Steady flow process
Fluid flow in which all the conditions at any one point are constant with respect to time
Fluid flow without any change in composition or phase equilibria
Flow velocities do not vary with time
Examples of steady flow process
- groundwater and channel flows
- turbine
- fluid heater
- orifice(throttling)
- nozzle
Non flow process
A thermodynamic process involving no fluid flow
Examples of non-flow process
- Heating at constant volume
- Adiabatic expansion in a cylinder
- Free Expansion (Joules experiment - valve is initially closed and then opened to equalize pressures)
- Heating a fluid in a cylinder at constant pressure

Who has Low flow fire service chimney nozzle?
pok
What are the 2 types of flowchart?
1. High Level Flow Chart 2. Low Level Flow Chart
What is cohesionless granular materials?
Materials which have a low to zero moisture content, where the individual particles do not bond and material will flow at a relatively low angle due to the low particle friction.
What is the importance of chemical engineering thermodynamics for chemical engineer?
Chemical engineering thermodynamics helps a chemical engineer to assess vapour-liquid equilibria of various materials. It helps chemical engineer to evaluate thermodynamic properties and how much heat is evaluated by a particular reaction in a reactor. A chemical engineer will also benefit to operate cryogenic and ultra-low temperature processes by utilizing his skill-set of che engg thermodynamics. It is also helpful if any propulsion mechanism is encountered in any process. The data collected for various parameters such as temperature,pressure, humidity, fugacity, enthalpy etc will help to assign stability and reaction operating conditions as and when required.
Which Materials which offers low resistance to flow of current is a good conductor?
All of them. That's the definition of "conductor".
Types of flow chart?
Flow chart: - A flow chart is a symbolic representation of any process. Each step in the process is represented by a different symbol with a short description of the process. The flow chart symbols are linked together with arrows showing the process flow direction.There ate two types of flow charts1. Low level flow chart2. High level flow chart
What aspect of a substance contributes to a high or low entropy?
thermodynamics
What aspect of a substance contributes to high or a low entropy?
thermodynamics
Why you flow water from water out during distillation process?
To maintain a low temperature, helping the condensation of some components.
What is the difference between the first and secong law of thermodynamics?
The first law of thermodynamic show that heat transfer is equal to work.But he does not give the direction as that system is consuming work or doing work. Whereas the second law of thermodynamic give the direction as (1) Heat can flow naturally from high temperature to low temperature.When heat is flowing from high temperature to low temperature he can produce work.(2)Heat can not flow naturally from low temperature to high temperature.for flowing heat from low temperature to high temperature he consume work. Second law of thermodynamic not only give the direction of heat flow but he also show entropy and quality of energy as high grade energy (mechanical work ) and low grade energy (heat).
What do you consider as low pressure in thermodynamics?
Significantly less that atmospheric pressure, which is 101,300 Pa.
When is a genetic drift a major factor of evolution?
When there is low gene flow.
What are low flow faucet aerators?
Aerators to reduce the flow.
In which direction is heat transferred?
Heat is a form of energy, that energy would flow from a high concentration to a low concentration, i.e. from the warmer system to the cooler system until they reach thermal equilibreum. Research the Zeroth law of thermodynamics
When is genetic drift a major factor in evolution?
When there is low gene flow When there is no selective pressure When there is a bottleneck
Why is water low viscosity?
water has a low viscosity. substitute viscosity for its meaning, resistanse to flow. Water has a low resistance to flow
Do Moen or Kohler make low flow faucets for the bathroom or do they just have showerheads and kitchen faucets that are low flow?
Moen and Kohler both make low flow faucets for the bathroom. They provide them in several styles each.
