A person purchases a $5000, 5% per year bond, with interest payable semiannually. The bond has a maturity date of 10 years from now. How much the person must sell the bond for 6 years from now in order to make a rate of return of 10% per year, compounded semiannually is closest.
An obstruction is lodged in a 10-ft wide rectangular channel (n = 0.022) that has a botom slope of 0.005. The depth of the channel just upstream of the obstruction is 5.0 ft. If the flow rate is 325 cfs, what is the channel and flow classification
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
Ball A is thrown vertically upward from the top of a 30-m-high building with an initial velocity of 5 m/s. At the same instant another ball B is thrown upward from the ground with an initial velocity of 20 m/s. Determine the height from the ground..
For the data given below, derive the 2-hr unit hydrograph for a watershed having a drainagearea of 216 km^2, assuming a constant baseflow of 20 m^3/s.
If the elevation of the pipeline at the treatment plant is 125 m, estimate the pressure in the pipeline 1 km downstream where the elevation if 110 m. Hint: Use the Colebrook equation to estimate f, and the energy equation to estimate P2 .
a whirlpool is modeled as the combination of a free and a forced vortex. the maximum velocity in the whirlpool is 10 m/s, and the radius at the juncture of the free and the forced vortex is 10m.
It is desirable to produce a copper-nickel alloy that has a minimum noncold-worked tensile strength of 390 Mpa and a ductility of at least 40% elongation. Is such an alloy possible If so, what must be its composition
an ideal regenerative rankine cycle operates so the steam enters the turbine at 40 bars and 500c and exhausts at 0.1 bar steam at 7 bars is extracted and is used in a single open feed-water heater
Develop algorithms for the explicit solution of the Kinematic Equations when applied to a problem of runoff from a plane surface subject to a steady rate of rainfall excess.
Given that uniform flow is subcrital and there is a weir in a rectangular channel, how do you determine what the weir height should be to force the flow to be critical. Draw this transition on a specific energy curve.
An equal-tangent crest vertical curve has a 50 mi/h design speed. The initial grade is +3%. The high point is at station 33+37.43 and the PVT is at station 37+18.26. What is the elevation difference between the high point and the PVT?
At the minimum volume reached during shrinkage, a specimen of soil has a void ratio of 0.87. if Gs = 2.72, calculate the shrinkage limit
