That would depend on the application as some are larger then 48"
Same as you would in inches 3.14159265 and PSI have to be known
Very few heat water internally. These are usually very expensive and showcase the feature. It usually called a 'sterilization cycle'.
Copper is used as hot water pipes because the copper will not corrode when the hot water goes through the pipes
Depends on the system Pumped discharge can be as small as 2" diameter Gravity drainage no smaller then 3" or larger then 4"
yes
Why is the second paragraph a contradiction of the first? If hot water pipes 'Absolutely' do not freeze faster than cold water pipes then why the comment about the cold water pipes having a larger diameter which causes them to freeze at a slower rate than the smaller hot water pipes? Also, the word then in the last line should be thanand there should be an a between usually and larger. And, piping should be changed to pipe.
The water pipes are full of cold water. All that cold water has to be flushed from the pipes before the hot water from the tank reaches your faucet.
Your cold water may be warm due to a variety of reasons, such as a malfunctioning water heater, hot water mixing with cold water in the pipes, or warm weather causing the water in the pipes to heat up.
some times when temperatures go really cold in winters it causes water to freeze and as the water in pipes starts to freeze, the expansion that takes place when water freezes causes pipes to break
Cold for the calcium carbonate is disolved by hot water.
Yes, they can

They are not usually smaller - some amateur plumbed yours.
Generally, hot water pipe diameters are 22mm or 0.866 inches
Diameter.
That depends upon the length and diameter of the pipe connecting to the hot water tank. Also, the greater the distance, the more hot/cold mixing will occur, resulting in even greater water loss. Most copper household plumbing pipe is 1/2" in diameter, and hot water pipes may range from 10' to 80', depending on angles and turns in the plumbing. An 80' pipe will hold about 2 gallons of water. This is water that was heated in the water heater, but upon setting in the pipe gave up all, or most, of its heat to its surroundings.
if it has a ice/water dispenser, then yes. Usually 1/4" diameter poly tubing.
