Surface and center temperature of the mushroom, ambient humidity and temperature of vacuum chamber have been measured and recorded by the data logger inside the vacuum chamber (see Fig. 1). On the other hand, the control unit that records the pressure data is located outside the vacuum chamber (see Fig. 1). The measured data saved for each 10 seconds. Before starting the cooling, vacuum pump runs half an hour for stabilizing the system. Experiments carried out for three replicates and the…

Yeeeehaaaaaw! I land and nearly hit another pair of oldies and their puppy. I felt so bad. The puppy jumped out of its skin. Then reality kicks in when I return to the van where Keith is waiting, I'm no longer in a rush to catch up. The last of the energy seeps out when I attempt to lift my bike into the van. Now the cramp sets in. We arrive at the food haven, while me, Keith and Mitchell go to costa the rest go to that horrible place McDonalds. On the way back, Braden wanted to go through telly…

thermodynamics, a heat engine is a device/system that uses heat to do work, i.e. it converts heat or thermal energy to mechanical energy. 1.2 How does a heat engine work and its operating principles? For a heat engine to work, it must operate in cycles. Firstly, heat is added into the system. Let the heat added into the system be represented by [Qh]. After that process, some of the energy that were added into the system will be used to do work e.g the materials expanding or increasing in…

UVB’s 1. The sun shines on the skin. 2. The UVB light interfaces with a form of cholesterol in the skin called 97-dehydrocholesterol. 3. This is synthesized into pre-vitamin D3, which is immediately converted into vitamin D3. 30 minutes of midday sun in a bathing suit, and you’ve absorbed up to 20,000 IU of vitamin D. Whether you spend half an hour in the midday sun or take 2 10,000 IU of vitamin D3 in tablets, it’s then transported to the liver where it’s turned into D25 for storage. These…

Chotukool is a 45-liter plastic holder that can cool nourishment to around 8 to 10 degrees on a 12-volt battery. Forsaking the compressor innovation utilized as a part of local ice chests, it utilizes a thermoelectric or robust state cooling framework. It doesn't have a front opening entryway however opens from the top to guarantee that the greatest measure of cool air stays in the compartment when opened. The thought of Chotukool was conceptualized focused around the standards of Disruptive…

Water is an essential part of all living creature – human, Animals, plants etc. in olden days humans are depend on revers and ponds for fresh waters, but as industrialization goes on they are no more drinkable and fresh. So getting fresh water is a challenging job now a days in developing countries. As population is going on increasing, need for fresh water is keeps on increasing day by day. The available water on earth is limited to 79%, out of which only 2% water is directly available [1],…

Taking the Predictive Index exam was intimidating at first, but after completing the exam it was not so bad afterall. In the process of waiting for the results, finding out I’m a High C was not so shocking for me to discover. The behavioral factor in which a high C needs to function is patience which I agree is pretty accurate based off my PI exam as well as my daily behaviors, such as being patience in the workforce, public and with others around me. The primary motivational factors for a High…

Oscar Padilla Oscar Padilla Oscar Padilla 11-13-17 Mr. McMahon Period 1 Magnetic field strengths My science project is about homemade electromagnetic magnets and permanent magnets strength on heat and cold temperatures. I'm going to accomplish this by making three sets of electromagnets and permanent magnets in hot temperature, room temperature and cold temperatures to see how would they be affected by the different temperatures its put in. But the dependent variable is on the…

Abstract The purpose of this experiment is to determine the relationship between the temperature and pressure of air at constant volume which placed the Jolly’s bulb in water of different temperature. At the constant volume of the air in the Jolly’s bulb, the temperature and pressure of the air are measured and recorded throughout the experiment. The result shows that the pressure of the air in the Jolly’s bulb increases as the temperature rises, and the pressure decreases as the temperature…

straight pipe, a fully developed laminar assumption is satisfied under the condition that shape change is negligible. Numerical analysis technique the numerical analysis is performed by combining the governing equations related to the conservation of energy, conservation of mass and conservation of electrical charge to examine fluid distributions, heat transfers, mass transfers and electrochemical reactions. The assumptions used in developing the model are as follow: 1) Ideal gas law was…
