What is space velocity mean?
Definition of space velocity 1 : the velocity of a star’s motion relative to the sun as determined from its proper motion, distance, and radial velocity. — called also space motion.

What is space velocity chemistry?
Space velocity (chemistry), the relation between volumetric flow rate and reactor volume in a chemical reactor.
How do you find space velocity?
By definition, space velocity can be expressed mathematically as SV = Vo / V. In this expression, Vo represents the volumetric flow rate of the reactants entering the reactor and V represents the volume of the reactor itself.
How much is space velocity?
Space Velocity signifies that how many reactor volumes of feed can be fed in unit time (for instance, a reactor with a space velocity of 1 hr−1 is able to process feed equivalent to one time the reactor volume each hour). It is reciprocal of the reactor space-time. Mathematically, it is expressed as SV = Vo / V.
What is unit of space velocity?
Explanation: Space velocity is the ratio of volumetric flow rate to volume. It has the unit hr-1.
How do you calculate gas hourly space velocity?
Gas hourly space velocity (GHSV) = Volumetric flow rate of reactant or exhaust gas/External volume of catalyst monolith.
How do you calculate Space time reactor?
The Space time, tau, is obtained by dividing the reactor volume by the volumetric flow rate entering the reactor: Space time is the time necessary to process one volume of reactor fluid at the entrance conditions.
What is space-time and space velocity?
SPACE TIME: TAU = vo/V. Time required to process one reactor volume of fluid based on entrance conditions. The uniteis are of time (s, min, h, etc.) SPACE VELOCITY: in principle is the inverse of the space time: SV = V/vo. The units are of time-1.
What is the unit of space velocity?
What is space time yield?
Often the performance of a reactor is given relative to the catalyst mass or vol- ume, so that reactors of different size or construction can be compared with one. another. This quantity is known as the space–time yield (STY ): STY =
How do you calculate space-time reactors?
What is liquid hourly space velocity (lhsv)?
As the Liquid Hourly Space velocity (LHSV) is the ratio of the volumetric flow rate (hourly) of the liquid feed to the volume of the catalyst present in the reactor. So, LHSV is reciprocal of the space-time.
What is space velocity and how is it calculated?
What is Space Velocity? Space velocity = flow rate of the feeds/ volume of the reactor (or volume of the catalyst) Space Velocity signifies that how many reactor volumes of feed can be fed in unit time (for instance, a reactor with a space velocity of 1 hr−1 is able to process feed equivalent to one time the reactor volume each hour).
What is gas hourly space velocity (ghsv)?
Gas hourly space velocity (GHSV) is a similar method for relating the reactant gas flow rate to the reactor volume. GHSV is usually measured at standard temperature and pressure.
What is the unit of space velocity in a catalytic reactor?
The most common unit of <2rel is bed volumes per hour (BV/li). Space velocity is also used in catalytic reactors, especially in three-phase fixed-beds, and is referred to as liquid hourly space velocity (LHS V) for the liquid phase, and gas hourly space velocity (GHSV) for gas phase.
