A tidal channel, which may be assumed to be rectangular, is 40 m wide and conveys a discharge of 60 m3/s at a depth of 1.52 m. A tidal bore is seen to propagate upstream with a wave speed of 5 m/s. Determine the depth of flow and the discharge immediately after the bore has passed.
Tidal BoreVw = c1 - V1 or Vw = c2 + V2
If water at 70 degrees C (row=1.94 slugs/ft^3, vapor pressue= 0.363psia) is used in a simple barometer what is the height of the column of water if the atmospheric pressure is 15 psia
Two rectangular primary sedimentation tanks each 27 m long, 5 m wide and 3.8m deep treat 6000 m3/day wastewater from a community. Total effluent weir length is 50m (both tanks).
Draw block diagrams of the unit operations necessary to treat the following wastes to effluent levels of BOD5 = 200 mg/L, SS = 100 mg/L, P = 5 mg / L (required for discharge into a sanitary sewer).
After drying in the oven, it weighs 4.44 kg. The relative density of the grains is 2.70. Determine the degree of saturation, void ratio, porosity and moisture content of the soil in its natural state.
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.
Complete a maximum demand calculation for a fully air conditioned hospital with the following electrical equipment and outlets. 500, 28W lamps 200, 14W lamps 400, 10A socket outlets 5, 18A, 3 phase, air conditioning units
you measure the average headway and average spacing of passing vehicles as 3.2 seconds and 165 ft, repsectively. calculate the flow, average speed, and density of the traffic stream in this lane.
All the silt is saturated even after the water table is lowered. (In this problem, treat the unit weight above the water table as bulk unit weight and the unit weight below the water table as saturated unit weight.)
in a hydrometer test , the results are as follows:Gs =2.60 , temperature of water=24c ,and R=43at 60 min after the start of sedimentation . what is the diameter , D, of the smallest -size particles
At a distance of 20 km downstream of the plant, the river has an ultimate CBOD of 10 mg/L. The state has set an ultimate CBOD discharge limit for the treatment plant of 2000 kg/day.
Ignoring both axial and shear deformations and using the unit force method, calculate the vertical displacement of joint B.
The 20-lb cart B is supported on rollers of negligible size. If a 10-lb suitcase A is thrown horizontally on it at 10 ft/s, determine the length of time that A slides relative to B, and the final velocity of A and B. The coefficient of kinetic fri..
