Helium at 25°C and 110 kPa (absolute) flows into a copper tube (1-1/4-standard, type M) that is 10 m long. Is the flow fully developed at tube end if the helium mass flow rate is 0.02 kg/s?   Ethyl alcohol flows into a 6 cm ID pipe through a well-rounded entrance. After 20 cm of pipe length, measurements taken in the pipe show that the flow is fully developed. Determine the volume flow rate in the pipe, assuming laminar flow exists.
