Pick out the wrong statement pertaining to shell and tube heat exchanger.

Bracket supports are used for horizontal shell, while saddle support is used for vertical shell

Clearance between shell & baffles and between tube & baffles should be minimum to avoid by-passing of the fluid, but it should be enough to permit the removal of tube bundle

Baffles are supported independently of the tubes by tie rods and positioned by spacers

Tie rods are fixed at one end in the tube sheet by making blind holes and the minimum number of tie rods is 4 with at least 10 mm diameter
