Tube 4.00 m

Water 1.00 m C6.3 *C6.4 Suppose you build a house out in the “boonies” where you
need to run a pipe to the nearest water supply, which is fortunately at an elevation of about 1000 m above that of your
house. The pipe will be 6.0 km long (the distance to the water supply), and the gage pressure at the water supply is 1000
kPa. You require a minimum of 3.0 gal/min of water when
the end of your pipe is open to the atmosphere. To minimize
cost, you want to buy the smallest-diameter pipe possible. The
pipe you will use is extremely smooth. (a) Find the total head
loss from the pipe inlet to its exit. Neglect any minor losses
due to valves, elbows, entrance lengths, etc., since the length
is so long here and major losses dominate. Assume the outlet of the pipe is open to the atmosphere. (b) Which is more
important in this problem, the head loss due to elevation difference or the head loss due to pressure drop in the pipe?
(c) Find the minimum required pip...
