Osborne Reynolds Demonstration Sayed abbas Mohamed 20104762 03 1. Objective: To reproduce the classical experiments conducted by Professor Osborne Reynolds concerning fluid flow condition. 2. Theory: Reynolds number‚ Re is the internationally recognized criterion denoting fluid flow condition. “ Re = 4Q/ πvd ” Osborn Reynolds determined that values of Re could be assigned to define the transition from laminar to turbulent flow. 3. Apparatus: -Osborne Reynolds apparatus

velocity of the flow and g is gravity. Flow Rate The flow rate in a pipe can also be calculated using (eq 2) In this case u is used for velocity‚ Q as volume flow rate and A‚ cross sectional area of the pipe. Reynold’s Number In fluids‚ the Reynolds number (Re) is a dimensionless number which gives a measure of the ratio of inertial forces to viscous forces. The Reynold’s Number is also used to classify laminar and turbulent flow values. When working with pipes that have different

Sacrifices Summary and Characterization The story Sacrifices by R.J Ellory is about Kathleen Reynolds who works as a cop at the Fairfax County Homocide Division. Kathleen Reynolds has given up both husband‚ kids‚ her family and holidays‚ for her career. Later on in the text we are introduced to a woman named Bitsy whose mother is diagnosed with terminal cancer. Bitsy can’t bear seeing her mother in agony‚ and therefore she overdoses the morphine that is used to relieve her mother’s pain‚ with the

smooth pipe shows that there are existence of laminar and transitional flows as stated in Graph 2.0 and Graph 2.1. It is proven that the higher velocity along the smooth bore pipe‚ the higher is the head loss of water. As shown in Table 3.0‚ when the Reynolds’ number increases‚ the value of pipe coefficient friction‚ f decreases along the decreasing stead laminar line. On top of that‚ there are energy loss from the water to the surface of the pipe and therefore‚ the temperature increases when velocity

1. Painters and their craft: Thomas Gainsborough and Joshua Reynolds–their place in the history of English art (genre peculiarities‚ style‚ pictures) Thomas Gainsborough was born in Sudbury‚ Suffolk‚ in 1727. His father was a cloth merchant. Thomas soon evinced a marked inclination for drawing and in 1740 his father John Gainsborough sent him to London to study art. He stayed in London for eight years‚ working under the rococo portrait-engraver Gravelot. He also became familiar with the Flamish

How costly would be for Aer Lingus and Brisith Airways to retaliate against Ryan Air’s launch rather than accommodate it? Currently‚ British Airways and Aer Lingus cannot compete in price at the range that Ryan Air is planning to operate. I believe that British Airways and Aer Lingus would be better off maintaining current prices and differentiating through the service that they offer‚ in the same way that they are. The current cost breakdown offered by the case shows that if British airways

a function of Reynolds number . Theory : The friction resistance to the flow of fluid through a pipe results in a loss of pressure energy for a given fluid flowing a long a given pipe‚ experiments show that for laminar flow : Hl α V And for turbulent flow : Hl α Vn Where : Hl :is the loss of pressure head . V : the mean velocity of flow . n : an index that lies between ( 1.7 – 2.0 ) depending on Reynolds number ( Re ) and on the roughness of the pipe wall. The Reynolds number ( Re )
