carrying a superheated steam at 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?

Aerobic vs Anaerobic Respiration Aerobic RespirationAnaerobic Respiration Diffen › Science › Biology Cellular respiration is the set of the metabolic reactions and processes that take place in organisms’ cells to convert biochemical energy from nutrients into adenosine triphosphate (ATP)‚ and then release waste products. It is one of the key ways a cell gains useful energy. Comparison chart Embed this chart Aerobic Respiration Anaerobic Respiration Definition Aerobic respiration uses oxygen. Anaerobic

Body image and Peer pressure The article I chose was about the body image and self-esteem of adolescents‚ along with why they are important. Self-esteem is all about how much you feel you are worth and how much you feel other people value you. Self-esteem is important because feeling good about yourself can affect your mental health and how you behave. On the other hand Body image is how you view your physical self‚ including whether you feel you are attractive and whether others like your looks

02 December 2012 1. Title and Author 1. The Effect of Extreme Temperatures on the Rate of Photosynthesis 2. Jeffrey Xia 2. Abstract A previous lab in which we conducted‚ tested whether or not the light intensity had an effect on the rate of photosynthesis. We concluded that light intensity did possess an effect on the rate of photosynthesis – the closer the experimental plant units were to the light source‚ the more experimental plant units exhibited the effect of gas exchange in photosynthesis

Goldfish and Water Temperature Goldfish and Water Temperature The subject of my observation is a goldfish that is kept in a 2 gallon fishbowl positioned on a window side table. I have noticed that the goldfish is more active in the earlier morning and later evening than during the afternoon hours. Because the table is near a window that faces northeast‚ the fishbowl receives direct sunlight during the time between eleven o’clock a.m. and four o’clock p.m. The goldfish activity decreases around

Blood Transfusion is commonly being ordered to patients who lost a great deal of blood due to a diseasecondition or an accident. It can also be ordered by the physician if the patient is to undergo an operation that would involve considerable blood loss. The following is a step-by-step checklist of things to do and other responsibilities to ensure proper blood transfusion and prevent any unwanted reactions and errors. 1. Verify the physician’s written order and make a treatment card according
