An Ammonia refrigerator is to produce 2 tonne of ice per day at -4°C from water at 20°C. if the temperature range in the compressor is between 25°C and -6°C‚ Calculate horse power required to derive the compressor. Latent Heat of ice = 80 kcal/kg‚ and specific heat of ice= 0.5 2. A compressor draws 42.5 m3 of air per minute in the cylinder‚ at a pressure of 1.05 kg/cm abs. It is compressed Polytropically pV1.3=C to a pressure 4.2

comprehension or as I like to call it creativity. Funny Enough‚ I use the ocean‚ something so serene and effervescent to describe my annual quarter life crisis. Unconciously however‚ that must be no mistake‚ seeing that Water will be the theme of the experiment I will be working with. I’m still a little skeptical as to how I chose Water . There was no real inspiration‚ or interest on such force but rather an intuition that drove me to further explore this element. Perhaps an unconscious inclination

I have had to learn the differences between screen printing and heat transfers. At first‚ it was hard to figure out which one would be the best for our customers. When I finally got the hang of helping our customers in the front‚ it started to get easier. There are many things that should be considered when deciding on what method you should use. If you need a job done in a hurry‚ your best option would be heat transfer. Heat transfers can typically be done in about two hours‚ depending on size

float. Any object with density more than that will sink. Carbon dioxide‚ or CO2‚ also played a big role in this experiment. Many soft drinks contain CO2. Studies show that Sierra Mist had the most carbonation out of most soft drinks. There was a lot of carbon dioxide in the soda. That was the reason the raisins would float up and down. There were many purposes to this experiment. One purpose was to teach us about density when we saw how the raisins floated to

The details of this case may offer further insight into the admissibility of experimenting on children as long as there is parental consent and the consenting parents are fully aware of all details of the experiment.

Social psychologist‚ Stanley Milgram of Yale University conducted a controversial and influential experiments on study of the effect of punishment on learning. Nearly 1000 people participated in Milgram’s 20 experiments. The participants assigned to be a learner and a teacher. Milgram created an electric ’shock generator’; it ranged from 15-450 volts. The teachers were given a task to teach and then test the learner on a list of word pairs. For the first wrong answer‚ the teacher will flip the switch
