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.
