Air flows steadily between two sections in a long, straight portion of 4 in. inside diameter pipe (D1=D2). The uniformly distributed temperature and pressure at each section are p1=100psia, p2=18.4psia, T1=540 R and T2=453 R. The average velocity air velocity (nonuniform velocity distribution) at section 2 is 1000ft/s (V2=1000ft/s). A) Calculate the density of air flow ate sections 1 and 2. B) calculate the mass flux through section 1.
An open rectangular channel is 50 feet wide, flowing at a depth of 5 feet, and is carrying 1000 cubic feet per second. What is the maximum step height than can be placed into the flow without disturbing the upstream depth, without acting as a chok..
A 300 mm diameter pipe is placed in a 3 m deep rectangular trench that is 0.60 m wide. The trench is backfilled with clay that has a bulk unit weight of 18.8 kN/m3. Compute the dead load due to backfill that the pipe must support.
Many years ago, well-known architect Frank Lloyd Wright designed a mile-high skyscraper, which has never been built.
A 1.5 m diameter culver (concrete barrel, well - rounded entrance) that is 20m long is installed on a slope of 2 percent. The design discharge is 9.5 m^3/sec and the inlet will be submerged but not the outlet.
