Two oil tanks are connected by two 9-m-long pipes, as in fig. p6.26. pipe 1 is 5 cm in diameter and is 6 m higher than pipe 2. it is found that the flow rate in pipe 2 is twice as large as the flow in pipe 1. (a) what is the diameter of pipe 2? (b) are both pipe flows laminar? (c) what is the flow rate in pipe 2 (m3/s)? neglect minor losses.

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
