determination of the value for the molar heat of fusion of ice. The accepted value for the heat of fusion of ice is 6.01 kJ/mol. The percent error formula to be used is as follows: Percent error = theoretical value - experimental value x 100 theoretical value The percent error for trial 1 is 38%. The percent error for trial 2 is 42% and the percent error for trial 3 is 47%. 2. In order to do the calculations, you had to assume that all the heat lost by the hot water was…

the consequence of a decrease in the specific heat capacity of the solution compared to pure water. The specific heat capacity drops because the specific heat is lower for salt. Hence, when water is mixed with salt the specific heat value drops. In other words, it takes less energy to raise the temperature of the salt water by 1K than pure water. This means that the salt water heats up faster and eventually gets to its boiling point first. The heat capacity of NaCl has been found to be higher…

Evaporation: The rate of heat transfer in the evaporator is calculated using equations 10 and 11 Q_in=(εC)_evap (T_(in,evap)-T_evap ) (10) Where ε is the effectiveness of the evaporator, C is the capacitance rate for the air or chilled water passing through the evaporator. Tevap is the temperature of refrigerant in evaporator and Tin, evap is the temperature of the air or chilled water at the inlet of the evaporator. Equation 11 express Qin in terms of enthalpy. Q_in=m ̇_ref (h_4-h_1)…

Prepared by: Ahmed Alrahmani Prepared to: Dr. Maohong Fan Subject: Heat Transfer from Steam to Water Date: 11/01/2013 Summary: The objective of this experiment was to investigate the overall heat transfer ( Uₒ ) for the external heat exchanger at two different water circulation rates by using two methods “ Heating Liquids in Tank Storage ” and “ Corning Heat Exchanger “ . Briefly, the measurements were done by changing the volume flow rate between 40 lbm/min and 70 lbm/min for the first…

I found a mindful activity at http://www.pocketmindfulness.com/6-mindfulness-exercises-you-can-try-today/ called mindful observation. I focused on the grass in my backyard for 2 minutes. I felt extremely connected to the earth after this exercise because I felt that I was appreciating the natural world and all it has to offer. This is an exercise that I can incorporate into my daily life because it is simple and it doesn’t take much time but the lasting effect managed to stay with me all day.…

The article “Non-Profit News: Easy Ways to Lose Clients and Your Reputation” written by Dr. Warren Corson III was about how certain things, although they may seem insignificant can affect you and your clients in a negative way. An example would be focusing on making money. When a clinician is only focused on making money their clients may feel as if they are a meal ticket. Immediately asking to have clients pay their co-payment and fill out paperwork before asking the clients why they are there,…

1. James Harden- Houston Rockets Since being traded to the Rockets in 2012, James Harden leads all shooting guards in points scored, usage percentage, and made free throws. He’s established himself as one of the most dangerous offensive players in the entire NBA, regardless of the position. Harden is about as close to a lock as possible to average 25 points per game next season. From his incredibly high usage percentage, to his lack of a legit number two star around him; it’s almost a lock that…

For example, heat exchange network development from the embryonic stage or retrofit of current systems are one of the challenges of chemical engineering nowadays. Heat exchange network design might have various objective functions, such as minimum utility costs, minimum investment costs or minimization of the number of possible matches in the configuration. To address these challenges, optimisation tools and techniques can be applied. The problem needs to be decomposed…

Since the first galleys sailed the Mediterranean Sea, the world has seen a continuous evolution in respect to naval innovation. The addition of the steam engine to naval warships changed how ships not only operated but also revolutionized how ships were designed. Ship armor could now be thicker and heavier due to the propulsion that a steam powered engine allowed. Guns were also allowed to grow in size with the increased mobility of naval warships and the need to penetrate thicker armor.…

HVAC Technicians What is the importance of an HVAC technician? There are two reasons I chose this research topic, one of which being that throughout my High School career I have tried to place myself in as many different job fields as possible, or in as many different types of classes as possible.I have taken principles of business, which I may not have liked because we really did not have a teacher since he left at the beginning of the semester.I have taken drafting which was a great experience…
