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.
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
The bar under the applied force is now 2.448 meters long. Calculate the following for the bar: a) engineering stress, b) engineering strain, c) true strain, d) Young's modulus, e) What additional information would you need to calculate the true st..
determine a) the x, y,z components of that force b) values of angle thetax, thetay, theta z defining the direction of the recoil force. (assume that the x, y, and z axes are directed respectively east, up, and south)
If all trucks travel at a speed v', cars at a speed v, and the fraction of vehicles passing a stationary observer that are trucks is p, what fraction of vehicles would be trucks on a photograph
A sprinkler system uses an outdoor reservoir at El 50. A fire pump moves Q = 3 ft^3/sec through a 1.0' dia pipe 300' long to an 8" dia main at El 200. To distribute water to sprinklers, a pressure head at the pipe junction hp =100' is required.
Soda Ash and QuickLime, A lime-soda softening plant treats a flow of 150 MGD, and the water has 86mg/l Ca2+, 35 mg/L Mg2+, 299 mg/L HCO3- and 6mg/l CO2.
The 75 lb block is released from rest 5 ft above the plate. Determine the compression of each spring when the block momentarily comes to rest after striking the plate.
The cycle has a thermal efficiency of 35%, and steam changes from saturated vapor at 300 C during the heat addition process. If the mass flow rate of the steam is 2kg/s, determine the net power (kw) output of this engine.
An equal-tangent crest vertical curve is designed with a PVI at station 110+00 and a PVC at station 107+43.3. if the high point is station 110+75.5 what is the design speed of he curve?
The letter size is such that the sign can be ready by a person with 20/20 vision from a distance of 200 ft. Does the subject driver have enough time to read the sign at a speed of 30 mi/h
A 1047 steel plate is subjected to a tensile stress of 120 MPa. Given its fracture toughness is 45 MPa?m and Y = 1, (a) Determine the critical crack length to assure the plate will not fail under static loading.
An electrostatic precipitator (ESP) is being designed to collect flue gas particles at a power plant. The following information has been collected: electric field intensity = 100,000 V/m, and average particle charge = 0.30 fC (1 fC = 10-15 C).
