You are filling your beer mug from a keg. the pressure in the keg is 5 psig, the filling tube from the keg is 3 ft long with 1/4 in. id, and the valve is a diaphragm dam type. the tube is attached to the keg by a (threaded) tee, used as an elbow. if the beer leaving the tube is 1 ft above the level of the beer inside the keg and there is a 2 ft long, 1/4 in. id stainless steel tube inside the keg, how long will it take to fill your mug if it holds 500 cm^3 ? (beer: μ = 8 cp, rho = 64 lbm/ft3 )

Consider a 1.2 meter high and 2 meter wide glass window whose thickness is 6 mm and thermal conductivity is 0.78 w/m °c. the room temperature is maintained at 24 °c, while the outdoor temperature is -5 °c. the convective heat transfer coefficients on the inner and outer surfaces of the window are 10 w/m2 °c and 25 w/m2 °c respectively. (a) draw the thermal resistance network, etermine the steady rate of heat transfer t e glass window (c) determine the temperature of the inner surface of the window
