Paper Details

The equation has been proposed by Hausen for the transition range

(2300 < Re < 8000) as well as for higher Reynolds numbers. Compare the values of Nu predicated by Hausen?s equation for Re = 3000 and Re = 20,000 at D/L = 0.1 and 0.01 with those obtained from appropriate equations or charts in the text. Assume the fluid is water at 15°C flowing through a pipe at 100°C.
GIVEN
Water flowing through a pipe
The Hausen correlation given above
Water temperature = 15°C
Pipe temperature = 100°C
ASSUMPTIONS
Steady state
Constant and uniform pipetemperature
