ABSTRACT On the past two weeks‚ I have done an experiment on hydrostatics‚ or is also known as fluid statics (fluid at rest) within the fluid mechanics field of study. This condition explains that in a stable condition‚ the fluid is at rest. The use of fluid in doing work is known as hydraulics‚ and the science of fluid in motion is known as fluid dynamics. INTRODUCTION The natural nature of fluids are they cannot remain stationary under the application of shear stress. However‚ fluid

Lab Report Density Name: Period: Problem How do you calculate Density? What units did you use for volume‚ mass‚ and density? When the cubes are placed in water which one will sink 1st? What is the ranking of the cubes lightest (1) to heaviest (10)? Is it true that the cube with the most mass will have the most density? Hypothesis I think the 1st cube was aluminum I think the 2nd cube was steel I think the 3rd cube was brass I think the 4th cube was copper I think the 5th

Impurity Lab Report Aim: To find out the difference of the boiling point and melting point when adding impurity (salt) to water. Diagram: Method: 1.Set up the apparatus as shown in the diagram 2. Get a known amount of ice in the beaker (half full)‚ and a known amount of salt in another beaker 3. Measure the temperature (melting point) of the ice without adding any impurity (salt). 4. Measure the temperature (melting point) of the ice after adding the salt into the beaker. 5. Heat up

Introduction:- The primary objective of this experiment is to determine the concentration of an unknown copper (II) sulphate solution. You will be using the colorimeter. In this device‚ red light from the LED light source will pass through the solution and strike a photocell. The CuSO4 solution used in this experiment has a deep green color. A higher concentration of the colored solution absorbs more light (and transmits less) than a solution of lower concentration. [Content Standard B- Structure

facultative aerobe prefers oxygen but it is not necessary for growth. Many of these microorganisms will grow at the top of the tube‚ but will also be dispersed throughout as well. B. Discuss the temperature requirements of the organisms (you grew) in this lab. Both Staphylococcus epidermis and Lactobacillus acidophilus are mesophiles. Mesophiles grow best between 25- 45 degrees Celsius (Alonzo‚ n.d.). In this experiment both bacteria have grown easily at a maintained room temperature of 26 Celsius. C

ADI Lab Report Every living thing is made up of cells. All cells have some part in common. Some multicellular cells are highly specialized and carry out some very important functions. One of the special cells are red blood cells‚ their functions‚ transporting oxygen from the lungs to the cells in the body. Red blood cells look like little discs. Red blood cells can change their shape‚ this ability allowing them to squeeze through capillaries without breaking. Our task is to Design and carry out an

Introduction and Purpose: This lab focuses on how weight affects the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s) respectively. The primary goal of this lab is to investigate and explain the relationship of these two factors. During the process of conducting this experiment‚ learning to design a lab will also be achieved. Research Question: What is the effect of weight on the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s)? Variable
