Liquid Film Motors [pic] Fiona McLaughlin Zoe Cheng Loreto College Coleraine Comments Abstract We have carried out an experimental and theoretical study of liquid film motors. This phenomenon was first reported in 2009. Two papers have been published on arXiv.com‚ the first describing the phenomenon (Shiryaeva et al)‚ the second offering a theoretical model for the observations (Amjadi et al). The

is the basic difference between compressible and incompressible fluid flow? Compressible 1. Fluid velocities are appreciable compared with the velocity of sound 2. Density is not constant 3. Compressibility factor is greater than one. 2. Write the steady flow energy equation for an adiabatic flow of air. In an adiabatic flow q = 0. Therefore energy equation becomes. 2 c12 c2 h1 + + gZ1 = h2 + + gZ 2 + Ws 2 2 Incompressible 1. Fluid velocities are small compared with the velocity of sound 2.

Oil should not be gummy or grayish or smell burnt. • Check automatic transmission fluid‚ should be clear and reddish. • Check the fluid level in the master cylinder as

vaporization or surface tensions are examples of attractive forces. This is the Newton’s law of viscous flow: dfx / dA = η (∂vx /∂z)z Fluids that behave like the equation above are called Newtonian fluids or they go laminar flow. Viscosity coefficient η =kg m-1 s-1 Viscosity measurement is important in many applications. This property of the fluid can be used to determine the rate of mass transport‚ diffusion or within that liquid when it is to be used as a solvent. These are all fundamental

between tissues. With an increase in volume the pressure in the synovial fluids drops forming bubbles. When the joint is stretched far enough the pressure drops so low that these bubbles burst‚ producing a popping sound. It takes half and half for the gas to dissolve back into the synovial fluids. Once gas is dissolved it is possible to pop knuckles again. Synovial fluid present in your joint acts as a lubricant. The fluid contains the gases oxygen‚ nitrogen and carbon dioxide.

• A typical surfer starts at a spot in the water where waves begin to form. They then turn towards the shore. When the surfer sees a wave‚ they paddle towards the beach along with the wave. • When water catches the surfboard‚ the surfer then stands up on the board and soars along the waves crest. • Surfing was discovered first in Hawaii • In 1821‚ surfing was banned by missionaries because they thought it was immoral to surf. • A famous Hawaain swimmer by the name of Duke Kahanamoku Waves
