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 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 the conditions of steam velocity while flow through steam nozzle?
Nozzles are designed to increase the steam velocity.
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!!!!!!
How can you calculate water velocity from flow rate or diameter of pipe?
if u r talking about presuure drop then it can be easily calculate with the help of relation 4flv*v/2gd in that f is the friction factor which is different for vraious type of flow for that u have to search a good book of fluid mechanics, v is the velocity. length of pipe and d is diameter of pipe
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 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
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
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
Differentiate between steady flow and pipe unsteady flow?
The velocity is constant in a steady flow pipe while in the unsteady flow the velocity is not constant.
What is the equation for fluid flow?
is the equation for flow velocity
Difference between turbulent flow and streamlined flow?
Streamline flow:The flow of a fluid is said to be streamline (also known as steady flow or laminar flow), if every particle of the fluid follows exactly the path of its preceding particle and has the same velocity as that of its preceding particle when crossing a fixed point of reference.Turbulent flow:The flow of a fluid is said to be turbulent or disorderly, if its velocity is greater than its critical velocity. Critical velocity of a fluid is that velocity up to which the fluid flow is streamlined and above which its flow becomes turbulent. When the velocity of a fluid exceeds the critical velocity, the paths and velocities of the fluid particles begin to change continuously and haphazardly. The flow loses all its orderliness and is called turbulent flow.
What is difference between flow rate and flow velocity in flow tubes?
velocity is the speed of the flow (for example, meters/sec.) Flow rate is the volume per unit time (example: liters/sec.)
What is critical velocity in fluid flow?
The flow of a liquid remains steady or orderly only so long as its velocity does not exceed a certain limiting value for it, called critical velocity.
How does a streams gradient affect of velocity?
The steeper the gradient, the higher the velocity of flow.
What are limitations of velocity of flow in a pipeline?
The velocity of flow in any pipe is determined by three things. The internal pipe diameter, the mass flow rate of the liquid and the fluid density.
Where the velocity of blood flow is the lowest?
capillaries!
