A round pipe of varying diameter carries petroleum from a wellhead to a refinery. At the wellhead the pipe\'s diameter is 55.3 cm (0.553 m) and the flow speed of the petroleum is 12.9 m/s. At the refinery the petroleum flows at 6.13 m/s.
What is the volume flow rate of the petroleum along the pipe and what is the pipe\'s diameter at the refinery? in m^3/s
What is diameter in cm?
A bullet leaves a standard 45-caliber pistol (5.0-in. barrel) at a speed of 262 m/s. If it takes 1 ms to traverse the barrel, determine the average acceleration experienced by the 16.2-g bullet within the gun and after that compute average force e..
