Water is the working fluid in a rankine cycle. superheated vapor enters the turbine at 8 mpa, 5608c with a mass flow rate of 7.8 kg/s and exits at 8 kpa. saturated liquid enters the pump at 8 kpa. the isentropic turbine efficiency is 88%, and the isentropic pump efficiency is 82%. cooling water enters the condenser at 188c and exits at 368c with no significant change in pressure. determine (a) the net power developed, in kw. (b) the thermal efficiency. (c) the mass flow rate of cooling water, in kg/s.

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

10 kg of co2 is initially contained at 400 kpa and 300 k. the gas constant for carbon dioxide is 189 j/lkg k) and has a specific heat ratio, k, of 1.289. isentropic expansion then occurs until the pressure is 200 kpa. a) determine the initial volume of co2 in m. b) determine the final temperature in k. c) determine the work done by the system during the expansion kl.

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)?
