1.A spherical pressurevessel of 1.2m outside diameter is to be fabricated from a steelhaving an ultimate stress of σU450 MPa. Knowing that a factor of safetyof 4.0 is desired and that the gage pressure may reach 3 MPa,determine the smallest wall thickness which may be used.
2.Determine the normal stress in a basketball of 12 inches diameter and 0.1 inch wall thickness which has been inflated to a gage pressure of 15psi.
A city of 60,000 people generates 50,000 tons of MSW per year. At current recovery and recycling rates, 21 percent of that MSW is recovered or recycled and the rest goes to a landfill.
Argon is expanded in an isentropic turbine from 2 MPa and 500oC to 200 kPa. Determine the outlet temperature and the work produced by this turbine per unit mass of argon.
The vertical cross-section of the trough parallel to an end is shaped like the graph of y=x6 from x=-1 to x=1 . The trough is full of water. Find the amount of work in foot-pounds required to empty the trough by pumping the water over the top.
Determine the discharge of a trapezoidal concrete channel section with a bottom width of 4 ft and side slopes of 2:1. The depth of flow is 5 ft and the channel slope is 0.5%
You and your friend go into sports bar where a dart throwing competition is going on.you buy m darts at 1 dollar each.you throw these m darts at the board.Of these, N darts hit within the inner circle.
A municipal WWTP discharges 22.5 MGD of secondary effluent containing 45 mg/L of ultimate BOD at 26.7 C with 1.3 mg/L of dissovled oxygen. The stream flow is 237 ft^3/s at an average velocity of 2.1 ft/s and an average depth of 7ft.
In a water table aquifer bounded on the ends by rivers, the hydraulic conductivity is 50 m/day. The hydraulic heads at x = 0 and x = 1000 m are 100 m and 90 m, respectively.
An agronomist wants to measure the rainfall at the centroid of a plowed field between two roads. What are the coordinates of the point where the rain gauge should be placed?
The two outer bars (material A) are identical. The cross- sectional area of the middle bar (material B) is 31.544% larger than the cross- sectional area of one of the outer bars. Also, the modulus of elasticity of material A is twice that of mater..
A sewage treatment works (STW) with 4 single-stage trickling filters has become organically overloaded due to the discharge of a biodegradable industrial effluent to the STW. This is causing effluent to pond on the surface of the filters.
Find the correction for the calibration of the measuring tape using its formula. During the calibration of the measuring tape on comparator of 100.000m the length of the tape turned out to be of 99.993m
Water at 20 degrees flows at a velocity of (V =) 2 m/s in a (D =) 250-mm diameter horizontal ductile iron pipe. Estimate the friction factor f in the pipe, and state whether the pipe is hydraulically smooth or rough.
