Unformatted text preview: I 222. 223. 224. 225. 226. 227. If the AP; per foot is 0.007 PSI; the total friction loss in the piping is: _________ PSI. In the energy-balance equation, the static head, velocity head, and potential head are all expressed in units of of the fluid flowing. Suppose the specific gravity of the liquid is 0.8. Friction is 4.9 PSI. Head = i.— 0.433 x sp. gr. The friction head in feet of this liquid is: about _____ feet. If the total head at the inlet is 20 feet, the total head at the outlet will be ____ feet (assuming no heat loss or work added or lost). The friction head in piping, then, is: the __ per foot of pipe; times the actual __ of the pipe added to the _ length for fittings; converted to units of __ of the liquid flowing. For minimum friction head, piping should: have as __ an interior wall as possible; have as (many/few) valves and fittings as possible; be free of sudden changes that would lead to enlargement and —__ losses; and be _—_ of scale and other foreign deposits. 27 4.9 feet 14 AP{ length equivalent feet, or head smooth few contraction clear, or clean, or free ...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
