If a large pool of water was rotating the same speed as an amusement ride, how far would the surface of the water rise, between the where the chairs are hanging when the ride stopped- which is 15ft from the center support column, and where the chairs are moving when the ride is operating- which is around 20ft from the center column. From prior experience, you estimate it will take 8 seconds to make a full revolution when the ride is operating.
In summary: Given r1: 15ft; r2: 20ft; w=2pi/8 rad/sec
a) Find: change in z (in feet) between the inner (r1) radius and outer (r2) radius.
b) Is change in z dependent upon the specific weight or density of the fluid?
If the allowable shear stress is 100 MPa, calculate the maximum shear force V that a W460 X 60 structural steel wide flange is capable of resisting. Use the average web shear approach.
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 s..
The relative density of a sloped sand deposit is known to be 75%. Water is observed to be seeped through this slope at a rate such that the discharge velocity is 0.6 m/day. If the hydraulic conductivity for this deposit is 4×10-4 m/s.
Derive an expression for small flow rates over a spillway, in the form of a function including dimensionless quantities. Use dimensional analysis with the following parameters
A 110 f t long, 5 in in diameter (f = 0:033) connects two reservoir whose water surface elevations differ by 12 f t. Compute flow rate in pipe.
With a safety factor of two on the time, determine the maximum static stress the component must sustain in order to have a service life of 10000 hours.
determine the angular acceleration of the spool and the acceleration of the trailer. The wheels have negligible mass and are free to rotate.
Gas is flowing in a long 9-in-diameter pipe from A to B. At sectionA the flow is 0.65 lb/sec while at the same instant at section Bthe flow is 0.72 lb/sec. The distance between A and B is 750 ft.
A conical tube of length 8 m fixed vertically with its smaller end upwards. The velocity head and pressure head at upper ends are 1.27 m and 2.50 m respectively. The velocity head and pressure head at lower ends are 0.203 m and 5.407 m respectivel..
Determine the horizontal spacing of the vertical drains if the drains are installed in triangular grid to reach 90% of primary consolidation in 1.5 years after the commencement of fill placement.
A design for a hovercraft is made. A fan sends air in from the top of the rectangular chamber (60F) and is exhausted between skirts and the ground. Pressure in the chamber is responsible for lift, and the craft is 15 by 7 ft.
A standard five-day BOD test is run using a mix consisting of four parts distilled water and one part wastewater (no seed) the initial DO of the mix is 9.0 mg/l , and the do after Five days, determined to be 1.0mg/l. what is BOD5
