In this simulation a channel's cross section was analyzed, 5 NPS 1/8 SCH 40 pipes were used to cool down stationery water in a larger channel, flow was analyzed for 10s (more CPU time for longer calculation on my CPU). <br /> <br />Ambient Temperature: 313.15 K <br />Initial Pipe (all 5 pipes) Temperature: 313.15 K <br />Water Temperature: 281.15 K <br /> <br />Water Flow Rate (Pipes): 0.00015 m^3/s (9 lt./min) <br />Water Flow Rate (Channel): 0 m^3/s <br /> <br />Material of the Pipes: Steel Stainless 302 (Pre-Defined\Alloys) <br />Gravity: On <br /> <br />Coarse Mesh (3/8 Level) <br /> <br />As soon as the flow started, the pipes and water (stationery) started to cool down, as you can see from the temperature graphics attached (all photos are after 10 s of flow). <br /> <br />It will take a large amount of CPU power and time to calculate time for water (stationery) and all the 5 pipes to be at same temperature as cold water.
