What is the difference between HVAC diffuser's neck velocity and face velocity?
In HVAC terminology, a diffuser's neck velocity is defined as the velocity of air traveling through the duct work to the air outlet or inlet. The difference of the face velocity is this is a measurement of fume hood performance.
What is formula for converting face velocity into cubic feet per minute?
You need to know the area of the pipe or duct. If you have that area, in square feet, V = Q/A where V = velocity (ft/minute in this case), Q = flowrate (cubic feet/minute in ths case), and A = area (square feet in this case). Then, you just have to apply conversions to get whatever units you want to present or use the answer in.
How many times greater is the force of collision if the driving speed is doubled?
Answer: It depends. The "force" of the impact depends on the momentum of the object. Momentum depends on mass and velocity. If the mass and velocity are constant, then extending the time of impact will not change the momentum. Suppose you stand 10 feet away from me and I throw a brick at your face. Then suppose you stand 40 feet away and I throw the same brick at your face. It's going to hurt you about the same amount (ignoring gravity and air resistance). Suppose you are 40 feet above me and I throw a brick at your face. It will hurt less, because gravity will be slowing down the brick. Suppose I am 40 feet above you and I throw a brick at your face. It will hurt more, because gravity will be speeding up the brick. john
How do you demagnetize a TV?
A "degaussing coil" is used to demagnetize the cathode ray tube (CRT) types of television. LCD and plasma type TVs would NOT need this done. What would happen on CRTs is if they were exposed to some other external magnetic fields, it would cause the electron beam that creates the illumination on the screen to deviate from its intended position, thereby causing color "splotches". The degaussing coil is a round-shaped hoop usually powered by a 120 VAC wall outlet (in the US) creating a fluctuating magnetic field. The technician starts close to the face of the TV and moves the hoop in a circular motion (you'll see the screen make some really rainbow-like colors) and SLOWLY backs it away from the screen. When you no longer see any effect from the degaussing coil, the process is complete. Newer TVs usually had a degaussing coil built into the TV set, which it would energize occasionally to keep the screen degaussed.
How Can A Skydiver Increase his or her terminal velocity?
The less air resistance the faster he can go. By pointing his face or feet down and holding his arms close to his body he minimizes air resistance and falls faster. By positioning his body parallel to the ground and spreading out his limbs he maximizes air resistance and will fall slower. The type of clothing worn also has an effect. A loose fitting fabric jumpsuit will tend to reduce terminal velocity and a tight fitting nylon jumpsuit will increase it. Some jumpers wear lead weight to adjust their fallrate. This is usually so slim light jumpers can match their fallrate with heavier jumpers.
If the coil face velocity is 500fpm with a 14fins inch find the number of rows for the coil?
hi dear , the number of rows for this coil is 6 rows , but there is another factor , u have to take in cosideration the capacity ( BTU ) , thanks

How do you clean egniton coil on Briggs and stratton engine?
Remove the shrouds then you can do it in two ways .If the coil is already set right you can pull the fly wheel and sand or wire brush the face of the coil .You can remove the coil and leave the fly wheel in place.You will have to pull the spark wire off the spark plug ,remove the bolts holding the coil in place (move the magnet so it is away from in front of the coil first) ,lift coil remove wire off spade connector .Then you can clean the coil with a wire brush or sand paper (you need to clean the face and the fly wheel face and make sure you wipe so no dirt is left) the you reverse the removal and reset the coil if you have a manual it will give you proper coil gap. If not you can use a thick peace of paper to gap it.

Why shouldn't corticosteroid creams be used on your face?
Corticosteroids can be used on your face but it is recommended that you don't use anything stronger then 1% because it can cause skin thinning.
What is the recommended temperatures for an individual to wear the North Face Triclimate jacket?
There is no absolute recommended temperatures for the North Face Triclimate jacket to be wearable. Given it's removable layers it is suitable from early Autumn, through Winter and even Spring in some combination or other.
Why is it necessary to consider positive and negative terminals of the ammeter when you connect leads from it to the circuit?
When you are dealing with DC voltages polarity is very important. Inside the ammeter is a coil through which the circuit amperage flows. Inside this coil is connected a steel armature of the meter movement. The more current is applied through the coil, the more the steel of the meter movement is drawn into the coil and this in turn moves the needle on the face of the meter to move further up the scale. If the coil polarity is reversed the magnetic field in the coil is reversed and the steel armature is driven in reverse. So instead of the meter movement moving up the scale it is driven to the zero end of the meter scale and it hammers up against the stop pin on the scale face.
