Explanation:
force that acts on a body moving in a circular path and is directed towards the centre around which the body is moving
In physics, gravitational acceleration is the free fall acceleration of an object in vacuum — without any drag. This is the steady gain in speed caused exclusively by the force of gravitational attraction
A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). This numerical value for the acceleration of a free-falling object is such an important value that it is given a special name.
Space velocity = flow rate of the reactants/ the reactor volume. (or the catalyst bed volume) which indicates how many reactor volumes of feed can be treated in a unit time (for instance, a reactor with a space velocity of 7 hr−1 is able to process feed equivalent to seven times the reactor volume each hour).
