Coefficients of Friction Discussion: Friction is the force that resists motion and can be determined in either static situations or kinetic situations using the following equation: [pic] Static friction is the amount of friction that resists the start of motion and kinetic friction resists an object’s continued motion. The coefficient of friction depends on a number of factors including surface area and the types of surfaces in contact. The only way to determine a coefficient of friction is experimentally

flow measuring apparatus is designed to study which the most preferable flow meter from different typical methods of measuring the discharge of an incompressible fluid. This can be identify by measuring the flow rate and the head loss with later to be compared to the different flow meter which is venture meter‚ orifice meter and rotameter. INTRODUCTION The objectives of this experiment are to demonstrate the characteristics of some various commonly used methods of measuring fluid flow rates and to

1. Identify each of the following statements as either true or false. If false‚ explain why. (a) Viscosity is a measure of how easily a fluid flows. (b) Although important‚ fluids are not essential to many living things. (c) A meniscus forms when water particles adhere to the sides of their container. (d) Buoyancy‚ like water pressure‚ acts in all directions. 2. Describe the relationship between mass‚ volume‚ and density of matter. 3. Use the particle theory to explain the differences between

Coefficient of Friction- Post Lab Abstract The purpose of the experiment was to determine to coefficient of friction on a block sliding across a horizontal plane‚ and on the same block sliding down an inclined plane. This was done by first testing block‚ and how much weight on a string was needed to move the block at a constant velocity using a pulley system. The block weighed 0.2385 kilograms‚ and needed a hanging mass of 0.05 kg to move at a constant velocity. This means the coefficient of

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

There are many types of fire-fighting apparatus’ that are in use today and my research is not going to be limited on one particular type of engine but will include a vast majority of engines and their uses. To begin to understand fire apparatus‚ one must define the term engines or apparatus‚ which are what most fire departments‚ call the basic vehicle in this region of the country. But just about anywhere you can find a department where these kinds of apparatus are sometimes referred to as pumpers

EFFECT OF SURFACE AREA ON AIR FRICTION Design Background Information: Air resistance‚ also called drag‚ is the forces that are in opposition to the relative motion of an object through the air. Drag forces act opposite to the oncoming flow velocity. Size and shape are the two factors that affect air resistance. Air resistance depends on the surface area‚ so‚ as the surface area increases‚ the air resistance increases. When an object is falling‚ air resistance acts to push it back up. This is

Abstract The objective of this lab was to determine the relationship (if any)‚ between the pressure and volume of a gas given the temperature and # of molecules remained constant. Using the Boyle’s law apparatus‚ and textbooks to demonstrate pressure it was concluded that there was a relationship between pressure and volume. However‚ the relationship was not a direct relationship‚ and it was determined that the pressure and volume of a gas are inversely proportioned. Thus‚proving Boyle’s theory
