True or False: A trial assembly allows you to adjust all clamps to the correct width.
True or False: Miter joints can be used to join two pieces having different widths.
True or False: If the second piece of the joint fits a bit snugly into the first piece, use sandpaper to smooth out the channel.

A shell-and-tube heat exchanger has one pass on the shell side and two passes on the tube side (i.e.al-2shell and tube heat exchanger). It is being used for oil cooling. The oil flows in the tube side. It enters at 1120C and leaves at 78 0C The shell-and-tube fluid is water at a flow rate of1.35 kg/s, entering at 360C and leaving at 78 0C. The heat capacity of water is 4180j/(kg. K), and the overall heat transfer coefficient for the heat exchanger is 350 W/(m2.K). The geometry factor, F is 1.15. Determine the heat transfer area required for the unit.
