Experiment 3: Fluid Flow Friction and Fitting Loss Objective To determine the pressure or head loss in different diameters pipes‚ joints and valves Theory Pipe flows belong to a broader class of flows‚ called internal flows‚ where the fluid is completely bounded by solid surfaces. In contrast‚ in external flows‚ such as flow over a flat plate or an airplane wing‚ only part of the flow is bounded by a solid surface. The term pipe flow is generally used to describe flow through round pipes

Fluid Balance Explain in detail the fluid compartments of the body‚ including distribution of fluid and electrolytes within each compartment and the movement between compartments. In the average person water constitutes 60% to the total body weight.: 42L in a 70kg individual. 40% is intracellelular fluid‚ while remaining 20% is extracellular. The extracellular fluid can be divided into plasma (from intravascular compartment) and interstitial fluid intracellular fluid (28 L‚ about 35% of lean

complete. Chemists also need to monitor how acidic or alkaline waste solutions from industries are before they are pumped into rivers or the sea. Regulations are strict as wastes or effluent that are too acidic or too basic can be harmful to the environment. • • Many people who are not chemists use indicators for: The water in aquariums needs to be tested. Fish are sensitive to changes in their water. If the water becomes too alkaline or too acidic it will kill fish and plants. The water in

Effects of Temperature and Cofactors on Enzymatic Reactions “I pledge that no unauthorized assistance has been given or received in the completion of this work. Experiments described were performed by me and/or my lab group and this write-up is entirely my own creative work.” X________________________________________ Introduction Enzymes are protein molecules that speed up the rate of reactions by reducing the activation energy of a reaction. They act as catalysts in reactions‚ increasing

Premium Enzyme Catalysis Chemical reaction
Name: Date: 03/20/2013 Lab: # Purpose of this lab: To test for the effects of temperature on catalase activity. Introduction: Enzymes are proteins that act as catalysts and help complex reactions to occur everywhere in life. Enzymes affect a chemical reaction by acting as a catalyst‚ which is to say‚ it speeds up the reaction. However‚ extreme ph and temperature hinders enzyme function. Optimal activity of an enzyme is the optimal environment that an enzyme requires to function
