Experiment 9 and 10: Volumetric/Vinegar Analysis Abstract: The goal of the experiment that was conducted was to figure out both the molar concentration of NaOH and the standard mole ratio of the NaOH solution. In order to find the concentration of the NaOH solution‚ volumetric analysis was used. In volumetric analysis‚ a titration mechanism was utilized in order to find the reaction that the base will end up having with KHC8H4O4

objective of understanding how various factors may have an influence on blood flow rate. These factors include the effect of blood vessel radius‚ the effect of blood viscosity‚ as well as the effect of blood vessel length‚ and the effect of blood pressure. This better understanding of cardiovascular dynamics was achieved with PhysioEx 9.1. Hypothesis: Hypothesis- Activity 1: Studying the Effect of Blood Vessel Radius on Blood Flow

experiment we were exposed to a variety of important concepts related to quantitative experimentation‚ including the proper use of glassware‚ and analytical balances. b. How did you do it? Briefly describe the procedures in 1 sentence. We calibrate a volumetric pipet and flask. We also calibrated a beaker and 50 mL buret. We also calculate the difference between the expected density and density obtained by our team. c. What happened? Briefly give the result (or results) of the experiment in 1 sentence

Part A- Additive Volumes First‚ obtain a dry 10 mL volumetric flask that includes a stopper with it and weight on a digital scale. Be sure to get the mass at the closest milligram. Then‚ pour DI water to the calibration mark of the flask. Place the stopper back and weigh it again on the same digital scale. Once recorded‚ it is okay to pour this water down the drain. Observations: Mass of Empty Flask Mass of DI Water Filled Flask 15.114 g 25.048 g Now‚ put 100 mL of ethanol in a beaker and

For factor conversion in the reactor‚ PFR showing the highest conversion value‚ which is up to 90.18%‚ followed by 3-stages CSTR which is 75.06% and lastly single stage CSTR which is 58.60%. The reaction rate constant and rate of reaction has been calculated and compared with these 3 types of reactors. For 3-stages CSTR‚ the Damnköhler (Da) number is calculated to estimate its highest conversion the reactor can achieved. The deep information is being discussed in

INTRODUCTION The measurement of fluid flow is very important in our daily life from measurements of blood-flow rates in human artery to the measurement of liquid oxygen in a rocket. In this experiment‚ students are to adapt to various ways to measure the flow of essentially incompressible fluids by using the flow measuring apparatus. Students will also be able to understand the application of Bernoulli’s equation in this experiment. The flow is measured by using a venture meter‚ an orifice meter
