1.Air at 70 degrees Celsius and atmospheric pressure flows with a velocity of 22 fps through a 3-in diameter pipe (e=0.00015 in). Find the friction head loss in 75 ft of pipe.

2.Two long pipes convey water between two reservoirs whose water surfaces are at different elevations. One pipe has a diameter twice that of the other; both pipes have the same length and the same value of f. If minor losses are neglected, what is the ratio of the flow rates through the two pipes?

3.With laminar flow in a circular pipe, at what distance from the centerline (in terms of the pipe radius) does the average velocity occur?
