Consider a 1.2-m-high and 2-m-wide glass window whose thickness is 6 mm and thermal conductivity isk 5 0.78 w/m·k. determine the steady rate of heat transferthrough this glass window and the temperature of its innersurface for a day during which the room is maintainedat 24°c while the temperature of the outdoors is 25°c. take the convection heat transfer coefficients on the innerand outer surfaces of the window to be h1 5 10 w/m2·kand h2 5 25 w/m2·k, and disregard any heat transfer byradiation

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

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)
