Heat Transfer Through Jacket Objective The objective of this example is to analyze heat transfer in a pilot plant using simulation models. The first step is to use pilot plant data to calculate heat transfer parameters. The second part involves using simulation models to examine the trade-off between jacket parameters and heating times. Process Description Assumptions: The stirred tank is assumed to be perfectly mixed. The contributions of agitator work‚ heat loss to environment

------------------------------------------------- ASSIGNMENT 1 1. A rigid tank with a volume of 1.8 m3 contains 15 kg of saturated liquid vapor mixture of water at 90oC. Now the water is slowly heated. Determine the temperature at which the liquid in the tank is completely vaporized. Also‚ show the process on a T-v diagram with respect to saturation lines.

Right to self-determination All of us have the right to self-determination. In a far view‚ right of self-determination simply means that all people have the right to freely determine their political status and pursue their economic‚ social and cultural development. This merely involves the freedom to acquire and dispose of property and wealth generally as the person choses. Right to self-determination is an unalienable right; the government can’t take the right away. The specific right applies

Determination of pKa James McDuffie ABSTRACT: In this lab‚ the pKa of unknown solution #4 was measured Introduction: This lab focused on the equilibrium constant‚ Ka. Ka is associated with chemical properties of acids. The equivalence point will be reached once the moles of OH- equal the moles of HA and once this point is reached‚ the PH changes very quickly. With the results‚ a titration curve should be produced. Experimental Section Materials and Methods: A buret with NaOH solution

Determining the Enthalpy of a Chemical Reaction All chemical reactions involve an exchange of heat energy; therefore‚ it is tempting to plan to follow a reaction by measuring the enthalpy change (∆H). However‚ it is often not possible to directly measure the heat energy change of the reactants and products (the system). We can measure the heat change that occurs in the surroundings by monitoring temperature changes. If we conduct a reaction between two substances in aqueous solution‚ then the

The Importance of Determination Everyday people face challenges‚ but it is important that one does not give up‚ and to keep trying until they successfully overcome the obstacles that stand in their way. “Mother to Son” by Langston Hughes and “Still I Rise” by Maya Angelou are two different works written by two different authors yet they both convey the same message. Together‚ the two authors stress the significance of pushing harder when faced with conflicts rather than simply giving up. Using

Crash Course in Density Jonathan Cerreta Chemistry As flight 143‚ a twin engine 767‚ was passing over Red Lake on its was to Edmonton‚ Canada‚ the left front fuel pump warning light went on. There were a few possibilities for this to happen‚ such as the fuel pump failing‚ a fuel line clogging‚ or a empty fuel tank. The former two were easily dealt with‚ since the plane could fly without one fuel pump. However‚ the last possibility was horrifying. After a few minutes‚ the second fuel pump
