A basket strainer is installed in a 15-cm diameter pipe. Pressure gauges are installed immediately upstream and downstream of the basket strainer. When water flows at 100 m3/hr, the pressure gauge immediately upstream of the basket strainer measures 1 bar.
a. When the basket strainer is clean, the pressure immediately downstream measures 0.9 bar. Calculate the local loss coefficient of the clean basket strainer.
b. When the pressure drops across the basket strainer by half (i.e., to 0.5 bar after the strainer) at the 100 m3/hr flow rate, it is removed for cleaning. What is the local loss coefficient of the basket strainer at this point?
Roe is the ratio of nonprestressed reinforcement in a section, and roe balanced is the ratio of tensile reinforcing producing balanced strain condition. Show cross sections, including bar sizes, arrangements, and spacing.
Calculate the surface area required for a stabilization pond to serve a domestic population of 1000. Assume 80 gpcd at 210 mg/l of BOD. Use a design loading of 20 lb of BOD/acre/day.
For a 30ft simply supported beam, there is a uniform load of 1.5 k/ft. along the length and two point loads of 20 kips each spaced at (from x=0 to x=30ft left to right) x=10ft and x= 20 ft.
a draw the shearing force diagram and the moment diagram of the following problem. the beam is indeterminate. you need
a wheel barrow is used to lift a 200lb load. the lenght from the wheel axle to the center of the load is 2ft. the length from the wheel and axle to the effort is 5 ft. illustrate and annotate the lever system.
The initial velocity of a 15-lb block is given as mv1=15i+15j (ft/s). A force defined by F=250i-250tj (lb) acts on the particle from time t=0 to time t=0.3 s for a total duration of 0.3 s.
Axis Chemical Company needs you to design a gravity sewer to convey 1,750 GPM of toxic waste. The pipe is to be glass-lined reinforced concrete (n = 0.009). Which pipe would you suggest the Joker use
The total volume of the house is 650 m3 (assume that the volume is well mixed throughout). The radon source emits 250 pCi/s (A picoCurie [pCi] is a unit proportional to the amount of radon gas and indicates the amount of radioactivity of the gas)
A year after buying her car, Anita has been offered a job in Europe. Her car loan is for $15,000 at a 9% nominal interest rate for 60 months. If she can sell the car for $12,000, how much does she get to keep after paying off the loan
if you had a choice of three kinds of aggregate--a sandstone,a crushed basalt,and a quartizite,you may select the basalt.Give one possible characteristic or property of sanstone and of the quartzite that made you decide not to select it for your c..
