In case of venturi meter, at the diverging section mach number is less than 1. however in diverging section of a nozzle mach number is greater than 1.
Convergent nozzle and divergent nozzle
In Venturi meter losses are less so coefficient of discharge is higher whereas in orifice meter due to no convergent and divergent cones there are more losses and hence its coefficient of discharge is less.In venturi meter losses are low due to steamline shape of the diffuser and the pressure gradient is not abrupt as in case of orifice meter.
Venturi Meter is a device used for measuring the flow of the fluid.
the induction of gas is forcedthrough a venturi design, causing higher tempuratures. Increasing combustion rate. Causing high efficiency.
1. It is used for flow measerment with minimum head loss. 2. It is used in industries for flow measerment of chemicals. 3. it is also used in the airoplane for measurment of speed of plane.
A Venturi draft regulator is another device to control the overfire pressure in the fire box of a furnace or boiler.The standard draft regulator such as the Fields control uses the principal that hot gases are lighter than cold and therefor tend to rise.The Venturi Draft Regulator invented by Lionel Scott telephone #9o2-667-4133. This device uses the Bernoulli principal which the carburetor uses. When the hot gases move through the venturi tee where the Draft control door is located it causes a drop in pressure which causes the door to open .This is where it is hard to understand,to obtain the proper over fire pressure the weight on the door would have to be heavier than what it would be on the standard set up such as the Field control.The benefit of this is that when the fire is off the flue pressure has to be higher than the set over fire pressure before the regulator door will open,therefore less room air is exhausted up the flue.Also when the fire is on less room air is pulled into the gases and therefor the temperature of the gases is higher entering the flue.Thus more heat can be put into the home, the result is the A.F.U.E. is higher.
why lenght of divergent cone is larger than convergent cone in venturi meter
In Venturi meter losses are less so coefficient of discharge is higher whereas in orifice meter due to no convergent and divergent cones there are more losses and hence its coefficient of discharge is less.In venturi meter losses are low due to steamline shape of the diffuser and the pressure gradient is not abrupt as in case of orifice meter.
What is a Venturi?
The sprinkler head design. High velocity heads have longer nozzles with a venturi tube (a type of curved nozzle) which increases the velocity of the water spray. Medium velocity heads are shorter and do not use a venturi.
