Develop a preliminary WBS for a small one-story commercial building to be constructed. It is 30 by 60 feet in plan. The exterior and interior walls are of concrete block. The roof is constructed of bar joists covered with a steel roof deck, rigid insulation, and built-up roofing. The ceiling is suspended acoustical tile. The floor is a concrete slab on grade with an asphalt tile finish. Interior finish on all walls is paint.
Runoff from a storm flows into a reservoir with a surface area of 20.0 ha at a constant rate. The reservoir level is observed to rise at 1 mm per minute when water is being released through the dam at a rate of 10 m3 per second.
Thin rubber strips are used to provide increasing resistance to orthopedic patients during large motion exercises. The sheets shown are 0.03125 in thick and 3 in. wide. Say the rubber properties are 120 psi and v= 0.47.
A steel plate 5/16" thick is embedded in a horizontal concrete slab and is used to anchor a high-strength cable as shown. The diameter of the hole in the plate is 3/4", the ultimate strength of the steel used is 36 ksi
It is required to dewater a construction site 80 m by 80 m. The bottom of the construction will be 1.5 m below the initial water surface elevation of 90 m. Four pumps are to be used in 0.5-m diameter wells at the four corners of the site.
A permeation membrane separates an inlet air stream (79 mol% N2, 21 mol% O2) into a permeate stream and a reject stream. The inlet stream conditions are 293K, 0.5 MPa and 2 mol/min; the conditions for both outlet streams are 293 K and 0.1 MPa.
Discharge from an orifice of 75mm diameter is 0.02 m^3/s under a constant head of 3 m. An external mouthpiece of the same diameter is installed that raises the coefficient of contraction from 0.63 to 1.0.
Assuming that silt is equivalent to a liquid having a density of 1760 kg/m3, determine the overturning moment of silt and water about point A.
Find the magnitude and direction of the force the cable exerts on the pin for the pulleys
Zwango Plus Manufacturing experts that fixed costs of keeping its Zephyr Hills Plant operating will be $1.4M this year. If the fixed costs increase by $100,000 each year, what is the EUAC for a 10-year period Assume the interest rate is 12%.
Determine the maximum displacement of the plate A if the billet strikes the plate with a speed of 8 . Neglect the mass of the springs, rollers and the plates A and B. Take = 4000 , = 40000 .
The number of hours on each machine required to produce a product is given in the following table, along with the number of hours available per week on each type of machine. Assume that the company can sell everything it produces.
If the elevation difference between the water surfaces is y = 25 + x/11 metres, what minimum pipeline diameter will be required to convey the design discharge? Once your design is complete, determine the actual discharge. The value of x equals 23.
