Fluid Meter and Tray Hydraulic Experiment Essay

Purpose: To become familiar with the International System of Units and common laboratory equipment and techniques. To learn how to determine volume, mass, length, and temperature of a wide variety of items. To learn how to calculate density and concentration of dilutions.

Vial number one had trouble staying down but my group held it under until finally they were able to get it to stay underneath the water. The rubber band could now be removed from the tray. The respirometers were in the water for a timed three minutes to allow them to equilibrate. After the three minutes was up the initial level of oxygen that entered the pipet was recorded in our lab books. After this data was found and recorded we were finally able to begin the actual experiment testing.

The administration of a small amount of fluid is thought to have minimum adverse effects in even non-responders. Muller et al reported that a rapid administration of 100 mL fluid induced a greater than 10% increase of subaortic VTI by Doppler echocardiography, which subsequently predicted a 15% increase in VTI after a 500 mL of fluid administration in mechanically ventilated and sedated ICU patients with acute circulatory failure5. Guinot et al demonstrated a greater than 7% SVfc measured by thoracic impedance cardiography after 100 mL of fluid administration was a good predictor of a subsequent increase in SVfc in response to a 500 mL fluid loading in spontaneously breathing patients under spinal anaesthesia6. Therefore, the mini-fluid challenge can be a clinically useful diagnostic method to predict fluid responsiveness in either mechanically or spontaneously ventilated patients. The present study also showed the relatively high (r = 0.77) correlation coefficient between SVfc3 and SVfc10, suggesting that the greater the increase in SVfc3, the better the fluid responsiveness. SVfc3 greater than 5.8% measured by transthoracic echocardiography also predicted fluid responsiveness in mechanically ventilated anaesthetised dogs. All these results support the ability of the mini-fluid challenge to predict fluid responsiveness based on SVfc. However, the assessment of SVfc is challenging in routine practice because it requires special and expensive equipment. Therefore, an alternative simple method to assess SVfc would be

Procedure: Using distilled water, premeasured containers and objects determine displacement of fluids and density of objects. Use ice and heat measure temperatures in Celsius, Fahrenheit and Kelvin.

Controls- The control in this experiment was very important because if it was not contained, then the data would have been faulty. It was very difficult to keep

We first started this experiment by obtaining twelve 15ml test tubes, in which we placed in a rack and labeled each with what

What were your controls for this experiment? What did they demonstrate? Why was saliva included in this experiment?

The next step in this lab is to rinse the Erlenmeyer flask with distilled water down the drain and then repeat the experiment, this time adding 10 ml of 0.10M KI and 10 ml of distilled water to the flask instead. The flask should again be swirling to allow the solution to succumb to the same temperature as the water bath and once it has reached the same temperature, 10 ml of 3% H2O2 must then be added and a stopper must be immediately placed on the flask and recording should then begin for experiment two. After recording the times, the Erlenmeyer flask must then be rinsed again with distilled water down the drain. After rinsing the flask, the last part of the lab can now be performed. Experiment three is performed the same way, but instead, 20 ml of 0.10 ml M KI and 5 ml of distilled water will be added and after the swirling of the flask, 5 ml of 3% H2O2 will be added. After the times have been recorded, data collection should now be complete.

Abstract: This experiment introduced the student to lab techniques and measurements. It started with measuring length. An example of this would be the length of a nickel, which is 2cm. The next part of the experiment was measuring temperature. I found that water boils around 95ºC at 6600ft. Ice also has a significant effect on the temperature of water from the tap. Ice dropped the temperature about 15ºC. Volumetric measurements were the basis of the 3rd part of the experiment. It was displayed during this experiment that a pipet holds about 4mL and that there are approximately 27 drops/mL from a short stem pipet. Part 4 introduced the student to measuring

The Lab One was done on Laboratory Techniques and Measurements. The first experiment with my Lab partner; we got opportunity to experiment how to conduct measurements in length by using metric conversion. We started in cm units and changed into mm by x10, and moving decimal point x1 to right. To find in meter we moved from cm to meter two decimal points to the left or double check our self divided by 100 and all records in data table 1. The second experiment was to measure temperature of how cold and hot tap water can be by using thermometer in Celsius units. From this experiment, gained knowledge that tab water doesn’t boil to 100 Celsius related to containing different

This experience consisted of 20 subjects from Woden plaza varying of age and gender. It also included one student who was going to conduct the experiment.

The start of the experiment consisted of filling up four beakers with de-ionized water to 150 ml. After the beakers were filled to the appropriate amounts they were then labeled with the

Because of safety circumstances, it is very important to control pressure loss through pipes in order to ensure a process plant to operate in a safe way. To design a safe plant operation, pressure loss across the process plant should be taken into account and it can be manageable by making changes in flowrate of the fluid. The aims of this experiment are to measure pressure drop across different pipes,fittings, venturi meter and orifice plate, to figure out momentum change of air due to jet impingement on a flat plate and finally, to discuss differences between practical measurements and theoretical predictions.
