Grade stakes for a pipeline running between stations 0 + 00 and 6 + 37 are to be set at each full station. Elevations of the pipe invert must be 843.95 ft at station0 + 00 and 847.22 ft at 6 + 37, with a uniform grade between. After staking an offset centerline, an instrument is set up nearby, and a plus sight of 5.32 taken on BMA (elevation 853.63 ft). The following minus sights are taken with the rod held on ground at each stake: (0 + 00, 5.36); (1 + 00, 5.86); (2 + 00, 5.88); (3 + 00, 6.47); (4 + 00, 7.53); (5 + 00, 8.42); (6 + 00, 8.89); (6 + 37, 9.12); and (A, 5.36). Prepare a set of suitable field notes for this project (see Plate B.6 in Appendix B) and compute the cut required at each stake. Close the level circuit on the benchmark.
Determine the initial acceleration of the 15-kg block if (a) T = 23 N and (b) T = 26N. The system is initially at rest with no slack in the cable, and the mass and friction of the pulleys are negligible
An interesting application of the relative motion equations is the experimental determination of the speed at which rain falls. Say you perform an experiment in your car in which you park your car in the rain and measure the angle the falling rain..
Consider two strata of the same soil material that lie between two channels. The first stratum is confined, and the second one is unconfined, and the water surface elevations in the channels are 24 m and 16 m above the bottom of the unconfined aquife..
A wave has a height of 1.5 m in water 5 m deep and a wave period of 6 s. Plot the horizontal component of velocity, the vertical component of acceleration, and the dynamic pressure at a point 2 m below the still water level versus time for a 6-s inte..
Consider a steady-flow Carnot refrigeration cycle that uses refrigerant-134a as the working fluid. The maximum and minimum temperatures in the cycle are 30 and -20°C, respectively.
Use the randn function to create 1000 values in a normal (Gaussian) distribution of numbers with a mean of 70 and a standard deviation of 3.5. Create a histogram of the data set you calculated.
Size an orifice and a weir for problem 2 on page 398 and 399 of the text book to achieve a flow rate of 1 cfs at an elevation of 102.5 feet and a total flow rate of 50 cfs at an elevation of 106 feet
Equation for head loss in a pipe when it is laminar flow: head loss, h= (32*dynamic viscosity,u*pipe length,L*average velocity of fluid,V) / (gravitational acceleration,g*pipe diameter,D^2) Give an equation for relative uncertainty of head loss
A $78,000 invtestment in machinery is proposed. It is anticipated that this investment will cause a reduction in net annual operating disbursements fo $16,300 a year for 12 years. The investement will be depreciated for income tax purposes
A developer has requested permission to build a large retail store at a location adjacent to the intersection of an undivided four-lane major road and a two-lane minor road. Traffic on the minor road is controlled by a stop sign.
how many flight lines will be needed to cover the tract for the data given in Problems?
For a ternary system, three components are present; temperature is also a variable. What is the maximum number of phases that may be present for a ternary system, assuming that pressure is held constant?
