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

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?
