What is the relation between net thrust and gross thrust in a ramjet engine?
Net thrust in a ramjet engine is the actual useful thrust generated for propulsion, while gross thrust is the total thrust including the contributions from ram pressure. The net thrust is the difference between the gross thrust and the drag of the engine itself. The net thrust determines the actual propulsion force available for moving the aircraft forward.
What is the apparent mass in water?
The apparent mass in water refers to the apparent weight of an object when immersed in water. This weight is equal to the difference between the actual weight of the object in air and the buoyant force acting on it while submerged in water.
What are the 4 forces that act on aircraft and describe them?
1. Weight- caused by gravity pulling it towards the earth. 2. Lift- caused by a difference in pressure between the upper side and the underside of the wing. 3. Drag- caused by friction. 4. Thrust- caused by the engines pushing air in the opposite direction of travel.
What could be used to gather information about the difference in how much items weigh?
A scale or balance can be used to measure the weight of items and determine the difference in weight between them. By placing each item on the scale individually and recording the readings, you can calculate the difference in weight between the items accurately.
Does weight affect thrust?
Thrust is independent of weight. In straight and level flight thrust operates forward, drag operates to the rear, weight operates downwards and lift operates upward. For a rocket, traveling straight up (away from the center of the earth), drag and weight operate downwards while thrust operates upwards. --- The above answer appears correct (where "operates" is taken to mean "exerts force in the indicated direction") - additional discussion follows: (I am assuming we are talking about a rocket or an aircraft for the purposes of this answer. I am also assuming that by weight, we mean mass) The mass of a craft does not affect the thrust per se, that is, they are independent quantities as discussed below. Since the thrust is a function of the type (efficiency) of engine and the amount of fuel delivered per second, a formula expressing the thrust will not include the mass of the craft directly, hence the independence. However, of course, the thrust that a given craft can generate will be a function of the size of its engines, the type of fuel, and the amount of fuel delivered to the engine per unit time. Since the weight of the craft is partly determined by the size of the engine and the specific gravity of the fuel, there is a second order relationship between the weight of the craft and the thrust. The acceleration of the craft under thrust will of course depend on the thrust and the mass according to Newton's Second Law, F=MA, or in this case, the form A=F/M. PS: I'm not considering the relativistic realm either - you're on your own there!
What is the difference between thrust and pressure-?
what is the difference between thrust and pressure?
How is thrust different from force?
there is not much difference between thrust anf force...its just that thrust is the force acting perpendiclular to the surface thrust will always be either equal or greater than force.
What is the difference between an artesian spring and other spring?
The difference is that they are thrust up. They are not moving downhill because of gravity.
What is the relationship between the 4 forces of flight?
Lift is opposite of weight Thrust is opposite drag. When lift >weight plane climbs. If lift < weight you best find a place to land. If thrust> drag you accelerate. If drag>thrust you slow down. High and fast are your friends. Low and slow are out to kill you.
What is the relation between net thrust and gross thrust in a ramjet engine?
Net thrust in a ramjet engine is the actual useful thrust generated for propulsion, while gross thrust is the total thrust including the contributions from ram pressure. The net thrust is the difference between the gross thrust and the drag of the engine itself. The net thrust determines the actual propulsion force available for moving the aircraft forward.
Difference between thrust and reverse fault?
There is a slight difference. A thrust fault is a variety of reverse fault with a dip angle of less than 45 degrees.
What is the difference in weight between a rabbit and hippo?
Three tons is the difference between them
What is the weight difference between cast iron and aluminum 454 heads?
about a 75 # weight difference between both sides.
What are the four forces that act on an airplane in flight?
Lift, weight, thrust and drag.
What is the difference between a head tilt-chin lift and a jaw thrust?
difference between jaw thrust method and head tilt chin lift method ? which method is suitable for a patient with head or spinal injury
What is the difference in weight between platinum and gold?
The difference in weight between platinum and gold is that platinum is denser and heavier than gold.
What is the apparent mass in water?
The apparent mass in water refers to the apparent weight of an object when immersed in water. This weight is equal to the difference between the actual weight of the object in air and the buoyant force acting on it while submerged in water.
