1. You are located downwind from two oil-burning power plants. One is located 0.3 km NE of your location and burns 1400 kg of 0.5% sulfur oil per hour. Its effective height is 60 m. The second plant is located 0.5 km NNW of you and burns 1600 kg/hr of fuel oil containing 0.75% sulfur. The effective height is 40 m. The wind is blowing from NNE at 3.3 m/s (measured at the standard height of 10 m). For a class B stability condition, what is the SO2 concentration at your location at ground level?

So question. We are covering fertilizer calculations in class. we did not go over examples and i know its easy but i still get confused because one little mistake can ruin the problem. Here is the question: If the K requirement of bent grass is 1lb K/1000 ft2 per year and all 18 greens of a golf course is equal to the acreage given in Q9 ( green acres 1.8), how many lb of 0-0-60 must you purchase to meet the K needs of all greens?

2. A suspension cable has a span of 160 m and central dip of 16m. It carries a load of 5kN/m of horizontal length. Calculate the maximum and minimum tension in the cable. Find the horizontal and vertical forces in each pier under the following conditions: a) If the cable passes over frictionless rollers on the top of the pier. b) If the cable is firmly clamped to saddles on frictionless rollers on the top of piers. In each case, the back stay is inclined at 300 with the horizontal.

ENGINEERING CONTRACTS

Review the information below. In 150-300 words for Part A, determine who is liable for the flood and why.  Be sure to show all your reasoning and describe how and why the specification may determine which party is liable. See Lectures 8-12 or Chapters 31 and 32 in the book.

GBS sued to recover the balance due under a contract with the federal government to build a dry dock at the Brooklyn Navy Yard according to plans and specifications the government prepared. The work required GBS to relocate a sewer main.   The specification of work was created by the federal government and specifically prescribed the dimensions, material and location of the section to be substituted. In addition, the federal government provided all drawings to GBS. GBS completed the relocation by exactly following the specification that was specified by the federal government.

About a year a later, a heavy rain and high tide caused the sewer relocated by GBS to overflow before the dry dock was completed, causing the excavation of the dry dock to be flooded. An investigation revealed that an existing internal dam had diverted the water into a portion of the sewer that overflowed into the dry dock. The internal dam was an existing feature but was not shown on the plan and specifications the government gave to GBS. GBS and the federal government each claimed the other was responsible for the flood. Eventually, the government canceled GBS’s contract and completed the work with a replacement contractor. At the time the contract was canceled, GBS was not fully paid.

A water tower supplies water to a city through a pipe with 1 ft diameter. The pipe is 0.5 miles long and is made of commercial steel pipe. Over the years, the supply line lost head and engineers are considering the replacement of 94 percent of the pipe length with a larger diameter pipe (same type). The peak water demand is 3.53 ft3/sec. How much pressure head could be gained by this strategy?
