What is the application of Bernoulli theorem?

The only certain application of Bernoulli's Theorem I know is in the Bernoulli's Theorem experiment in college. All other examples are in my opinion a restatement of Newtons Laws, a missinterpretation of results or a failure to fully understand what is physically happening such as in the fallacy that lift in an aerofoil is due to BT. Bernoulli's Theorem is used by the Fire Brigade to calculate velocity and range of different types of fire-fighting equipment. Going hand-in-hand with the Venturi effect, it help to calculate reach and pressure required to obtain that reach during fire-fighting operations. Example: A pump supplies 6kW of energy to the water flowing thorugh a 45mm hose. If the water flows 25m vertically and through a 25mm branch at a rate of 480l/min, use Bernoulli's equation to find pressure at the branch.


What is more fire resistant steel or concrete?

Concrete is much more fire resistant. This is shown by the design of reinforced concrete structure where the steel is placed within the concrete. A major reason is that the concrete protects the steel from any fire. Steel only construction requires the steel to be covered in a fire protection material.


What is furnance masonry?

certain furnaces use fire bricks to prevent hotspots and to help retain heat within the fire box, this is where you would find masonry in a furnace application. in most cases the fire blocks are dry stacked along the sides and bottom.


What is the maximum pressure for a fire hydrant which the firefighter could deal with?

A fire hydrant is normally pressure regulated to 7.0barg which will be reduced to around 3.5barg at the nozzle end.


When do you need stortz connection?

Stortz connections are used to connected lengths of fire department water supply hose, or to connect a fire pumper to a structure's sprinkler and/or standpipe system. They provide a 1/4 turn 'sexless' connection, which is normally faster and easier to complete than a threaded coupling. The type of connection used to supply a structure is regulated by the fire code that applies to the jusisdiction where the structure is located. Designers and engineers should consult with their local Fire Marshal to determine the correct type of connection for their local. Using this type of connection for fire department supply hose depends on the standard operating procedures for hose in place at the fire department. Designers and engineers should conact their Fire Chief's office to determine these procedures.
