You are the Chief Engineer for a prominent hydraulics consulting company. Your client wants to pay you lots of money to design a system to deliver 1 m3/s from reservoir A at elevation 300 m to reservoir B at 500 m. The distance from A to B is 1000 km and the elevation between the two reservoirs is given by z (m) = 300 + 1.2x - 0.001x2, where x is the distance from A in km. The system is to consist of a pipeline and a series of pumps. Commercial steel pipe with a roughness e = 0.05 cm and a pressure rating of 150 m head is available. The total cost of purchasing pipe and constructing a pipeline is listed below for various pipe sizes. Pumps that can deliver 1 m3/s at 100 m head cost $10,000,000 each (installed). Determine the most economical design (i.e. pipe size and number and location of pumps). Hint: Vary your pipe diameter and consider pumps in series. Pipe diameter (m) Total Cost ($/km) 0.9 80,000 1.0 100,000 1.1 120,000 1.2 150,000 1.4 200,000 Note 1: Theoretically, a pipeline may be designed to allow pressure to fall to the vapour pressure. In practice, however, water usually contains dissolved gasses that will vapourize well before the vapour pressure point is reached. Such gasses dissolve very slowly. They can move with the water in the form of large bubbles that disrupt the flow. Therefore, negative pressures shouldn't be allowed to exceed about 70% of atmospheric pressure - use this figure in your design calculations. Note 2: The pressure rating of a pipe is the maximum pressure that it can withstand.
Iron can exist in the FCC or BCC structure. For FCC iron, the crystal lattice parameter is a=0.3515nm and the atomic packing factor is 0.74. In an FCC structure, iron atoms have an atomic radius of 0.1263nm.
Two carts with masses of 4.72 kg and 2.84 kg move toward each other on a frictionless track with speeds of 4.86 m/s and 3.97 m/s respectively. The carts stick together after colliding head-on. Find the final speed.
0.5 m-diameter concrete pipe (5.0 cm rigid wall thickness with rigid pipe walls) carries water 600m before discharging into another reservoir. The surface elevation of the downstream reservoir is 55 m lower than the supply reservoir.
A lagoon with a volume of 1200 m^3 has been receiving a steady flow of a conservative waste at a rate of 100m^3/day for a long enough time to assume that steady-state conditions apply. The waste entering the lagoon has a concentration of 10mg/L.
Calculate the time average F of the total force tangent to the toad exerted on the tires during the 8 s. Treat the car as a particle and neglect air resistance.
Labor of this activity is given as in the CREW, 1 brick mason and 1 helper. The productivity is 0.5 labor hours per 1 sf. The wages are for the mason $60 and for the helper $45 per hour.
how many cubic feet of seawater, density 60 lb/ft^3, must be processed to recover 1 ton of magnesium, 1,272 ppm?
The forces acting on the sailplane are represented by three vectors. The lift L and drag D are perpendicular. The magnitude of the weight W is 500 lb. If the magnitude of the resultant of the three forces is 0
A pipeline terminates in a nozzle of outlet diameter = 0.15 m. The free jet from the nozzle is deflected through 120º by a vane as shown. Water flow rate through this pipe is 0.25 m3/s. Ignoring friction, find the force exerted by the jet on ..
Two links AB and B, each 25 in. long are connected at B and guided by hydraulic cylinders attached at A and D. Knowing that D is stationary and that the velocity of A is 30 in./s to the ight
Compacted one cylinder of the soil describes above problem 1 to compare the new results with shown above. The data obtained included a water content of 32.5% and a total density of 121.9 pcf. Comment on these new findings.
If the maximum (total) depth of water that can be accommodated at the weir is 1m and the width of the channel is 4m, determine the crest height of a suppressed weir that should be used to measure the flowrate.
