The flow depth and velocity before the jumo are 0.8 m and 7 m/s respectively. The flow depth and velocity after the jump are 2.46 m and 2.28 m/s respectivly. Assuming a flat channel, determine a) th
A rectangular channel has water flowing at a depth of 1.6 ft with a corresponding specific energy of 1.736 ft. A step up on the channel bed resulte in the flow becoming critical. The critical depth
Suppose an expert hypothesizes that the probability of a rainfall event causing a particular stormwater retention pond to overtop can be modeled with a beta (a, B ) distribution. Over n years of dat
A cylindrical tank with inside diameter of 300mm and wall thickness of 5mm is subjected to an internal pressure of 2Mpa. The tensile stress in mpa in the wall of the tank is mostly near
Determine the axial and hoop stresses at the lower end of the vessel. A standpipe 12 ft in diameter and 50 ft tall is being con- structed for use as a storage tank for water with a specific weight of
The maximum flow rate of a standard shower head is about 3.5 gpm and can be reduced to 2.75 gpm by switching to a low-flow shower head that is equipped with flow controllers. Consider a fam- ily of
An 8.5 m compacted fill is to be placed over the soil profile. Consolidation tests on samples from points A and B produced the following results. a) Calculate the consolidation settlement caused by
The company can either buy a single 200m^3 ideal plug flow tank, or three 80m^3 completely mixed tanks that operate in series. the cost is essentially the same. The pollutant is removed as a part of
Find the discharge flowing over a rectangular sharp crested wire, in GPM, which has a width of 9.9 feet and a discharge coefficient of 3.24, if the head above the crest is 1.74 feet.
The defender had a first cost of $300,000, but its market value now is only $100,000. It has chargeable expenses of $120,000 per year and no expected salvage value. To simplify calculations, assume
A stream of Refrigerant-134a at 1 MPa and 12 C is mixed with another stream at 1 MPa and 60 C. If the mass flow rate of the cold stream is twice that of the hot one, determine the specific volume of

the 15,000 kg boxcar A is coasting freely at 1.5 m/s on the horizontal track when it encounters a tank car B having a mass of 12,000 kg and coasting at 0.75 m/s toward it. If the cars meet and coupl
Determine the strain components strainx, Strainy, and gammaxy, then sketch the deformed shape in the xy orientation, paying particular attention to the sign of the shear deformation.
According to a settlement analysis, the weight of this fill will cause 600 mm of the total settlement over a period of 30 years. The differential settlement will probably be about 100mm. Although th
One issue is to calculate the "pooled" variance and "pooled" standard deviation. Since we expect that the variances of the improvement scores by both groups could be a bit different, we'd want an ov
