Velocity Distribution of a Circular Air Jet

However, in this experiment the error can be considered as negligible
A fan supplies air to a nozzle, which can provide a circular uniform jet of air. The nozzle is 30 mm in diameter. The velocity distribution in the jet is measured using a pitot static tube. The Pitot-static tube can be traversed across the jet diameter and also across its length by sliding the support against a millimeter scale to record its position. The pitot static tube is connected to an inclined manometer.
7.2 Measure the air velocity at points along the horizontal diameter at x=2D. Plot the variation of v with y as you take your readings. Use your judgment over how many points you need, ensuring that you locate the endpoints at the edge of the jet
7.4 The graphs should be symmetrical about the centerline. Decide for which graph, which value for y is at the center so that by subtraction, it is possible to plot V against radius r, measured from the centerline of the jet.
The pressure in the center of the jet is higher at the point of origin. The pressure stabilizes further away to the point of origin to match the surrounding pressure and hence the jet spreads out as it flows in order to reduce its density. ...Show more


To investigate the velocity distribution of a circular air jet at a number of stations along the length, to reveal how a uniform jet mixes with its surroundings by using a pitot-static tube to measure the velocity of the fluid in the jet.
The pitot static tube measures two pressures, P0 and P, the Total and Static pressures respectively…

Operational Amplifiers
All op-amps have two inputs connected in a differential mode, so that output voltage is Vo= A(V+ - V-) where V+ is the voltage at the non-inverting input and V- is the voltage at the inverting input. A is the open loop gain of the op-amp. In our case the Vo=A [15-(-15)] = A(30).

Calcium as Second Messengers
Binding of a ligand to a single receptor at the cell surface may end up causing massive changes in the biochemical activities within the cell (Kimball, 2006). There are three types of second messengers: cyclic nucleotides like cAMP (cyclic adenosine monophosphate); IP3 ( inositol triphosphate) and DAG ( diacylglycerol); and Calcium ions.

3. When there is no flow and the rocket's fin is disturbed, say, by a poke with a rod, oscillation or vibration occurs, which is damped (reduction of amplitude caused by structural resistance) gradually over successive vibration cycles. 7. At speeds above this critical condition (UF), any small accidental disturbance of the fin from a gust of wind can serve as a trigger to initiate an oscillation of great violence that will rip the fin right off the rocket causing an unstable flight condition.
