Unit Conversion

Standard units are also called SI units. SI units are used for measuring a physical quantity satisfying certain conditions. There are two types of units: fundamental units and derived units. Fundamental units are physical quantities that are independent, that is, they do not depend on other quantities like mass, length, or time. There are plenty of quantities in our lives which need to be measured and compared. Measuring is the comparison of a particular physical quantity with its reference value. A unit is a measure of a fixed physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.

7.22 Casing with an ID of 10.05 in. and a strength in tension of 450,000 lbf in the joints and 629,000 lbf in the pipe body is being suspended from the surface while being cemented. If the effective weight of the casing being sup- ported is 240,000 lbf and a safety factor of 1.4 is desired, how much surface pump pressure can be applied safely to displace the cement? The casing burst is rated at 3,130 psi (for zero axial stress). Solve to the nearest correct solution

A flexible pavement at an access road to a sportsstadium parking lot is designed with a 4-inch sand-mixasphaltic concrete surface, 5-inch aggregate bituminousemulsion base, and a 10-inch crushed stone subbase.There are 95 scheduled baseball and football games atthe stadium per year. The access road to the parking lotis three lanes in each direction (conservativelydesigned). The pavement was designed for recreationalvehicles with one 20K single axle and one 20K tandemaxle. There are 9,000 recreational vehicles estimated ateach event. Given that drainage coefficients are 1.0, theoverall standard deviation of traffic is 0.45, reliability is90%, and the soil's resilient modulus is 15,000 lb/in2,how many years will the access road last if the initialPSI is 4.0 and the terminal serviceability index is 2.5?

Problem 1: A flexible pavement section is designed using a CBR of 20 for the subgrade. During construction it is found that the subgrade is softer with a CBR of 7. The contractor proposes to place a layer of select fill on top of the subgrade to compensate for this condition. How thick should the select fill layer be if the original pavement section is 8 inches HMA over 12 inches crushed aggregate base over subgrade. Assume a resilient modulus of 15,000 psi for the select fill and clearly describe the design method used to solve this problem as well as any assumptions and results PROBLEM 2: Design a rigid pavement that will last as long as the flexible structure from problem 1
