INTRODUCTION The measurement of fluid flow is very important in our daily life from measurements of blood-flow rates in human artery to the measurement of liquid oxygen in a rocket. In this experiment‚ students are to adapt to various ways to measure the flow of essentially incompressible fluids by using the flow measuring apparatus. Students will also be able to understand the application of Bernoulli’s equation in this experiment. The flow is measured by using a venture meter‚ an orifice meter

Different flow rates for water and air is applied to determine the pressure drop and differentiate between the fixed bed and the fluidized bed characteristics. Also the measured onset of fluidization was compared with the predicted one. From this experiment it was obtained thatthe pressure drop increase as increasing the fluid (water or air) rates until it reach constant value. In addition‚ the bed height is constant as flow rate increased in fixed bed and it is increased as the flow rate increased

of the flywheel will increase the energy it stores. Flywheels rotate with a connecting rod; this is known as a shaft. The shaft is where energy moves in and out of the flywheel. This experiment is undertaken to show the actual time measured for a mass‚ connected to a flywheel with a piece of string‚ to travel a distance h is equal to the calculated time of the same height. An example of flywheel applications is the replacement of substations in railway systems with flywheel systems. The number
