The weir/saddle type diaphragm valve is the most common diaphragm valve design [1]. Its design uses a raised lip on the pipe body that comes into contact with the diaphragm. Therefore, the diaphragm in a weir type valve is generally smaller and does not need to be as flexible as other types due to its relatively shorter distance of travel ...

Kettle type reboilers are a type of shell-and-tube heat exchangers. A tube bundle is a number of pipes containing a heating medium, commonly saturated steam, that provides heat to the fluid. Baffles are located along the length of the reboiler to help facilitate movement and heat transfer in the reboiler. Eventually, the fluid undergoes a phase ...

The bottom edge over which the water flows is called the sill or the crest of water the notch. The common shapes of weirs are, rectangular, triangular, trapezoidal, composite, parabolic and proportional. The sheet of water which springs free from the crest is called the nappe. If the sheet of water springs free as it leaves the crest, the weir ...
