Consider a small town in the Phillippines, where the average weight of people is 55 kg, and the average lifespan is 60 years. The people here eat lots of fish due to abundant availability from the l
If the energy loss in the contraction is equal to \(V_1^{2}/2g\) where V1 is the average velocity upstream of the contraction, what is the depth of flow in the constriction. A lined rectangular c
A W14x68 section of A992, Grade 50 steel, is used as a steel column with a total unbraced height of 12 ft. The column ends are both fixed. Determine the maximum axial LRFD safe load for this column
A steel column has a total unbraced height of 14 ft and carries an axial LRFD load of 950 kips. The column ends are fixed. Select an economical HSS 14x14 for this column.
The beam is loaded with a concentrated live load of 10 kips at the center of its span, in addition to its own weight.. The dead load includes the beam weight. The steel is A242, Grade 50.
A simply supported steel beam over a 24-ft span carries a uniformly distributed dead load of 2 k/ft, including an allowance for the self-weight, and a live load of 3.5 k/ft. The steel is A992, Grade
During a BOD test, 2 mL of waste water having a DO of 0 was mixed with 298 mL of dilution water having a DO of 8.9 mg/L. After 5 days and 20 days, it was noted that the DO of the test bottle was 4.0
