WebSep 12, 2024 · A spacecraft is moving in gravity-free space along a straight path when its pilot decides to accelerate forward. He turns on the thrusters, and burned fuel is ejected at a constant rate of 2.0 × 10 2 k g / s, at a speed (relative to the rocket) of 2.5 × 10 2 m / s. WebNov 26, 2024 · The volumetric flow rate formula may be written in the alternative (read: way more useful) form. You can first calculate the volume of a portion of the fluid in a channel as: V = A\cdot l V = A ⋅ l where A is a cross-sectional area of the fluid, and l l is the width of a given portion of the fluid.
