Air enters an adiabatic nozzle steadily at 300 kPa, 200 degreescelcius and 30 m/s
Air leaves at 100 kPa and 173 m/s
The inlet area of the nozzle is 95 cm^2
Determine the following:
(a) the mass flow rate through the nozzle.
(b) the exit temperature of the air.
(c) the exit area of the nozzle.

The gas constant of air is

The specific heat of air at the anticipated average temperature of450 K is
a) There is only one inlet and one exit, and thus
Using the ideal gas relation, the specific volume and the mass flowrate of air are determined to be





b) We take nozzle as the system, which is a control volume sincemass crosses the boundary. The energy balance for this steady-flowsystem can be expressed in the rate form as:

Rate of net energy transfer by heat, work, and mass = = Rate of change in internal, kinetic,potential, etc. energies (which come to 0 at steady state ) =



( Here no Q, W because potential energy = 0)

 0 =

 0 =

 0 = 1.02( ( Here we need to covert m/s tokJ/kg)

0 =

C

c) The specific volume of air at the nozzle exit is :



   0.63 =

Or alternative question:

Air enters an adiabatic nozzle steadily at 300kPa, 200Degrees Celsius, and 30m/s and leaves at 100kPa and 180m/s. The inlet area of the nozzle 80cm^2. Determine the mass flow rate through the nozzle, and the exit area of the nozzle. 

Use the following steps above just substitute 80cm^2 for area one in step A. Then use that mass to determine the exit area of the nozzle. 

How to add Omakase Links Crawler to Wordpress

Did you just add the Omakase Links Widget to your Wordpress site?

Many people are confused when Amazon says "To enable Omakase Links to work properly, your site must allow our spider (Mozilla/5.0 (compatible; >> AMZNKAssocBot/4.0)) to crawl your website. The crawl is needed in order to identify the content of your website and provide matching products. If you do not allow our spider to crawl your website(s) we will not be able to choose contextually relevant products, but will still display selected products from our product lines as chosen by Omakase Links' other techniques. Site owners can use their 'robots.txt' file to restrict the site content searched by the Omakase spider."

How do I do that with the 3.5.1 and up? I am currently using 3.8.1.

To add this crawler and allow you to crawl your site, you need to perform a few simple steps. 

1. Add the widget to your site, using the Amazon Associates Central. Clicking widgets and scrolling to the bottom to the Omakase Links Widget. 
2. Add to the area you would like this add to show.
3. Since the 3.5.0 update for Wordpress took away the privacy settings area in Wordpress and made it harder to find the robot.txt area, you need to download a plugin to make this simple to find again.
4. Download the WP Robots Txt Plugin. Link to Plugin
5. Upload this plugin by going to the sidebar of your Wordpress page to Plugins-Add New-Upload. (compress the folder you downloaded before upload)
6. When the Plugin is active, go to Settings-Reading in your Wordpress sidebar.
7. You will see an area called "Robots.txt Content"
8. Add this entry to your robots.txt file like this:

User-agent: Mozilla/5.0 (compatible; AMZNKAssocBot/4.0)
Allow: /

Check to see if you robot.txt file is working properly. By going to this URL

http://www.yourdomainname.com/robots.txt

If you see this file you added then you are good to go! Enjoy. 

The widget will now crawl your site use many techniques to determine what products to show on your page. Some of these techniques involves the Omakase system to process the text on your page and find products Amazon that your viewer is interested in.

Nike Sb Stefan Janoski

Nike SB Janoski (Dark Grey/Medium Mint)

The Stefan Janoski shoe in grey and mint is a great looking shoe. They skate as good as they look too. This is a low shoe with grippy outsole for great board control and flex. The shoe also has a reinforced ollie area and super comfy inside lining of the show. Definitely a shoe worth checking out if you haven't got yourself a pair already. 

Interesting Planetary Allignment

Planetary Alignment

Today is July 29, 2013 and there is a rare alignment that has been talked about for awhile now. The image charts the position of the planets and Saturn, Mars, the Moon, Pluto and Venus are aligning. There are relations between the forces of nature and the universe. Like the moon pulling tides and with the planets aligning there will be a significant influence on the equality on life. 

Towards the end of July, about this time, the chart shown to the right shows 7 out of 10 planets will be in positive configuration. Thus creating a large amount of healing energy on the as all of them are earth and water signs. The feminine forces is giving us forces of grace and love to atone for negative forces. 2013 is a big year for dramatic changes in the energy of the Earth. This year has high hopes for peace and success.
