It is proposed to construct a new National Highway with four lane dual carriageway. The initial traffic in the year of completion construction i 1100CVPD. Assume the necessary data required for the design of flexible pavement and check for fatigue and rutting criteria as per IRC37. The given site is having moderate quality of soil with CBR of 6%. Design the flexible pavement for 15 years of design life by IRC method
Overnight a thin layer of ice forms on the surface of a 40-ft-wide river that is essentially of rectangular cross-sectional shape. Under these conditions, the flow depth is 3 ft. During the following day the sun melts the ice cover.
An 18 in. newriveted steel pipe 1000 ft long runs from elevation 150 ft toelevation 200 ft. If the pressure at elevation 150 ft is 100 psiand at elevation 200 ft is 72 psi, what flowrate can be expectedthrough the line? (use e = 0.003 ft)
The cross-section of a jet engine is shown in Fig. 6.1. On the basis of the topics covered in this book, select any three individual components of such an engine and describe the materials and processes that you would use in making them in quantit..
The hollow circular shaft is subjected to the torque of 4 kN # m. Determine the principal stress developed at a point on the surface of the shaft.
The heat resisting alloy S-590 is used for a component that will be exposed to 700°C. With a safety factor of two on the time, determine the maximum static stress the component must sustain in order to have a service life of 10000 hours.
A large tank is used to calibrate the reading from a flow meter. Measurements of the system weight as a function of time are made. Water enters the tank vertically from the flow metering system at a speed of 20 ft/sec through a 1.5 in.
Consider a small town in the Phillippines, where the average weight of people is 55 kg, and the average lifespan is 60 years. The people here eat lots of fish due to abundant availability from the local river.
The siphon crown is 1.2m above the water surface elevation of the reservoir and a length 10m away from the siphon entrance. If the siphon diameter is 30 cm, if the friction factor is .02, and the headless coefficient are .2 (inlet) and 1 (exit),
A water supplier wants to inject ozone into a piper bringing water to the water treatment plant to predisinfect the influent. The 3.0-ft diameter piper is 3,400 feet long with a steady flow rate of 10,000 gal/min.
Steam enters a nozzle at 400oC and 800 kPa with a velocity of 10 m/s, and leaves at 300oC and 200 kPa while losing heat at a rate of 25 kW. For an inlet area 0f 800 cm2, determine the velocity and the volume flow rate of the steam at the nozzle ex..
Determine the maximum force that the weight of stacked collars can exert on a drill bit, without the string of collars buckling. Take the steel collars to have an outer diameter of 7 in. and an inner diameter of 2.81 in.
A suburban street receives storm water runoff at a rate of 2.0 L/m-s (one each side). the street has a slope of .8 percent and a cross slope of 2 percent, n = .013.
