What are a completely mixed flow reactor and its concentration characterisrtics?
a completely mixed reactor. the concentration in the reactor is the same that flows our of the reactor
What is PF in chemical reaction engineering?
The plug flow reactor model (PFR, sometimes called continuous tubular reactor, CTR) is normally the name given to a model used in chemical engineering to describe chemical reactions in continuous, flowing systems of cylindrical geometry.

What is pipe flow?
Pipe flow refers to the movement of fluid (liquid or gas) through a confined space, typically within a pipe or duct. It is characterized by various parameters including flow rate, velocity, pressure, and viscosity of the fluid. The study of pipe flow is essential in engineering and fluid dynamics for designing efficient systems in industries like water supply, oil and gas, and HVAC. Flow can be classified as laminar or turbulent, depending on the fluid's velocity and viscosity, which influences the flow behavior and energy loss.
What are the conditions for reaction between Ethylene oxide and water in a plug flow reactor or in a Continuous Stirred Tank Reactor?
The Feed conditons entering are at 25 deg c with 101.3 kpa the reactor is a cstr operating at 65deg c the product if ethylene glycol!!!!!!
What is the equation for water flow in construction?
the velocity of water flow within a drainage pipe; the equation is V=L/t L= Length t=time. Then the flow rate; Fr=A*V, Where A= sectional area and V = velocity.
What is meant by vhsv space velocity?
Space velocities are typically used to describe catalytic reactors, and are denoted as volume hourly space velocity, VHSV. VHSV = Volume flow/catalyst mass
Can tubular flow reactor can be considered as bubble column?
It depends. The bubble column reactor creates a cross current flow of liquid and gas and the focus is to dissolve the gas into solution so that the necessary chemical reactions can take place. So a key criteria is a two-phase flow of gas and liquid. If by tubular you mean a horizontal pipe, it can be possible to do the same thing but you have to ensure that phase separation does not occur within the horizontal reactor and therefore have to provide some form of mixing to ensure the reaction takes place. A bubble column is ideal for this, but again, it can be done in the other arrangement as well.

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.
Stream velocity is faster in a?
Stream velocity is dependent of four things. They are, the flow type, the gradient, the channel shape, and the discharge of the stream. Streams will flow faster in narrow channels on steeper grades.
How do you calculate flow velocity in a fluid system?
Flow velocity in a fluid system can be calculated by dividing the flow rate of the fluid by the cross-sectional area of the pipe or channel through which the fluid is flowing. The formula for calculating flow velocity is: Velocity Flow Rate / Cross-sectional Area.
Why velocity of flow will decrease with increase in peripheral speed of francis turbine?
the peripheral velocity of the turbine is the around velocity. the increase in the velocity of the peripheral will decrease the velocity of the flow towards the turbine
Where is the velocity of a stream fastest?
The velocity of a stream is usually fastest in the middle of the channel, away from the banks where friction against the sides slows down the water flow. This is due to lower friction and more space for the water to flow without obstruction.
How can one determine the flow velocity in a fluid system?
One can determine the flow velocity in a fluid system by measuring the rate of flow and the cross-sectional area of the system. By dividing the flow rate by the cross-sectional area, the flow velocity can be calculated.
What is the difference between space time and holding time in chemical reactors?
Space Time is the time necessary to process one reactor volume of fluid based on entrance conditions (holding time or mean residence time)This is the time it takes for the amount of fluid that takes up the entire volume of the reactor to either completely enter or exit the reactor. It is also called holding time or mean residence time. e.g. a space time of 2mins.means every 2mins one reactor volume of feed at specified conditions is being treated by the reactor.
What is the relationship between flow velocity and area?
Flow velocity and area are inversely related in a fluid system. When the area decreases, the flow velocity increases, and vice versa, according to the principle of continuity, which states that the product of cross-sectional area and flow velocity remains constant in an enclosed system with steady flow.
