What law of physics determines that an expansion tank (including all other components in between) 8 inches from a source of expansion (ie water heater) in a closed system and an expansion tank (including all other components in between) 8 feet from a source of expansion in a identical but separate system would be subjected to the same amount of pressure from thermal expansion?
For this theoretical closed system we have Type M copper pipe with CTS fittings in a single family residential home with 1 kitchen and 1 bath.
All pipe is no greater than 1 inch in size nor less than 1/2 in size.
An integrated pressure reducer check valve backflow prevention device is installed at the water meter to prevent cross-connection.
Pressure is factory set at 50 psi
Expansion tank pre-charge is statically balanced.
Water heater consists of a standard efficiency 30 gallon glass lined tank and lp gas as a fuel source.
The temperature of the water heater is set to 120 degrees Fahrenheit.
There are zero fixtures in use and the potable system does not provide water to any home heating system.
The outdoor temperature is 75 degrees Fahrenheit
The ambient indoor temperature is 23 degrees Celsius.
The 2 systems are identical except for the location of the expansion tank.
