1.Water flows at 0.32 m^3/s through a 600-mm-diameter pipeline with a head loss of 0.0029 m/m. Find the value of the Hazen Williams coefficient.
2.Water is pumped from the large tank shown in Figure. The head loss is known to be equal to 5V^2/2g and the pump head is hp = 18 - 4Q^2, where hp is in ft when Q is in ft3/s. Determine the flowrate. Figure is an open tank leading to a horizonal pipe with area .10 ft^2 and height of 13 ft. Find Q.
3.Water leaves a turbine at 18.5 fps and enters a tailrace having an average velocity of 1.5 fps. What is the submerged discharge head loss? By what percentage is this loss reduced if the provision of a draft tube increases the discharge flow area to six times the size?
Find the present worth of a series of investments that starts at $1000 in year 1 and increases by 12% per year for 20 years. Assume the interest rate is 12% per year.
Maximum dry unit weight was found to be 114lb/ft^3 at a water content of 13.5% in labratory tests. Results of a field unit weight test were dry unit weight=111lb/ft^3 and a water content 11%.
The Metrodome's inflatable roof covers 10.0 acres and its interior volume is 60.0x103 cubic feet. During construction, 40.0x103cubic yards of concrete, 11.9x103 tons of reinforcing steel, and 5.00x102 tons of structural steel were utilized.
A municipal water plant has four filters that are each 20 ft long by 15 ft wide by 5 ft deep. The demand for water requires that they only operate, on average, three filters per day at a loading of 3 gallons per min / ft^2.
Due to a street crossing a roadway, the elevation of the roadway at station 3 +413.760 must be at 129.388 m. Design the curve?
A water treatment plant treats a continuous flow rate of 50,000 m^3/day and plans to build a 10,000 m^3 tank to house an additional treatment process. What will be the steady-state effluent concentration of an ideal CSTR
Write a detailed set of instructions (algorithm) for replacing the tire and inner tube on the front wheel of a ten-speed bicycle. The bicycle has caliper brakes that must be loosened unless the tire is not inflated.
A reservoir at elevation 700 ft will supply a second reservoir at elevation 460 ft. The reservoirs are connected by 1300 ft of 24-in cast-iron pipe and 2000 ft of 20-in cast iron pipe in series. What will be the discharge delivered from the upper ..
Determine the magnitude and the point of application the resultant of the four wind forces (distance right of AB, and distance below BC) when a=1.5ft and b=13ft.
A flexure test is done to determine the modulus of rupture of wood. Given that a=15in, L=34in, and the maximum load P that was applied was 5950lbf, what is the modulus of rupture of wood
A 600 MW power plant has an efficiency of 36 percent with 15 percent of the waste heat being released to the atmosphere as stack heat and the other 85 percent taken away in the cooling water.
sled and rider with a total weight of 200 lb travel down smooth slope defined by equation y=x^2/20. At x=40 ft the sled's speed is 10 ft/s. At x=40 ft determine rate of increase of speed and the normal force which the slope exers on the sled.
