Flow speed equation

WebThe term , where is the speed, and is the fuel consumption rate, is called the specific range (= range per unit mass of fuel; S.I. units: m/kg). The specific range can now be determined as though the airplane is in quasi-steady-state flight. Here, a difference between jet and propeller-driven aircraft has to be noticed. Web3. (blood) pressure = F/area = m*a/area = m*v / area*second. 1) this area is the whole area meeting the blood inside the vessel. 2) which is different from the areas above (that is the dissected 2-d circle) 3) when dilation happens, the area of 2-d circle is growing. while the whole area of 1) stays still.
