Gas flows at a steady rate in a 100-mm diameter pipe that enlarges to a 150- mm diameter pipe. At a certain section of the 100-mm pipe the density of the gas is 200 kg/m³ and the velocity is 20 m/s. At a certain section of the 150- mm pipe the velocity is 14 m/s. Which nearly gives the weight flow rate in N/s in the pipe? O a. 412.5 N/s O b. 125.7 N/s 331.1 N/s O d. 308.2 N/s

Question
Gas flows at a steady rate in a 100-mm diameter pipe that enlarges to a 150-
mm diameter pipe. At a certain section of the 100-mm pipe the density of the
gas is 200 kg/m³ and the velocity is 20 m/s. At a certain section of the 150-
mm pipe the velocity is 14 m/s. Which nearly gives the weight flow rate in N/s
in the pipe?
O a. 412.5 N/s
O b. 125.7 N/s
331.1 N/s
O d. 308.2 N/s
