The steady-state temperature distribution in a one-dimensional wall of thermal conductivity 50 w/m k and thickness 50 mm is observed to be t(°c)=a+bx2, where a 200°c, b=-2000°c/m^2, and x is in meters. (a) what is the heat generation rate q in the wall? (b) determine the heat fluxes at the two wall faces. in what manner are these heat fluxes related to the heat generation rate

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater

The filament of an incandescent lamp has a temperature of 2000k. calculate the fraction of radiation emitted in the visible light band if the filament is approximated as blackbody
