A rectangular channel of width 12 ft has an upstream slope of 0.02 ft/ft and a downstream slope of 0.0005 ft/ft. Both reaches have lengths of 500 ft. The upstream reach has a Manning's roughness of 0.016 and the downstream reach has a roughness of 0.011. The design discharge is Q = 460 cfs, the low discharge is Q = 230 cfs, and the flood discharge is Q = 690 cfs. Using the direct step method by hand with 1 step, determine the location of the hydraulic jump relative to the slope break for the design discharge. Classify the jump type and calculate the energy lost.
List the series of steps involved in converting rural land into development. You may refer to an example of local conditions in your reference jurisdiction or you may use a description of such steps that you find from other sources
Water is at 9000 kPa and 300 degrees celcius and flows through a partially open valve. Pressure immediately after the valve is measured to be 600 kPa. Calculate the specific internal energy of the water leaving the valve. Neglect kinetic energy ch..
A bar 25in long attached to one wall was heated by 100 degress F. There is a .5 in gap between the bar and the other wall. The area of the bar is .5 in^2.The coefficient for expansion is .0004/F and the modulus of elasticity is 230 ksi. Find the fina..
Estimate the power needed to overcome the aerodynamic drag of a person who runs at a rate of 100 yds in 10 s in still air. repeat the calculations if the race is run into a 20-mph headwind: a 20-mph tail wind.
a) The maximum flow rate that can be achieved without cavitation occurring in the piping system. b) The maximum elevation of the highest point of the piping system to avoid cavitation.
The number of teleport inquires x in a time sharing system average .2 millisecond and follows a Poisson distribution. Find the probability at least one inquiry is made during the next millisecond.
Water occupies the bottom 0.8 m of a cylindrical tank.On top of the water is 0.3 m of kerosene, which is open to the atmosphere. If the temperature is 20 degrees C, what is the gage pressureat the bottom of the tank
The shape below has a cut along the entire length of the member thus making it an open section. The uniform thickness is 0.125in. Determine the maximum shear stress for the shape. Compare the stress for this open shape to a shape without a cut.
Water flows in a river. At 8 a.m. the flow past bridge 1 is 2150cfs. At the same instant the flow past bridge 2 is 1800 cfs. At what rate is water being stored in the river between the two bridges at this instant? Assume zero seepage and negligible e..
you fill a 2-cubic wheelbarrow to the top with aggregate. if the specific gravity of the aggregate is 2.548, and 18% of the aggregate is void spaces, how much does the aggregate in the wheelbarrow weight
Create a depreciation schedule showing annual depreciation amounts and end-of-year book values for a $26,000 asset with a 5 year service life and a $5000 salvage value, using the MACRS depreciation method.
