(shell and tube heat exchanger) water flowing at a rate of 3.8 kg/s is heated from 38°c to 55°c in the tubes of a shell-and-tube heat exchanger. the shell side is one-pass with water, flowing at 1.9 kg/s, entering at 94°c. the overall heat transfer coefficient is 1420 w/(m2*k). the average water velocity in the tubes (1.905 cm inner diameter with a wall thickness of 0.5 cm) is 0.366 m/s. because of space limitations, the tubes may not exceed 2.44 m in length. determine the required number of tube passes, the number of tubes per pass, and the length of tubes consistent with this restriction.

Abag of potato chips contains 2.00 l of air when it is sealed at sea level at a pressure of 1.00 atm and a temperature of 20.0 deg c. what will be the volume of the air in the bag if you take it with you, still sealed, to the mountains where the temperature is 7.00 deg c and atmospheric pressure is 70.0 kpa? assume that the bag behaves like a balloon and that the air in the bag is in thermal equilibrium with the outside air.
