What would be the approximate volume of air ( if any) flowing OUT of the 4 inch pipe and into the house over the course of one hour if the outside air temperature was 90 degrees Fahrenheit ( 32C )?
At a depth of approximately 10 feet (3 meters) below the surface of the earth here the temperature is about 72 degrees Fahrenheit ( 22 C) year round. (Goswami and Biseli 1993). 4" PVC pipe extends 400 feet below grade. Inside 4" pipe is 2" PVC pipe filled with 72 degree water.
4" pipe enter house and is vented through roof 15 feet above grade.
2" pipe provides water to plumbing fixtures in house.
4" pipe is also vented inside house 1 foot above grade.
How much cool air would flow from this open 4" pipe without using any mechanical means to move air? Sketchup Model (requires Sketchup software to to be installed) https://docs.google....QU9ScTM1Q05KMlE Images from model
