A water pipeline system is made up of three links in parallel. In any given year, on average, 99 in 100 pumps do not fail. The conditions in the links are statistically independent of each other.
A) If system failure occurs when any two of the three pumps fail, compute the probability of failure in the pipeline system.
B) What is the reliability of the system (i.e. probability of system success)?
1. the maximum eight-hour average concentration of carbon monoxide co in an urban area is measured to be 15 ppm. the
An engineer is required to survey a nonrectangular plot of land but is unable to measure side UT directly (see Figure 2.11). The following data are taken: RU=130.0m, RS=120.0m, ST=90.0m, angle RST= 115 degrees, and angle RUT= 100 degrees.Calculate th..
A hydraulic cylinder must produce a minimum force of 3 kN for a pressure of 800 kPa. What minimum diameter piston is required
A 12in diameter water main in your city has become very rough due to rust and corrosion, it has been suggested that the flowrate through the this pipe can be increased by inserting a smooth plastic liner into the pipe.
A flow of 4.8 m3/s is to be developed from a 500 km2 watershed. The reservoir is estimated to cover 1,700 ha. The annual rainfall is 97 cm, the annual runoff is 30 cm, and the annual evaporation is 120 cm
A dam is inclined at an angle of 30o from thevertical and has the shape of an isosceles trapezoid 100 ft wide atthe top and 50 feet wide at the bottom and with a slant height of70 ft. Find the hydrostatic force on the dam when it is full ofwater?
Discuss the effects of the project on the local community of the project described below 1.) The social, economic and environmental significance of the project within the local community 2.) The good, and bad impacts the project might have.
The segments of pipe and couplings used for drilling an oil well 15,000 ft deep are made of A-36 steel weighing 20 lb/ft. They have an outside diameter of 5.50 in. and an inside diameter of 4.75 in.
A wastewater is discharged to a stream with a reoxygenation constant of 0.5 day-1 and a velocity of 1 m/sec. The oxygen saturation concentration in the stream is 11 mg/L.
Starting from rest, a 4.0-kg body reaches a speed of 8.0 m/s in 2.0 s. What is the net force acting on the body?
A cyclone is designed with an inlet width (W) of 12.0 cm and has four effective turns. The inlet gas velocity is 15.0 m/s and the particle density is 1.70 g/cm3. (a) Estimate the particle size that will be collected with 50 % efficiency.
Start from the values for the density and the kinematic viscosity of CO2 at 15o C and standard atmospheric pressure (101.3 kPa), and first determine the value of the dynamic viscosity at the same conditions.
