FLOW MEASUREMENT (Venturi meter‚ Orifice Plate and Rotameter) OBJECTIVES To study the characteristics and applications of various flow measuring device (venturi meter & orifice plate). To calculate the volume flow rate of water from the pressure difference of both venturi and orifice devices. To compare between theoretical and actual volumetric flow rate through the discharge coefficient concept. To know how rotameter works. INTRODUCTION The measurement of fluid flow is important in applications

is random‚ then each time history measurement x(t) of that phenomenon represents a unique set of circumstances which is not Iikely to be repeated in other independent measurements of that same phenomenon. Hence‚ to completely define all properties of the phenomenon‚ it is necessary to conceptually think in terms of all the time history measurements {x(t)} that might have been made. For the usual case of engineering interest where the phenomenon produces continuous time history data‚ an infinite

we measure the mass ‚ the volume of the substance ‚ temperature‚ and pressure. Error This experiment might have errors when the vapor with the flask weighted. The other error would be the temperature that affects the result of the molar mass of the unknown gas. The temperature should be 100 to vapor all the liquid. The last error would be the volume measurement. Wen the volume of the flask is measured the water would be spilled and it will decrease the volume of the unknown liquid‚ in

Objective: The purpose of experiment of density determination is to determine the densities of regularly shaped object and irregular shaped solids as well liquids. Density equal mass over volume. Materials Used: Materials used in this experiment was a regular shaped object and irregular shaped object and a ruler to take the measurements of the object. A graduated cylinder and electric beam balance were used to measure the volumes and masses of the object. As well 5-20% concentrated were

Chapter One: Chemistry and Measurements Describe the “scientific method” in terms of hypothesis‚ experiment‚ theory‚ and law. • The scientific method begins with observation (a woodpecker is make a hole in a tree). • Followed by hypothesis (because the tree has termites) • Followed by experiment (a collection of woodpeckers is observed in a setting in which trees have no termites). • Leading to a refined hypothesis and further experiment to a possible theory (woodpeckers only

Exploring Density Simulation Exploration: Login to the PHET Website. A basic property of any homogeneous substance is its density: the ratio of its mass to its volume. The density of a liquid or solid is an intensive property‚ which means that the density does not vary with the size of the sample but only depends upon its composition. The determination of density is a nondestructive physical process for distinguishing one substance from another. The mathematical relationship is: Density= massvolume
