Wouldn't that depend on the Diameter?
Pi x R sq x LENGTH would give you the exact answer(Pi = 3.14159265)
Your answer is nothing more than smartmouth as the diameter is already given above in the question for those who can be bothered to read.
A foot long tube, six inches in diameter.
So the calculation for the person asking the question is:
12 inches x pi (3.142) x radius (3) squared.
= 339.12 cubic inches
I work in a chemistry lab, typically, dangerous chemicals are marked with a red, yellow, or orange label. Hazardous is usually marked with an orange label.
The simplest answer is that the electric utility uses a transformer across 2 of the 3 hot leads to develop a single hot lead with an earth reference. What follows below is frequently edited by both amateurs and professionals, with mixed results. Wikipedia is a better source of more detailed information on this subject, in part because the article on three phase power has pictures.
It acts as an abrasive.
Thermostat may be stuck open or heater core clogged. Do a complete cooling system flush and replace the thermostat with an OEM thermostat. After draining and flushing with the heater in the hot position, pour in a 50/50 mix of antifreeze and distilled water. Now bleed all air from the system with the bleeder valves. If it has none, jack up the front of the car as high as possible, remove the radiator cap, (engine cold), and fill the system to the top. Start the engine and run until all air bubbles stop escaping. Keep it topped off while doing this.
