The airspeed indicator is quite a delicate instrument. You could damage it by blowing hard down the pipe, just using your mouth, not a air hose. The baffle is often contained in a screw-off end, of the pitot. This has a restricted hole, so that air passes through to transmit the pressure, relative to speed to the instrument.
The volume of air is kept very low, due to the restriction. Any dirt or insects that get through the larger hole in the "bullet" end of the pitot, should be stopped by the baffle.

Which are the other methods or devices use for the measurement of speed?
Jets use a pitot tube.
How speed calculated in aircraft?
One way to measure airspeed is to use a device called a pitot tube.
What is the use af a baffle plate in the storage tank?
To keep the liquid from sloshing around.
What is the tool use to measure speed?
An anemometer is used to measure wind speed. A Pitot Tube is used to infer speed in an aeroplane,. A speedometer in an ordinary car, and a microwave or laser radar in a Police car.
Could you please use baffle in a sentence?
Example sentence - Amanda's behavior continued to baffle the people around her.
How can i Remove the muffler baffles in a 1996 virago?
All you have to do is drill the rivets that you see holding the beauty plate in the ends of the muffler. After you do this the beauty plate will come off and reveal another plate. Then the tricky part. You will see the diameter of the inner baffle, you need to find to hole saws. 1 for the inner tube outside diameter and 1 for the inside diameter of the exhaust to cut out after drilling the inner exhaust one out. Then you can look in and notice the baffle being held in place in three spot wher it is welded to the inside diameter of the pipe. You can use a long saw saw blade or something to cut at it or as I have heard other ppl say they just grabbed it with some vise grips and wiggled and tugged on it till it broke free , either way gives you the same result"NO BAFFLE" You will probably like the sound better than factory but Keep in mind you virago will never sound like a Harley even with a nice set of Aftermarket slip ons. I know I have a XV1000 and have done the baffle removal and aftermarkets. Though they do sound good.
What is the difference between a manometer and a pitot?
A manometer is a device for measuring pressures, especially the word is used for pressure meters that are constructed to use a liquid in a transparent U-tube. A peizometer is specifically about measuring pressures in ground water wells.
Which valve is the preferred valve to use as flow control valve at the pump discharge 8 inch size ball valve can be used for the same application?
I would use a butterfly valve to set the flow and a pitot tube to measure it. Nexus Valve makes a good one and it is price competetive as well.
Would you please use 'baffle' in a sentence for me?
The more I text and use internet messaging, the poorer my spelling, grammar and composition skills become; I'm certain that one day I will forget them all and understandable communication will baffle me.
What unit measures tube current?
Measure the plate resistors' (R) voltage (E) and use Ohms law to convert that to amps (I). I=E/R
What is the rotameter orificemeter venturi meter pitiot tube i want to question related to these and answers?
AnswerThese are used to measure flow rate.Orifice PlateWith an orifice plate, the fluid flow is measured through the difference in pressure from the upstream side to the downstream side of a partially obstructed pipe. The plate obstructing the flow offers a precisely measured obstruction that narrows the pipe and forces the flowing fluid to constrict.The orifice plates are simple, cheap and can be delivered for almost any application in any material.The TurnDown Rate for orifice plates are less than 5:1. Their accuracy are poor at low flow rates. A high accuracy depend on an orifice plate in good shape, with a sharp edge to the upstream side. Wear reduces the accurVenturi TubeDue to simplicity and dependability, the Venturi tube flowmeter is often used in applications where it's necessary with higher TurnDown Rates, or lower pressure drops, than the orifice plate can provide.In the Venturi Tube the fluid flowrate is measured by reducing the cross sectional flow area in the flow path, generating a pressure difference. After the constricted area, the fluid is passes through a pressure recovery exit section, where up to 80% of the differential pressure generated at the constricted area, is recovered.With proper instrumentation and flow calibrating, the Venturi Tube flowrate can be reduced to about 10% of its full scale range with proper accuracy. This provides a TurnDown Rate 10:1.Variable Area Flowmeter or RotameterThe rotameter consists of a vertically oriented glass (or plastic) tube with a larger end at the top, and a metering float which is free to move within the tube. Fluid flow causes the float to rise in the tube as the upward pressure differential and buoyancy of the fluid overcome the effect of gravity.The float rises until the annular area between the float and tube increases sufficiently to allow a state of dynamic equilibrium between the upward differential pressure and buoyancy factors, and downward gravity factors.The height of the float is an indication of the flow rate. The tube can be calibrated and graduated in appropriate flow units.The rotameter meter typically have a TurnDown Ratio up to 12:1. The accuracy may be as good as 1% of full scale rating.Magnetic floats can be used for alarm and signal transmission functions.Pitot TubesThe pitot tube are one the most used (and cheapest) ways to measure fluid flow, especially in air applications as ventilation and HVAC systems, even used in airplanes for the speed measurent.The pitot tube measures the fluid flow velocity by converting the kinetic energy of the flow into potential energy.The use of the pitot tube is restricted to point measuring. With the "annubar", or multi-orifice pitot probe, the dynamic pressure can be measured across the velocity profile, and the annubar obtains an averaging effect.
What would make the plate of a vacuum tube glow bright red?
That bright red color is heat: infrared energy and visible light. The electrons gain kinetic energy as they accelerate away from the Cathode. As each electron is absorbed into the metal Plate, its kinetic energy becomes acoustic motion in the Plate's atoms - heat. (The plate is being hammered.)It is not normal for vacuum tube circuits to operate at high Plate temperatures that are this conspicuous. This circuit has an excessive product of Plate voltage times Plate current, and/or the vacuum tube Grids are biased incorrectly.One common technique for reducing this heating effect is to use a second Grid near the Plate that is biased much more positive than the Plate. This causes the electrons to decelerate between Grid 2 and the Plate - loosing most of their kinetic energy before absorbtion.
