A watershed near Van Horn, Texas, has an area of 5500 acres. Land cover throughout the watershed is fair condition desert shrub dominated by saltbrush and greasewood. Hydrologic soil groups in the watershed are approximately 60% C and 40% D. Topography in the watershed includes high hills along the upper watershed boundary draining into wide, flat floodplains. Because of this changing topography, water flowing from the most hydraulically remote point of the watershed to the outlet passes through two distinct sections. The first section has a length of 1200 ft with an average slope of 4%. The second section has a length of 3200 ft and an average slope of 0.8%. Required:
Using the SCS Method, estimate the peak runoff rate, q, for a 25-year storm. You may assume no ponding occurs in the watershed.

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)?
