Comparing fluid flow of smooth and rough pipes

Most common housings for this turbo are 0. This is a good turbo if you have an automatic, and can be daily driven.

For an example of an 'Open' EEI task sheet, click here. Photovoltaic power generation employs solar panels comprising a number of cells containing a photovoltaic material. The Australian Government provides incentives for the use of PVs for both domestic and industrial use you can save money, and save the environment.

Solar photovoltaics generates electricity in more than countries and, while yet comprising a tiny fraction of the GW total global power-generating capacity from all sources, is the fastest growing power-generation technology in the world.

Between andgrid-connected PV capacity increased at an annual average rate of 60 percent, to some 21 GW. A good EEI would be to measure current as a function of the angle of incidence of sunlight all within a short period of time eg 30 minutes ; measure current when collector is perpendicular to rays during the day how should that go?

But maybe you'll need to consider more than current; perhaps the power output is more important. If so, you could put a load on the circuit resistor and measure V and I.

In the method shown below, Moreton Bay College students are measuring the effect of angle on the flow rate hence power output of a electrical water pump.

This was Year Energy output of a solar panel II You could also investigate the effect of shade on the output of a panel.

In this photo, students are using layers 1, 2, 3 etc of shade cloth. It would also be interesting to see the effect of light of different wavelength to see if the solar cells are sensitive to all wavelengths.

You could use coloured cellophane - but then that reduces intensity and not all coloured cellophane has the same percentage transmission. This limitation makes photovoltaic cells an unreliable source of power for unattended or remote devices, such as solar-powered traffic signs or NASA's Mars Rover.

For large-scale solar plants to maintain their maximum efficiency, the photovoltaic cells must be kept clean, which can be a challenging task in dusty environments. One good EEI would be to investigate the effect of dust on the solar panel.

This is a harder EEI than the two above. It involves setting up a solar panel a short distance from an incandescent bulb eg 15 cm and adding controlled amounts of "dust" eg bentonite clay powder, fine sand, icing sugar to the face of the panel spread evenly.

It is a good idea to adjust the panel so it is working at maximum power. Do this by setting up the circuit on the left below, using either a variable resistor or fixed resistors that can be varied from 0 ohm to ohm. Plot a graph next figure to see the maximum power point.

Then add the bentonite 0. A good article is in Physics Education, V45, Septemberpage When we derived a formula for predicting flow rate from pressure dropped by a orifice or venturi tube or, we had to make many assumptions, chief among them being a total lack of friction (i.e.

no energy dissipated due to friction) within the moving fluid and perfect stream-line flow (i.e. complete lack of turbulence). Suffice it to say, the flow formulae we have discussed (previous topics) so.

A. A4 (size) A common ISO A-size of about /4 by /4 inches or x mm. For all sizes see International Paper and Board Sizes. Abaca A fiber also known as manila hemp or manila fiber, prepared from the outer sheath of the stems of manila. International Journal of Engineering Research and Applications (IJERA) is an open access online peer reviewed international journal that publishes research. “Galvpatch®” is a two part solvent free organic epoxy containing % solids of which >80% is micronized zinc by mass. “Galvpatch®” was developed for the approved limited repair to both hot dip galvanized and flat sheet galvanized steel in accordance with “SANS ″.

This means the same wall can be both smooth and rough depending on the fluid’s velocity. Experiments have proven the pressure loss along a pipe with laminar flow is proportional to the velocity (p ∝ V) where as for turbulent flow the pressure loss is proportional to the square of the velocity (p ∝ V2).

The pipe flow probe compared the fluid flow of smooth and unsmooth pipes of changing diameters.

The force per unit area bead across the pipes was recorded to happen both the clash factors and Reynolds Numberss. A Moody diagram was plotted comparing the clash factor versus the Reynolds figure.
