Problem 2 (40 pts) Water flows through a horizontal pipe at a rate of 0.0025 m3/s. The pipe consists of two sections of diameters D = 0.18 m and d = 0.06 m with a smooth contracting section. The pressures at the two pipe sections (designated as 1 and 2 in the figure) are measured by pressure gauges. The reading at section 1 gives P1 = 1,000 Pascals. Neglecting frictional effects, determine the following: The average velocities at sections 1 and 2, which are v1 and v2, respectively, in m/s. The value of P2, in Pascals

A. Escuchar unas letras: ¿Cómo se escribe…? Luís and Emma are watching television in Spanish. When Luis doesn’t understand a word, Emma spells it so Luís can write it down in a notebook. First, listen to the spelling of each word. Then, type each letter you hear to reveal the word. Focus on spelling the word. You do not need to recognize or understand its meaning. (¼ pt. per letter—a required accent mark must be present for credit; 8 pts. total) MODELO: (You hear): “a – ere–a” (You type): a r a 1. [1] 2. [2] 3. [3] 4. [4] 5. [5]

A single-story wood-frame building is exposed to a wind load of wU = 385 lb/ft. For simplicity, assume this load was determined from the load combinations, i.e. do not apply the load combinations to it, and that the building has no windows or doors. Let L = 36 ft, b = 20 ft, and the height of the walls be 8 ft. What is the unit shear in the shear walls?

A building with a non-structural interior wall is exposed to a transverse load of w = 375 lb/ft. Assume this load was determined from the load combinations, i.e. do not apply the load combinations to it. What is the roof diaphragm unit shear? Let L = 24 ft, a = 20 ft, b = 4 ft, be = 10 ft, and bi = 3 ft.

A building with a non-structural interior wall and an opening is exposed to a transverse load of w = 205 lb/ft. Assume this load was determined from the load combinations, i.e. do not apply the load combinations to it. What is the collector force at the edge of the opening (point A)? Let L = 44 ft, a = 30 ft, b = 14 ft, be = 30 ft, and bi = 10 ft, bo = 12.5 ft.

Use the AWC Special Design Provisions for Wind and Seismic, 2015 Edition and ASD procedures to answer the following question.A building with a non-structural interior wall is exposed to a transverse load of w = 355 lb/ft. The roof is sheathed with single-layer diagonal lumber sheathing. Is the diaphragm satisfactory in regard to the maximum diaphragm aspect ratio? Let L = 56 ft, a = 40 ft, b = 16 ft, be = 22 ft, and bi = 7 ft.

Use the AWC Special Design Provisions for Wind and Seismic, 2015 Edition and ASD procedures to answer the following question.A building is exposed to a transverse load of wU = 415 lb/ft due to wind. Assume this load was determined from the ASD load combinations, i.e. do not apply the load combinations to it. The wood structural panel is 7/16-in. thick 24/16 span-rated sheathing blocked. Nails are 8d common and spaced every 6 in. at diaphragm boundaries and all panel edges utilizing a single row of nails. Is this design adequate for the transverse load? Let L = 54 ft and b = 30 ft.
