Question
Saturated liquid ammonia is entering a 50 cm diameter 10-m long pipe at a steady 0.1 kg/s mass flow rate
and a mean temperature of 0°C. It is exiting the pipe as saturated vapor at a mean temperature of 0°C.
(a) What is the Reynolds number and flow regime at the beginning and at the end of the pipe?
(b) If the surface temperature of the pipe can be assumed to be constant at 15°C in this section, what
is the average convection coefficient of the ammonia flow?
(a) 1343; 27075
(b) 553.6 W/m2K
