Holding tube length calculator

To use add your values to the empty fields below
L/h
Internal diameter of holding tube, mm
Mean holding time, seconds
Efficiency factor
   Use 0.5 for laminar flow and 0.82 for turbulent flow. Refer to the Reynolds number - efficiency factor chart below.

Further information on holding tube length and its significance in thermal processing is available in the article on UHT processing.
