The density of copper is 559 lb_m/ft^3. What is the mass of the copper pipe in pounds? A copper pipe, used for plumbing from the water main to a house, is 5 meters long and has a circular crosssection 3.2 cm in diameter. There is a 2.4 cm diameter hole in the center of the crosssection for the entire length of the rod.

Best ResponseYou've already chosen the best response.0i think its something like 1lb_m = 2.2 kg/m^3

Best ResponseYou've already chosen the best response.1How many times can you put it into your software? I am going to do it again to double check.

Best ResponseYou've already chosen the best response.1Maybe you should try 1 pound since they gave the density to the nearest pound. Or maybe try two significant digits since that's the number of significant digits in the diameter measurement.

Best ResponseYou've already chosen the best response.1Or maybe three significant digits since the density has 3 significant digits.

Best ResponseYou've already chosen the best response.1Oh gees. The density is given per cubic foot. I have to recalculate.

Best ResponseYou've already chosen the best response.1I found an online volume calculator for pipe. It allows me to put in the diameter in cm the length in m and get the volume in cubic feet. So I put them in, subtracted and got .06213 cubic feet and it came out to 34.73 lbs.

Mertsj

Best ResponseYou've already chosen the best response.1So maybe try 35 pounds or 34.73

Best ResponseYou've already chosen the best response.1Also I found online that the density of copper is 556 pounds per cubic ft. There isn't a typo in the problem is there?
