Everyone has experienced using a water fountain that produces a bit too much water pressure. In fact, the drinking fountain on the 3rd floor of Dana Hall at the south end of the hallway shoots a pretty good jet of water. Using a water bottle with a known volume (such as a typical 1-liter Nalgene bottle), a) determine the volume flow rate for this particular water fountain. Make additional physical measurements on the water fountain to estimate: b) the water velocity, and c) the pressure at the exit nozzle.
Oxygen flows without a gain or loss of heat through a horizontal pipe of constant cross section. At section 1 the pressure 175 psia, the velocity is 78 fps, and the temperature is 50°F; at section 2 the pressure is 130 psia
he base-10 logs of the annual peak discharges in cfs for WY 1965-2010 have a mean of 3.678 and a standard deviation of 0.456. Assume that the probability distribution of the annual peak discharges is log-normal
The Pomdeterra wastewater treatment plant produces thickened sludge that has a suspended solids concentration of 3.8 percent. They are investigating a filter press that will yield a solids concentration of 24 percent.

The house has a dirt-floor crawl spaces (1m high). The emission rate of radon into the crawl space is 0.6 pCi/m^2-s. An exhaust system was added to provide 1 air exchange per hour (ACH) in the crawl space
The flywheel rotates with an angular velocity of omega = (4*theta^(1/2)) , where theta is in radians. Determine the time it takes to achieve an angular velocity of omega = 190 rad/s . When t = 0, theta = 1 rad .
An earth retaining structure is 12 feet high. The soil behind the earth retaining structure is a sand having a moist unit weight equal to 125 pcf, a saturated unit weight equal to 130 pcf, and a friction angle equal to 32 degrees.
A pipe network in the form of a cube is made with twelve identical pipes. Each pipe forms an edge of the cube. If the entire inflow and outflow occurs at two adjacent corners, determine the percentage of the flow
The plant will be designed with a rapid mix unit followed by flocculation and sedimentation basin. The water source has an average winter water temperature of 40 and an average summer water temperature of 70oF.
Find an equation that expresses the relationship between the wages earned (x) and the Social Security taxes paid (y) by an employee who earns less than the maximum taxable wage base.
A cylinder fitted with a frictionless piston contains 2 kg of superheated refrigerant R-134a vapor at 350 kPa, 100oC. The cylinder is now cooled so that the R-134a remains at constant pressure un- til it reaches a quality of 75%.
How do you determine the cross-sectional area of the concrete and steel and the stresses in each if the column deforms .01 inch while carrying 100 K load? The cross sectional area is 15 inch and column height is 10 feet.
