Minimum drag can be achieved when the object's shape is streamlined and smooth, the surface is free of imperfections, and the object is moving at the optimal speed for that specific shape and conditions. Reducing drag is essential for improving efficiency and performance, especially in industries like aerospace and automotive engineering.
What else can I help you with?
How can drag be reduced when flying a plane?
Drag can be reduced when flying a plane by minimizing air resistance. This can be achieved by reducing the aircraft's speed, using streamlined designs, retracting landing gear, and keeping the surfaces clean. Additionally, flying at higher altitudes where air density is lower can also help reduce drag.
Does a hydrofoil increase max speed?
Yes, a hydrofoil can increase the maximum speed of a boat by reducing drag caused by the hull interacting with the water. The hydrofoil lifts the boat out of the water, reducing drag and allowing for higher speeds to be achieved.
Minimum gibbs free energy is NOT attained by a semipermeable membrane. True or false?
True. The minimum Gibbs free energy is not attained by a semipermeable membrane, as the membrane itself does not participate in any chemical reactions that could lower the system's overall free energy. The minimum free energy is achieved through chemical reactions occurring within the system.
Terminal velocity is achieved when an object?
Terminal velocity is achieved when an object falls through a fluid (such as air) at a constant speed due to the balancing of the gravitational force pulling it down and the drag force pushing it up. At this point, the object's acceleration becomes zero because the two forces are equal in magnitude but opposite in direction.
Is profile drag of an aircraft also known as skin drag?
no, its part of profile drag. due to roughness, skin friction increases which affects the drag. drag can also be increased by changing the shape or by introduction of active/passiv flow control devices like vortex generators.
How can drag be reduced when flying a plane?
Drag can be reduced when flying a plane by minimizing air resistance. This can be achieved by reducing the aircraft's speed, using streamlined designs, retracting landing gear, and keeping the surfaces clean. Additionally, flying at higher altitudes where air density is lower can also help reduce drag.
What is the minimum value of sum of a positive real number and its reciprocal?
This minimum is achieved when the number is 1 (and the reciprocal therefore is also 1).
The minimum altitude required for a satellite to avoid significant aerodynamic drag is?
200 miles(:
What is the minimum unique array sum that can be achieved?
The minimum unique array sum that can be achieved is when all elements in the array are different, resulting in the sum of the array being equal to the sum of the first n natural numbers, which is n(n1)/2.
When water skiing if the boat was going fast would it create more drag or less drag for the skier?
The drag vs Speed graph will be a curve, with it's minimum at some speed greater than zero. At slow speed, the skier needs to angle the sji at a high angle to the water in order to produce enough lift to stay upright. This is known in Aerodynamics (and, I imaging, Hydrodynamics) as Induced drag. As the speed incearses, the skier can angle the ski at a lesser angle, thus reducing drag. However, as speed increases further, the frictional and drag forces associated both with the movement of the ski on the water, and the skier through the air increase ("Form and Parrasite" drag). The sum of all drag will reach a minimum where induced drag has reduced, but the other types of drag have yet to significantly increase. Drag will be greater at EITHER a slower OR faster speed than this minimum figure.
What is mellinium mode on a paintball gun?
It is a ramping mode that, as a minimum trigger pull speed is achieved, the marker rolls over into fully automatic for as long as minimum bps is kept.
Does a hydrofoil increase max speed?
Yes, a hydrofoil can increase the maximum speed of a boat by reducing drag caused by the hull interacting with the water. The hydrofoil lifts the boat out of the water, reducing drag and allowing for higher speeds to be achieved.
Why did the Wright brothers achieve in flight?
I can tell you HOW: they used the forces of flight; lift, thrust, drag, and gravity That's pretty much WHY they achieved flight
Who designed the first airfoil?
In 1939, Eastman Jacobs at the NACA in Langley, designed and tested the first laminar flow airfoil sections. These shapes had extremely low drag and the section shown here achieved a lift to drag ratio of about 300.
By 1880 nearly three quarters of black southerners became what?
They became tenant farmers and achieved minimum autonomy through sharecropping.
How does downward forse help an Indy car?
When drivers always say they want more downforce in the turns, what they are asking for is maximum stickiness in the corners with minimum drag on the straights.
How much does a drag racer weigh?
In Pro Stock drag racing, the minimum weight for a car, including the driver, is 2,350 pounds. The NHRA Pro Stock racing champion for 2013 was Jeg Coughlin, and the person with the most NHRA Pro Stock wins is Warren Johnson with 97.
