About Press Copyright Contact us Creators Advertise … NettetThe milk, at pasteurization temperature and under pressure, flows through the holding tube where it is held for at least 16 sec. The maximum velocity is governed by the speed of the timing pump, diameter and length of the holding tube and surface friction. Nettetholding time is calculated by assuming that the maximum velocity is twice the average velocity based on the maximum flow rate. Turbulent flow is assumed where the Reynolds number exceeds 4000. For turbulent flow, the holding time is calculated from the actual measured fastest particle velocity based on the maximum flow rate. the dawg house marion
