Water flows at Q=10m^3/s in a rectangular channel of width Bw=5.5m. The slope of the channel So=.15% and the Manning n=.038. Estimate the depth y2=100m upstream of a section where the flow depth y1=2.2m Using a) the direct integration method and b) the standard step method. Approximately how far upstream of this section would you expect to find uniform flow?
Compare the total reactor volume required for 90% removal of the same pollutant in a CSTR system that contains a single reactor against a system that contains three CSTR reactors of equal volume in series.
A bridge has cylindrical piers 1 m in diameter and spaced 15 m apart. Downstream of the bridge where the flow disturbance from the piers is no longer present, the flow depth is 2.9 m and the mean velocity is 2.5 m/s.
Calculate the average velocity (rnps), crosssectional area (rn"), and depth (m) for the stretch. To make these estimates, assume that the stretch can be idealized as a rectangular channel.
Find the time for one complete cycle of this motion if the spring constant is 21 N/m. (Assume that once the pendulum ball hits the spring there is no effect due to the vertical movement of the ball.)
determine the velocity and acceleration of point C of the belt, (a) immediately before the power is turned off. (b) 9 s later.
write computer code using Matlab that emoloyes the nelder and mead simplex method to solve the welded-beam design (benchmark problem
What uniform annual series of cash flows over a 12-year period is equivalent to an investment of $5,000 at t= 0, followed by receipts of $600 per year for 11 years and a final receipt of $1,600 at t= 12 of the investor's time value of money is 6% ..
A fluid flowing in a pipe 30cm in diameter has a uniform velocity of 4m/s. The pressure at the center of the pipe is 40KPa, and the elevation of the pipe's centerline above an assumed datum is 4.5m. Compute the total energy per unit weight of the ..
Draw the Bending Moment and Shear Force diagrams for the girder and calculate the maximum tension in the cable.

Determine the mass flowrate through boiler needed to produce 5000KW of power.
A sample with a measured background level (Bi) of 22 mg/l was spiked with the equivalent of 30 mg/l without appreciably changing the sample volume. The result for the spiked sample (Ai) was 49.2 mg/l. Calculate Pi and determine if it falls with th..
