Consider an isothermal medium at temperature t, confined between two large, parallel black plates that are isothermal at the same) temperature tw. the medium is gray and absorbs and emits, but does not scatter. determine an expression for the heat transfer rates within discrete transfer method

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

What is the major difference between thermoplastics and thermosetting plastics from the polymerization structure point of view?

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)?
