What is Mach buffet?
Thus far, only the Mach buffet that results from excessive speed has been addressed. It must be remembered that Mach buffet is a function of the speed of the airflow over the wing-not necessarily the speed of the airplane. Any time that too great a lift demand is made on the wing, whether from too fast an airspeed or from too high an angle of attack near the MMO, the "high-speed" buffet will occur. Interupted airflow over the wing which can be caused by high speed in thin air, high angle of attack , high wing loading, or G forces, all of which disturb the airflow over the wing. It is not the speed of the airplane but the speed of the air over the wing.
Why are winglets put on a planes airfoil?
Winglets are fitted to the tips of aircraft wings to increase the lift efficiency of the wing. As the airflow passes over the wing shape, the air going over the top of the wing has further to travel. The air flowing over the wing near the the fuselage body up to about 3quarters of the way towards the tip of the wing has to travel up and over the wing, thus creating the lift. Air, as with water will choose the path of least resistance, so airflow near the wing tip starts to go over the top of the wing but then" slips off " to the side meaning that the end section of the wing produces little or no lift. The winglets are there to stop the slipping off effect by blocking the airflow from slipping off. This means that lift is created along the full length of the wing.
What does the evaporator do in a refrigeration system?
An evaporator in a refrigeration system works by passingwarm air over it's coils. The warmth of the air heats theliquid refrigerant inside, causing it to boil into gas. Atthe same time, the air looses it's heat and turns cold.
Why do air conditioner coils ice up when the refrigerant is low?
Any refrigeration or AC evaporator coil has a tendency to ice up when they get cold. Water condenses on the coil when the air is cooled. That water can then freeze. If an AC system is operating correctly it will cool the air and eventually when room temperature reaches the set point the AC unit will turn off, this give any ice that has formed on the evaporator coil a chance to melt. If the system is low on charge, the room may never reach the set temperature and therefore will not shut off. The ice will continue to build on the evaporator coil until it is completely iced over. A dirty evaporator coil can cause this as well, so change your filters often. Another possibility is the ac system has to be matched to room or house size. Too small and too large a system will both cause you problems.
Water boils at alower temperature on the hills because there is a decrease in air pressure on the hills?
Because of the rounded nature of the hills, they function very much like the upper surface of an aircraft wing when there is an airflow (wind) over them. This leads to lower pressure on the hills themselves (in an aircraft this would cause lift). This lower pressure makes it easier for for water to turn from a liquid to a gas (less energy is required for the phase change to occur) and the water boils at a lower temperature
What does the refrigerant do in the evaporator?
An evaporator in a refrigeration system works by passing warm air over it's coils.
What is bourgeoisie's solution to over production?
Lowering prices so that they can compete with their competitors would be my guess
What does the evaporator do in the refrigeration system?
An evaporator in a refrigeration system works by passing warm air over it's coils.
What is the advantage of multiple effect evaporators over single effect evaporator?
energy is economised since the evaporator at alower pressure heats the following effect
How many types of refrigerator evaporator are there?
over 10,000 refigerators
What wrong with your AC at home if it running but not blowing?
evaporator frozen over
The is the air passing over the evaporator has the greatest effect on the film factor?
Velocity
What is an evaporator solenoid and what does it do?
It is a device that cycles the compressor depending on the line pressure coming out of the evaporator. Some vehicles have the switch located over on the high "condenser" side of the system.
What is affected by an airplane's speed?
Airflow ans lift over the airframe is affected by the airplane's speed.
What has the author J M Nicholls written?
J M. Nicholls has written: 'The airflow over mountains'
What advantages does a thermostatic valve have over a capillary tube?
Thermostatic expansion valve allows more refrigerant into the evaporator coil during a hot pulldown it allows the evaporator to reach peak performance faster
Why do planes dive?
Planes dive to get airflow over the wings where the air is thicker. The thicker the air the better the airflow. Planes also dive in stall. Stall is where the plane can no longer fly areodynamicly. Hope this helped.
