Consider a cylindrical cross-section pipe that is 50 m long with a 7 cm diameter, and which has a starting pressure of 320 kPa and an outlet pressure of 105 kPa. A pressure sensor is located 10 m from the start of the pipe.
(a) Calculate the pressure that this sensor would read if the fluid were water (p = 1000 kg/m3).
(b) If the pipe instead contains gaseous carbon dioxide in isothermal flow, would the pressure be the same at this sensor as if the fluid were water?
