There are two types of surface blowdown fittings. The simpler is a pipe entering the steam drum at the normal water level. A more sophisticated skimmer arrangement attaches a swivel joint to the pipe for a short length of pipe suspended by a float. [2] The skimmer may be more effective at removing floating oil which might otherwise cause foaming.
In the oldest modern hydronic heating technology, a single-pipe steam system delivers steam to the radiators where the steam gives up its heat and is condensed back to water. The radiators and steam supply pipes are pitched so that gravity eventually takes this condensate back down through the steam supply piping to the boiler where it can once ...
Steam pipes and radiators are prone to producing banging sounds called steam hammer. The bang is created when some of the steam condenses into water in a horizontal section of the steam piping. Subsequently, steam picks up the water, forms a "slug" and hurls it at high velocity into a pipe fitting, creating a loud hammering noise and greatly ...

The majority of local plumbing ordinances required the use of wrought or cast iron and limited the use of lead pipes to connectors (goose-necks or pig-tails) or placed other restrictions on lead pipes. As noted above, the San Jose plumbing ordinance does not list lead as an approved pipe material which is similar to the Los Angeles ordinance ...

The larger pipe was glass so the behaviour of the layer of the dyed stream could be observed. At the end of this pipe, there was a flow control valve used to vary the water velocity inside the tube. When the velocity was low, the dyed layer remained distinct throughout the entire length of the large tube.
In fluid dynamics, the entrance length is the distance a flow travels after entering a pipe before the flow becomes fully developed. [1] Entrance length refers to the length of the entry region, the area following the pipe entrance where effects originating from the interior wall of the pipe propagate into the flow as an expanding boundary layer.
