1.We want to transport 350 gpm of fluid through a 4 inch pipe, where the available pressure drop is 30 psi per 1000 ft. The fluid properties are SG = 0.80 and µ=0.3 cP. Is a 4 inch pipe big enough?
2.A 20Kg package is at rest on an incline when a force P is applied to it. Determine the magnitude of P if 10sec is required for the package to travel 5 m up the incline. The static and kinetic coefficients of friction between the package and the incline are both equal to 0.3.
3.Determine the minimum length of a crest vertical curve if the grades are +4% and -2%, Design speed is 70 mi/h. State assumptions used in solving this problem.
Tensile tests of structural steel indicate that it fails when the axial tensile strain is 1800mu. Determine the maximum change in length that a 0:25-in diameter structural steel rod in tension can withstand before failure if it is 24 in in length
