when you have the vescosity to react with the liquid or the substance in the being of the making
Volumetric flow is L^3/T, a cubic length divided by time (cubic meters per second, for example.) Velocity is L/T (meters per second or miles per hour). To get velocity from volumetric flow, you divide the volumetric flow by the cross-sectional area (L^2) of whatever the liquid is flowing through. If you have .5 ft^3/s of water flowing through a pipe with a 1.5 inch diameter, convert 1.5 inches to feet: 1.5/12 = .125 ft, then find the cross-sectional area: (pi/4)(.125^2) = .01227 ft^2. Then .5 ft^3/s by the area and get 40.7 ft/s, which is about 27.75 mph.
The relationship of mass flow rate of to volumetric flow rate is
m-dot=V-dot/v
where m-dot is the mass flow rate, v is the specific volume of the water, and V-dot is the volumetric flow rate.
mass flow rate and volume flow rate both are come from conservation of mass equation.
if assumption are incompressible fluid and fixed control volume surface ,it means density and volume become constant ,result equation show volume flow rate .it doesn't matter flow is steady or unsteady.
another case if take assumption as steady flow than result show us mass flow rate.
so before convert mass flow rate into volume flow rate we have to take assumptions.
dm=integration(density*dv) (show mass flow rate) ;where v=volume
dv=integration(A.dV) (show volume flow rate)
;V=velocity vector & A=area of surface (direction is perpendiculr to surface toward outside) here this is dot product
dm=integration(density(A.dV))
You need to use the formula Q = AV.
Q = flow rate, A = Area, V = velocity.
A needs to be calculated. For example if a fluid is flowing through a pipe of Diameter 10 cm then its radius = 5 cm. Its area will be = pi. r. r
Now put the values in the formula. V = Q/A
Flow rate divided by the area will give the velocity of the fluid. You have thus converted flow rate to velocity. Area can change depending on the shape of the object through which the fluid is flowing.
Thank you for reading.
you divide the volume by time. time how long it takes for the fluid to flow.
Orfice meters,venturi meters, rotameters, and displacement meters are used extensively in industrial operations for measuring the rate of liquid flow.
you take your unit of measurement ( usually volume ) and divide it by seconds. ML/S
division of mass flowrate [e.g. kg/s] by density [e.g. kg/l] gives the volumetric flowrate [e.g. l/s]
it can be asumed as mass flow rate per unit area
velocity is the speed of the flow (for example, meters/sec.) Flow rate is the volume per unit time (example: liters/sec.)
mass
The flow rate may be defined by the quantity of a fluid which can be transportted through a hole with a given area in an unit of time.
These have a inverse relation. You will need to know the discharge and the incoming pressure in order to find out the mass flow rate.
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.
it can be asumed as mass flow rate per unit area
When equivalence ratio increase, the actual air-fuel ratio decrease, which mean the mass flow rate of air is decrease. So, the volume flow rate of air is dercreasing and its mean the velocity is decreasing.
velocity is the speed of the flow (for example, meters/sec.) Flow rate is the volume per unit time (example: liters/sec.)
You cannot. Force = Mass*Acceleration or Mass*Rate of change of Velocity.
Using conservation of mass: mass flow rate = ρ * V * A where ρ= density, V= velocity, and A= cross sectional area therefore since massin = massout therefore: (ρ*V*A)in = (ρ*V*A)out
Force equals the mass times the rate of change of the velocity.
mass
With the increase in flow rate the velocity of the fluid increases. and with the increase in velocity the pressure decreases, because there will be pressure drop (Refer Bernoulli's Theorm). So with increase in Flow rate the pressure decreases.
the ratio of the distillate mass flow rate to the mass flow rate of the steam used
CFM is a rate of flow. KW is a rate of energy. You really cannot convert them.
Flow rate is diameter of hole*velocity, so the higher the velocity the higher the flow rate.
