You are moving 300 CCY per hour of material from the cut to the fill along a haul road that is 6,000 lf long. The dry unit weight of the material is 2,500 lb/CCY with a 12% water content. The elevation of the cut is 500 feet above sea level. The project manager anticipates the completion of the embankment, which is at an elevation of 900 feet, can be completed in 65 hours using a spread of 4 scrapers, 2 dozers, 1 compactor, and a water truck. What is the grade resistance as a percent when hauling from the cut to the fill

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m

Wiy doeres rere okhn a pump whon working betwon the same pressure range?

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
