Air vents
« on: April 04, 2017, 10:37:58 PM »

 Will I need to put air vent risers on the downhill feed pipe to the turbine to prevent air locks ?

Vent risers are only needed where there is not a constant fall in the pipeline. Even a small slope is enough to stop air bubbles becoming an air pocket. Yet even a small high point in the line will usually form an air pocket and so reduce the flow. The temperature and velocity of the flow does have effect on the likelihood of air pockets/locks forming, but the safest design is to have some fall all the way.

 Interesting info. I do have a flat spot even though the slope is more than sufficient. I will prop that up and see what happens.

 Thanks for the info.
