Helium gas is flowing steadily through the pipe shown above. The diameter of the pipe at the left end is 2.00×10-2 m and at the right is 1.00×10-2 m. The flow is slow enough that the density of the gas remains essentially constant. The volume flow rate is 2.00×10-3 m3/s. The speed of the gas in the right end of the pipe is how many times the speed in the left end?
What is the speed of the gas in the left end of the pipe?
