  • Lab Report: Moolar Volume Of A Gas At STP

    volume of a mole of H₂(g) is at STP by using gas laws. The hypothesis for the experiment is that if H₂(g) is produced at RT and STP, Avogadro’s law can be used to experimentally determine the amount of H₂(g) because equal gases at the same pressure and temperature have the same amount of particles. In order to find the molar volume, hydrogen gas was produced in a eudiometer tube by reacting magnesium and hydrogen chloride. The results showed that the molar volume of H₂(g) was 27.5L per mole of H₂(g). It was concluded that the molar volume of a gas can be experimentally determined by using gas…

  • Atrium Fire Case Study

    beginning of fire , the smoke moves to outside and the atrium, and air from ambient and the atrium moves inside the fire floor at the same time from the 2 vents. Figure 2.8 shows the velocity direction at the vents. At the top of the vents, because the smoke in the fire floor is lighter than the air in the atrium and ambient because of the high temperature, pressure difference between the fire floor and atmospheric pressure is larger than at the lower place of the vents. At the bottom of the…

  • Molar Volume Of Gas Lab Report

    purpose of the lab was to do an experiment to determine the molar volume of hydrogen gas at standard temperature and pressure, or STP. To start the experiment, a beaker was filled with water and then a cage was created with a copper wire. A piece of magnesium was cut and placed inside the cage in order to keep the reaction going until all of the magnesium reacted with the hydrochloric acid. The eudiometer tube was filled with 15 mL of hydrochloric acid and water and then plugged with a one-hole…

  • Malpractice Case: Alterations In The Emergency Department

    resuscitation was instituted without success, and Cindy Black was pronounced dead. Departure from professional standards of nursing care: In every nursing malpractice case the defendant nurse's conduct is measured against that of a reasonably prudent nurse under the same or similar circumstances. Departure from the professional standards of nursing care for the first admission to the emergency department included the following deviations: · Failure to assess Cindy Black comprehensively upon…

  • The Importance Of Climate And Climate

    changes, the easement conditions will change is the climate alteration which is shown by great climate and also by fine climate. Mankind has different reactions to these changes too. But the meaning of human welfare conditions is situations that are proper at least for 80% of individuals when our point of view ends to the temperature. In another word, in that conditions human never feel chill or hot. Some researchers know the neutralization of temperature phrase as the more exact explanation…

  • Performance Analysis Of Centrifugal Blower

    discharge pressure. Blower is also known as fan, but, traditionally, blowers do not discharge air at low pressure as some fans do. Figure 1.6 – CENTRIFUGAL BLOWER Dryers use centrifugal blower, where air is radially discharged from the impeller, (or fan wheel), so turns 90° from its inlet to its outlet (Figure 1.6). Air enters the impeller at the blade inlet with an absolute velocity of v_1. As the fluid elements flow through the blade passage, they accelerate. Moreover, a guiding pressure…

  • Jess's Case Study: The Importance Of Catheter Replacement In Medical

    breathing, Intermittent positive pressure ventilation (IPPV) was performed until she began to breathe by herself. Jess was seen as a geriatric patient recovering from more than one major surgical procedure in one day and so intensive nursing care had to be maintained to a high standard. She would be experiencing a large degree of pain after the procedures and be less mobile; whilst it would be beneficial for Jess to be moved regularly this was not always the case. I monitored and observed her…

  • Heat Exchanger Analysis

    The heat exchanger design is an optimization engineering problem, to approach the best solution for sizing and selection of a heat exchanger and also to analyze its thermal performance. A properly sized heat exchanger should incorporate excess capacity to account for fouling that will occur during operation but too much oversizing results in higher manufacturing and installation costs. The most appropriate metric to describe the performance of a heat exchanger is its thermal capacity, which is…
