The hot and cold water that we use in our homes is pumped through pipes. Water in a city is distributed by extensive piping net-works. Oil and natural gas are transported hundreds of miles by large pipelines. Blood is carried throughout our bodies by arteries and veins. The cooling water in an engine is transported by hoses to the pipes in the
