atmospheric pressure is suspended from the ceiling of a large room. The steam temperature entering the pipe is 120 oC‚ and the air temperature is 20 oC. The overall heat transfer coefficient on the outer surface of the covered pipe is 10 W/m2.K. if the velocity of the steam is 10 m/s‚ at what point along the pipe will the steam begin condensing and what distance will be required for the steam to reach a mean temperature of 100 oC? Question 2: Consider a horizontal‚ thin walled circular tube

2. How is the colour related to surface temperature of the star? The correlation between the surface temperature of a star and its colour is due to the phenomena known as black body radiation .A star is a black body‚where it aborbs all the radiation falling upon it.AS its temperatures gets hotter thanits surrounding‚the star radiates its on electromagnetic radiation‚known as black body radiation. This radiation is distributed unevenly but contionously through multiple wavelengths of the electromagnetic

changes in enzyme function? Objective The objective of this experiment is to observe if changes in temperature will cause a disruption in enzyme function. Hypothesis If we add and boil enzyme in L-Dopa‚ then the color will become darker because the temperature will denature some of the enzymes. Variables Independent: Temperature Dependent: Color change Control: Time‚ Room temperature Jobs We were assigned different jobs to perform the experiment Janelee had two jobs because we were

We’ve all heard it before‚ "Exercise is good for you because...." Nowadays you can’t check out at the grocery store or do much of anything without being reminded that we mortal humans need to exercise. Still‚ we persist‚ procrastinate and eventually complain that we’re overweight‚ sick‚ dying‚ etc. Listen. Some exercise is better than none‚ more exercise is generally better than less‚ and no exercise can be disastrous. No one is asking for you to start a rigorous daily regimen‚ just do something

Pattern recognition is a useful tool for mathematics‚ mathematical visualization‚ and art. After a brief description of Bongard’s methodology in the field of pattern recognition‚ the author introduces the concept of colour modularity and evaluates how it affects pattern recognition classification. Combining Bongard’s methodology and colour modularity‚ the author attains a richer‚ more persuasive dynamic in pattern description and recognition of five- and ten-pointed star polygons.".

The Effect of Increasing Temperatures on the Enzyme Catalase Enzymes are proteins that help speed up chemical reactions inside your body and without enzymes‚ chemicals reactions in cells would be incredibly slow to a point where no activity at all takes place (Brawo press Inc‚ 2017). Enzymes speed up the chemical reactions by lowering the activations energy and they do this by binding substrates together in the correct orientation to react (Ernest Z‚ 2014). They are vital for life and serve a
