A hydraulic jump forms in a horizontal trapezoidal channel. The base width is 4m and the side slopes are 45o. The depths upstream and downstream of the jump are 1m and 3m.
(a) Determine the discharge in the channel.
(b) Determine the energy dissipated in the jump.
A bag of potatoes is sitting on the chair. The force exerted by the potatoes on the frame at one side of the chair is equivalent to horizontal and vertical forces of 24 N and 84 N, respectively, at E and a force of 28 N perpendicular to member BH ..
Imagine two small towns of 1,000 people: Blacktop and Parktown. In the urban sprawl that is Blacktop, all the residents own fuel-efficient cars (15 km/liter) and travel an average of 20,000 km per year.
Estimate the chronic daily intake of 1,1,1-trichloro ethane from exposure to a city water supply that contains a 1,1,1-trichloroethane concentration equal to the drinking water standard of 0.2 mg/L.
The theodolite's optical center is 4.66 ft above the upper baseline station at 110+71.25. a) What is the stationing chainage of the lower station
The buses are run by independent drivers, however, who make no attempt to coordinate their schedules. Actually, one bus runs slightly faster than the other so that over many trips the fraction of trips that the second bus leaves within a time t
A rectangular channel 2.0 m wide carrying a discharge of 2.5 m3/s is to be fitted with a weir at its downstream end to provide a means of flow measurement as well as to cause heading-up of the water surface.
A tensiometer is used to measure a compacted soil in the field that has a matric suction of 200 kPa under atmospheric conditions. The pore-water pressure measurement in the tensiometer reaches -99 kPa
150,000 mol of aqueous phosphoric acid (H3PO4) solution contains 5.00% H3PO4 by moles. The solution is concentrated by adding pure H3PO4 at a rate of 20.0 L/min.
Assume the only products are CO2, H2O, CO and N2. State results as the CO molar fraction of both wet and dry exhaust products ( wet exhaust products include H2) and dry exhaust products exclude it).
The only work interaction between the system and the surroundings is via the paddle wheel. The work done on the system via the paddle wheel is 220 ft*Ibf and the heat interaction can be assumed negligible.
Given a sand with a moisture content of 10%, how much water needs to be added to bring the sand to a moisture content of 20%
Under the right conditions, it is possible, due to surface tension, to have metal objects float on water. Consider placing a short length of a small diameter steel (sp. wt. =460 lb/ft^3) rod on a surface of water.
