Liquid water at 35ºFis fed to a boiler operating at 10 bars and is converted at constant pressure to saturated steam. The steam is produced at a steady state flow rate of 600 lbm/hr. Assume that the kinetic energy of the liquid entering the boiler isnegligible, and that the steam is discharged from the boiler through a 1 ftpipe. a. Calculate ∆Ĥ (in units of Btu/lbm) for this process.
b. Calculate the heat input (Btu/hr) to meet the needed saturated steam production

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)?
