5-1 Chapter 5 MASS AND ENERGY ANALYSIS OF CONTROL VOLUMES Conservation of Mass 5-1C Mass‚ energy‚ momentum‚ and electric charge are conserved‚ and volume and entropy are not conserved during a process. 5-2C Mass flow rate is the amount of mass flowing through a cross-section per unit time whereas the volume flow rate is the amount of volume flowing through a cross-section per unit time. 5-3C The amount of mass or energy entering a control volume does not have to be equal to the amount

conducted in series and parallel to identify the pressure different in both pumps. Centrifugal pump is known as one of the most widely used pumps for transferring liquids. It’s also known as a device to transfer mechanical energy from a prime mover into fluid energy to produce the flow of liquids. The pump is connected in 2 ways; in series and another as parallel pump. Centrifugal pump are connected in parallel because to provide enough flow rates compare to centrifugal pump that connected in series‚ the

Hydraulics – CIVL 2130 Conservation of Energy Aim The aim of this lab experiment is to observe the flow behaviour of water through a pipe of variable section. Firstly‚ we will investigate the interchange of pressure and kinetic energy at each diameter change. Secondly‚ we will study the application of this interchange to the flow metering devices. Lastly‚ energy losses due to friction and pressure effects are estimated. Experimental Apparatus [pic] Pre-lab Question Pressure varies

Use of ScaleSoftPitzer to calculate deposition‚ or precipitation‚ in a reservoir or core material during long term flow. Approach will be presented in four steps: 1. Determine whether equilibrium‚ kinetics‚ or mass transport is controlling‚ 2. Relate precipitation to the physical variables in the field or laboratory core‚ 3. Relate the physical variables that affect scale formation or dissolution to space and time in the reservoir or core material‚ and 4. Combine the two into a single

Hydraulic Jump Experiment SUMMARY The Objective of this experiment is to observe the flow patterns and behaviour of the water before after the jump Also to quantify the energy lost due to a hydraulic jump. The observed and theoretical ratios of upstream and downstream depths will be compared‚ this will show the limitations to purely theoretical analysis. The experiment showed that a hydraulic jump occurs when when liquid at high velocity discharges into a zone of lower velocity

Introduction The water system in any pharmaceutical organization is of vital importance. It is widely used in pharmaceuticals and related industries. Water used in process and in cleaning must be pure and free from microbial and chemical impurities. Laboratories need pure water free of foreign substances‚ which could potentially affect the outcome of analyses‚ and the pharmaceutical industry needs pure water for a variety of purposes – everything from cleaning to the use of pure water as an ingredient
