1.Compute the amount of chlorine required for disinfection in pounds per day(lb/d). Estimate the annual cost for disinfection using chlorine.
Flow Rate= 30 milloin gallons per day.
2.Determine appropriate dimensions of the finished water clearwells to achieve adequate disinfection using chlorine. Flow Rate Q = 30 million gallons paer day.
3.Cylinders C and D are attached to the end of the cable. if D has a mass of 600 kg, determine the required mass of C, the maximum sag h of the cable, and the length of the cable between the pulleys A and B. The Beam has a mass per unit length of 50 kg/m.
A runs slope a distance of 156.777 m from one point to another point at a rate of +1.5%. What is the corresponding horizontal distance between the points?
A uniform crate weighing 15.0 kN is lifted by a sling, ABC, a small pulley and cable BD. If the tension in the sling is limited to 9.0 kN, determine the minimum length of the sling. Neglect the radius of the pulley.
A worker slowly moves a 50-kg crate to the left along a loading dock by applying a force P at corner B as shown. Knowing that the crate starts to tip at about the edge E of the loading dock when a= 200mm, determine:
An undisturbed soil sample was collected in a sampling tube of internal diameter 5cm. The length of the extracted sample was 10.2 cm and its mass was 360 g. After oven drying the mass reduced to 326.5 g.
a beam is made by bonding a brass core to a steel tube and is subjected to a bending moment as shown. knowing that b
A fluid in an aquifer is 23.6m above a reference datum; the fluid pressure is 4390 N/m2. The fluid density is 0.999E3 kg/m3. What is the total energy per unit mass What is the total energy per unit weight
A balloon is to be used to carry meteorological instruments to an elevation of 15,000 ft where the air pressure is 8.1 psia. The balloon is to be filled with helium, and the material from which it is to be fabricated weighs 0.01 lbf/ft^2.
Compare the effectiveness of the zinc coating with a typical epoxy coating on reinforcement. How does the epoxy coating protect reinforcement and what happens if the coating is nicked.
Determine from curve (a) critical depth (b) the maximum flow rate (c) the flow rate at a depth of 2.4 m and (d) the depths at which flow rate of 28.3 m^3/s may exist and the flow conditions at these depths.
A 301 stainless steel wire is suspended vertically from itsend. The wire is 400 ft long, diameter .75 inches, specific weight= 489 lb/ cubic foot.
A trapezoidal channel with a bottom width of 4 feet and side slopes 2:1 (H:V) and a bed slope of 1 percent conveys a discharge of 50,000 gpm. Assume n = 0.025. Compute the normal depth.
