![[5 points] Consider a sand grain 0.8 mm in diameter, what is the flow depth necessary to suspend this grain in a flow with bed slope S-0.001? Use the graph below to determine the settling velocity (ws) of the grain. Use the equations below to complete the question. REMEMBER TO CHANGE ALL QUANTITIES INTO LIKE UNITS (m, s, kg, etc.) BEFORE COMBINING. 1000 100 10 0.1 10 Grain Diameter (mm) ? is basal shear stress. f) is fluid density (water). U is flow velocity, u. is shear velocity.](http://img.homeworklib.com/questions/bfb31c40-5743-11eb-a63f-772899b2c512.png?x-oss-process=image/resize,w_560)

3. (15 points) Consider a filter sand with a diameter of 0.5 mm. Demonstrate that an initial guess for the settling velocity of 0.08 m/s results in the correct value of velocity. Use the following equations for the demonstration. The density of the sand and water are 2650 kg/m' and 999.8 kg/m°, respectively. The viscosity of water is 1.31x10-N-sec/m². 1m=1000mm 4gd(pp-p) 24 Re= Ср +0.34 3CDP Re Re pud 3 V = = + u

2.2 A 250 mm diameter pipe is 1500 m long. When the discharge is 0.095 m3/s in this pipe, the pressure drop between the ends of the pipe is measured as 98.06 kPa. The elevation at the end of the pipe is 10 m below its beginning. What type of flow is this? What is the equivalent sand-grain roughness of the pipe wall? What is the Hazen-Williams roughness coefficient? How much energy is dissipated by fluid friction during each hour...

A laboratory column experiment is set up to test the transport of oil spilled in a sandy aquifer. The test column, 5 cm in diameter and 0.75 m in length, is packed with sand having a median grain diameter of approximately 0.5 mm and porosity of 0.27. The sand was taken from a natural river bed; therefore, microbes-related biological process is expected to present. A mixture of feed solution containing conservative Cl and a surrogate biodegradable hydrocarbon is continuously pumped...

Q2) A canal of trapezoidal section has bed width of 8 m and bed slope of 1 in 4000. If the depth of flow is 2.4 m and side slopes of the chamel are 1 horizontal to 3 vertical, determine the average flow velocity and the discharge carried by the channel. Also compute the average shear stress at the channel boundary. Take value of Chezy's constant = 55. Q3) 6.11. A power canal of trapezoidal section has to be excavated...
