A flow of 2.0 m3 /s is carried in a rectangular channel of 1.8 m width at a depth of 1.0 m (section 1). There is an upward step of 0.18 m together with a contraction where b reduces to 1.4 m (section 2).

a) Draw the side view and top view of the channel described above.

b) Calculate the specific energy at section 1 and plot the specific energy curve. Show y1, E1, V1 2 /2g on the curve.

c) Find the water depth on the step (i.e. y2) and check the choking condition (i.e. state if choking occurs).

d) If choking occurs what is the necessary change in specific energy and depth at section 1 to overcome choking?

Calculate the pressure drop (ft of water) over a distance of 800 ft within a PVC pipe carrying 750 ft3/min of landfill gas at 115 ºF. The cross-sectional area of the pipe interior is 0.0884 ft2 (d = 4.026 in). Assume the pressure in the pipeline is close to atmospheric (13.6 lb/in2) and the molecular weight of the gas is 28 lb/mol. Assume the gas is incompressible and the viscosity at 115 º is 7.65×10^-6lb/ft·s. The pipe relative roughnessis 1.5x10-5. Use the Moody diagram

  1. The ultimate BOD of a river just below a sewage outfall is 55.0 mg/L, and the DO is at a saturation value of 12.0 mg/L. The deoxygenation rate coefficient kd is 0.30/day, and the reaction rate coefficient kr is 0.90/day. The river is flowing at the speed if 52.0 miles per day. The only source of BOD on this river is this single outfall.

    1. Find the critical distance downstream at which DO is a minimum.

    2. Find the minimum DO.

    3. If a wastewater treatment plant is to be built, what fraction of the BOD would have

      to be removed from the sewage to assure a minimum of 5.0 mg/L everywhere

      downstream?

Multi-wells are used for dewatering at an excavation site. The dimension of the excavation pit is 150 m × 200 m. The height of the phreatic level above the impermeable layer before pumping is 15 m. The height of the phreatic level at the center of excavation pit after pumping is 6 m. The soil permeability k = 2.3×10-5 m/s. The wells have a diameter of 200 mm. Determine the number of wells required for this dewatering project

Vehicles arrive at a toll both starting at 7:00 A.M. at a rate of λ(t) = 5.1 – 0.05t [with λ(t) in veh/min and t in minutes after 7:00 A.M.]. The first operator processes cars at a rate of 3 veh/minute 7:00 A.M. until 7:15 A.M when the person leaves because of illness. From 7:15 A.M to 7:25 A.M, no one is at the toll booth but a new operator arrives at 7:25 A.M and processes at a rate of μ(t) = 8 + 0.3t [with μ(t) in veh/min and t in minutes after 7:25 A.M.]. Assuming D/D/1 queuing, what is the maximum queue length (in vehicles) and the average delay per vehicle?
