead to weight gain, while a negative energy balance can result in weight loss.
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 is 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.
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.
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
