    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

    ABSTRACT. In this experiment‚ we test factors which affect friction. We pulled a wood block across a surface to determine whetherthe surface area ofthe block orthe type ofsurface affectsfriction. We found that the surface area of the block did not change the coefficient of kinetic friction‚ while the types of materialsin contact were directly related to the coefficient of kinetic friction. INTRODUCTION Friction is a part of our everyday life. Nearly every movement we make involves friction
