Prepare a preliminary design of a system to collect dust from a plant under the following conditions:Sample of Dust: 50% by wt. below 30 micrometers; 80% by wt. below 70 micrometersDensity= 2.5 g/cubic cmGas Flow Rate: 30,000 acfm (actual cubic feet per minute) +- 5000Particle Loading: 0.5 to 4 grains/cubic feet, avg=1.5 grains/cubic footEmission Limit: 1.5 lb/hrDesign a cyclone collection system which might meet the minimum limits. Provide a reasonable pressure drop through the cyclone (i.e., 8-10 in H2O)
This uniformly reduces 4X10-4 cm / s to a depth of 22 meters. If the water level is about 3 feet below the surface, determine the saturated hydraulic conductivity of the layer.
A well water has the following mineral contents in mg/L: Na+=20; K+=35; Ca+2 =15; Mg+2 =10; Sr=0.5; Cl- =40; HCO3- =65; CO3-2=5; SO4-2=15; and NO3=10.
A 2000 ft vertical curve connects to a +3% grade to a -5% grade. If the vertical tangents intersect at station 52+60.55 and elevation 877.62 ft, calculate the elavations at the VPC, VPT, high point and station 54+00.
The receiver's velocity is constant at 10 yd/sec, and he catches passes when the ball is 6 ft. above the ground. If the quarterback desires the receiver to catch the ball 2.5 sec. after the launch instant, determine the initial speed v0 and angle,..
I want to use PESTAN model for a project, can you please tell me any real scenario with available data on which I can formulate a project preferably related to oklahoma.
The steel ball is suspended from the accelerating frame by the two cords A and B. Determine the acceleration a of the frame which will cause the tension in A to be twice that in B.
Two ropes are attached to the eye bracket. The resultant force R of the two forces equals 1000-lb and the line of action is directed along the x-axis. if the magnitude of force F1 is 250-lb, determine the magnitude of force F2 and the angle
Two strips of a plastics material are bonded together as shown. The average shearing stress in the glue must be limited to 1000 kpa.
A 4000-m 3 /day conventional activated sludge plant has an influent with a BOD5 of 190 mg/L and SS of 225 mg/L. What population would this plant serve?
The treated wastewater has a BOD of 12 mg/L and a k of 0.0338 1/d. The Broad River has a flow rate of 0.43 m3/s and an ultimate BOD of 5.0 mg/L.
A driver is traveling 68 mi/h on a road with a -3% grade. There is a stalled car on the road 1000 ft ahead of the driver. The driver's vehicle has a braking efficiency of 90% and anti-lock brakes.
Measurements indicate that to cause this flow the force acting on the contents of the control volume is 40i lb. Determine the net rate of flow of linear momentum through the control surface.
