Open System Analysis Flashcards
What assumptions are made in the Open System Analysis of a Control Volume
No Accumulation of Fluid
The Energy of the Fluid Stays constant
What are the Equations associated with Volumetric Flow Rate and Mass Flow Rate
(5 Equations total, 1 for volumetric 4 for mass)
Derive the Formula for the Conservation of Energy through a Control Volume
Derive the Formula for the Conservation of Mass through a Control Volume
Simplify the formula for conservation of Energy through a Control Volume
What is a Nozzle and Diffuser
Derive the Conservation of Energy through a Nozzle and Diffuser
Nozzle : Varying Cross-section causing the velocity of a gas to increase
Diffuser: Varying Cross-section causing the velocity of a gas to decrease
What is a Turbine
Derive the Conservation of Energy through a Turbine
A Device which Power is Generated through a gas or liquid passing through a set of blades attached to a shaft
What are Compressors & Pumps
Derive the Conservation of Energy through a Pump
Devices where work is done on the substance , to change their state
Compressor - Substance is a Gas
Pump - Substance is a Liquid
What are Heat Exchangers
Derive the Conservation of Energy through a Heat Exchanger
A Device designed to Transfer heat between two systems
What are Throttling Devices
Derive the Conservation of Energy through a Throttling Device
Device that achieves a reduction in pressure through a restriction , ie partially open valve
What are Boilers and Condensers
Derive the Conservation of Energy through a Boiler & Condenser
Boiler : Converts Liquid water to Steam , at constant temp and pressure when heat is added
Condenser :Converts Steam to Liquid Water, at constant temp and pressure when heat is Extracted
