produces a greater velocity increase above the wing than below the wing. The greater velocity increases the pressure differential on a cambered airfoil. The greater pressure differential on the airfoil will increase the magnitude of the aerodynamic force. SYMMETRIC AIRFOIL Increasing angle of attack on any airfoil causes the area of the streamtube above the wing to decrease. This produces a greater velocity increase above the wing than below the wing. The greater velocity creates a pressure

changes its velocity. An object is accelerating if it is changing its velocity. People will occasionally say that a person is accelerating if he/she is moving fast. Yet acceleration has nothing to do with going fast. A person can be moving very fast and still not be accelerating. Acceleration has to do with changing how fast an object is moving. If an object is not changing its velocity‚ then the object is not accelerating. Sometimes an accelerating object will change its velocity by the same

Write the quantity equation and explain it. Money x Velocity = Price x Transactions Money x Velocity = Price x Output This theory seeks to explain how money affects the economy‚ and is based on the fact that money is demanded as a medium of exchange. We can say that price level is a function of the quantity of money in circulation. The transaction version of the quantity theory states that the changes in money supply other things remaining the same‚ brings a directly proportionate change in the

flows as stated in Graph 2.0 and Graph 2.1. It is proven that the higher velocity along the smooth bore pipe‚ the higher is the head loss of water. As shown in Table 3.0‚ when the Reynolds’ number increases‚ the value of pipe coefficient friction‚ f decreases along the decreasing stead laminar line. On top of that‚ there are energy loss from the water to the surface of the pipe and therefore‚ the temperature increases when velocity‚ flow rate and head loss increases respectively. The percentage difference

The pitot-static tube will be moved around to the centre of each cell so we can then take a reading for the pressure at that particular point‚ which can then be used to calculate the velocity across the matrix. This will enable me to determine how the pressure and flow performs in a non ideal situation by comparing the assumed volumetric flow rate at the pitot-static section with the calculated volumetric flow rate at the venturi.
