Water at 20 degrees centrigrade in a 85 degree reducing bendis used in what is otherwise a continuous pipe. The systemoperating is 0.10 cubic meters per seconds. The bend isin thehorizontl pane and its weight is supported from below. The reducingbend is attached at its inlet and outlet with bolted flangefittings. The inlet diameter is 20 centimeters. The outlet diameteris 10 centimeters. Gage pressure at the 20 centimeter inlet is220KPa.
Find the component forces that the flange bolts must resist.Use an analysis that does not include friction losses asthe water passes through the reducing bend.
The pipe has an outside diameter of 60mm and an inside diameter of 50mm. Find the torsional moment T if the maxiumum shear stress is 80MPa.
Transportation network, A power generator at a dam can send 300 megawatts to substation 1, can send 200 megawatts to substation 2, and can send 250 megawatts to substation 2
A freeway has a capacity of 4500 veh/hr. A traffic accident occurs at 9AM and the freeway is closed. At 9:15 AM, the freeway is partially opened with capacity of 1500 veh/hr. Freeway is restored to full capacity 4500 veh/hr at 9:30 am.
The maximum eight-hour average concentration of carbon monoxide (CO) in an urban area is measured to be 17 ppm. The NAAQS is 9 ppmv (equivalent to 10.3 mg/m^3 estimated at P = 1 atm and T=298.25°K).
A reinforced concrete beam having the cross section shown is on a simple span of 28ft. It carries uniform service loads of 3.60 kips/ft live load and 2.20 kips/ft dead load. Check the adequacy of the beam with respect to the moment.
You may pay $15,000 for an annuity that pays $2500 per year for the next 10 years . You want a real rate of return of 5% , and you estimated inflation will average 6% per year.
Knowing that these forces are equivalent to a force-couple system at C consisting of the force C= (- 8 N)i+ (4 N)k and the couple Mc =(360 N ⋅ m)i, determine the forces applied at A and B when Az = 2 N.
In oder to erect a perpendicular to a line bythe method inducate in figure the distance bc is equal to 40 ft. when the zero mark of a 100-ft tape is held a point B and
What will the freeway's density and level of service be before and after the ban? (Assume that the trucks are removed and all other traffic attributes are unchanged).
At that time, there is no more fuel in the rocket engine and the rocket continues upwards in free fall (g=0 ft/sec/sec). (a) How high will the rocket reach before it begins to fall back to the campus
a. Determine the shear and moment diagram. b. Calculate the maximum normal stress on the top of the beam, on the bottom of the beam and indicate in terms of x its location.
