Fluid Flow in a Duct of Varying Cross-Section Report

8. Create a graph: Select the GRAPH tab. Set the mass slider to 0 kg, and click Record to plot a point on the graph. Plot a point for each possible mass to create a graph showing the relationship between pressure and volume.

In conclusion, without the assistance of Poiseuille’s law, a patient with bronchial constriction would not get the adequate amount of oxygen to feed the tissues. Poiseuille’s law states that if the radius of a tube decreases by sixteen percent, the flow rate will decrease by half. In today’s modern medicine

rate of fall of an object was determined by its weight held that matter was constructed out

The objective of this exercise is to measure the pressure distribution across the surface on an aerofoil in a wind tunnel. The aerofoil is tested under several different Mach numbers from subsonic to supercritical. The purpose of measuring the pressure distributions is to assess the validity of the Prandtl-Glauert law and to discuss the changing chracteristics of the flow as the Mach number increases from subsonic to transonic.

The ± signs correspond to the acceleration of gravity and the sign is chosen according to the direction of motion; if the motion is upward the value (-g) is taken and if it is down, the value (+g) is taken.

What is the question asking you to identify? This question is asking to clearly identify centripetal force.

So, plugging in a value from the temperature/pressure data, and the value obtained for Subscript[\[CapitalDelta], vap]H, we

Though integration and manipulation of the elasticity equations with respect to the "z" the membrane forces can be found as:

Both the orifice and the Venturi meters produce a restriction in the flow and measure the pressure drop across the meter. The velocity of a fluid is expected to increase as the fluid flows from an open area, to a more constricted area. Assuming incompressible flow, a negligible height change, and steady state, Bernoulli’s equation can be simplified to show the correlation between the volumetric flow rate and the pressure drop. The equation for both meters is as follows:

1. Start Virtual ChemLab and select Boyle’s Law: Pressure and Volume from the list of assignments. The lab will open in the Gases laboratory.

Alternatively, it can also be explained by referring to the equation , where the k value is constant while the hydraulic gradient i defined by i = ΔH/L increases because the head difference ΔH is constant while the flow length L becomes shorter when it gets closer to the barrier wall.

This can be represented as : v2 = (elastic property / inertial property). Where the elastic property is usually the bulk modulus or Young's modulus of the medium, and the inertial property is the density of the medium.

Where Inflow from the tank), tank volume is (m3), % Full is the percentage of initial tank volume expressed as a decimal, and change in time is measured in seconds.

-The Reynolds number of this experiment was then calculated using equation (4) where c is the length of the aerofoil chord and is the dynamic viscosity of air.

the condition z1≠z2 is true if the two pressure taps are not horizontal (at different height).
