Space velocity may refer to: Space velocity (astronomy) , the velocity of a star in the galactic coordinate system Space velocity (chemistry) , the relation between volumetric flow rate and reactor volume in a chemical reactor
In 2012, the head of AP Grading, Trevor Packer, stated that the reason for the low percentages of 5s is that "AP World History is a college-level course, & many sophomores aren't yet writing at that level." 10.44 percent of all seniors who took the exam in 2012 received a 5, while just 6.62 percent of sophomores received a 5.
The residence time of a fluid parcel is the total time that the parcel has spent inside a control volume (e.g.: a chemical reactor, a lake, a human body).The residence time of a set of parcels is quantified in terms of the frequency distribution of the residence time in the set, which is known as residence time distribution (RTD), or in terms of its average, known as mean residence time.
The history of fluid mechanics is a fundamental strand of the history of physics and engineering.The study of the movement of fluids (liquids and gases) and the forces that act upon them dates back to pre-history.

Oberth was a space flight theorist and had never built a rocket, but he tested small liquid propellant thrust chambers in 1929–30 which were not advances in the "state of the art". [ 64 ] : 273, 275 In 1922 Oberth asked Goddard for a copy of his 1919 paper and was sent one though Goddard was distrustful of the militaristic Germans.
Superficial velocity (or superficial flow velocity), in engineering of multiphase flows and flows in porous media, is a hypothetical (artificial) flow velocity calculated as if the given phase or fluid were the only one flowing or present in a given cross sectional area. Other phases, particles, the skeleton of the porous medium, etc. present ...
A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a nearly constant volume independent of pressure. It is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape.
