How much bar needed to convert air to liquid under pressure?
Initially, a minimum of 5.2 bar is needed to convert air to liquid under pressure. This pressure is for the initial process. For the final process, less than 1.7 bar is needed.
What is hyperbolic process in thermodynamic process?
At engineering level technically both process are same except there definition both process give hyperbolic curve in P-V diagram and straight line in T-S diagram. and even in polytropic process PV^n=constant if n=1 then it is not hyperbolic process it is isothermal process even though the definition says pv=c is hyperbolic process.
What is flow and non flow process of first low of thermodynamics?
Steady flow processFluid flow in which all the conditions at any one point are constant with respect to timeFluid flow without any change in composition or phase equilibriaFlow velocities do not vary with timeExamples of steady flow process- groundwater and channel flows- turbine- fluid heater- orifice(throttling)- nozzleNon flow processA thermodynamic process involving no fluid flowExamples 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
What is the equation for isothermal process?
At the boiling point the energy goes into breaking the intermolecular bonds, but the average kinetic energy stays constant and so does the temperature until all of the bonds are broken and the substance is in the vapor state.
Give the initial process statement while system boots up?
System Check _09-) Boot log.
What is isobaric process?
The process in which change in volume and temperature takes place at a constant pressure is called an isobaric process
Is piston cylinder process is constant pressure process or constan volume process?
A piston cylinder process actually includes two processes. The gas inside the piston undergoes both the constant pressure process and the contant volume process.
What is constant in a polytropic process?
In Polytropic process the product of Pressure and Volume (PV) power 'n' is constant where, 'n' is polytropic index
What isothermal process?
Isothermal process is a process in which change in pressure and volume takes place at a constant temperature.
What happens when a gas is compressed keeping the temperature constant?
If pressure is held constant, volume and temperature are directly proportional. That is, as long as pressure is constant, if volume goes up so does temperature, if temperature goes down so does volume. This follows the model V1/T1=V2/T2, with V1 as initial volume, T1 as initial temperature, V2 as final volume, and T2 as final temperature.
What is name of the thermodynamics process if the pressure is constant the volume increases the heat is lost?
isobaric process
Which of the following is true of an isothermal process Temperature is constant W equals Q ΔU equals 0 Pressure is constant?
Temperature is constant.
What is Isochoric process?
Isochoric process is a process in which change in pressure and temperature takes place in such a way that the volume of the system remains constant.
What is isochoric?
Isochoric process is a process in which change in pressure and temperature takes place in such a way that the volume of the system remains constant.
How much bar needed to convert air to liquid under pressure?
Initially, a minimum of 5.2 bar is needed to convert air to liquid under pressure. This pressure is for the initial process. For the final process, less than 1.7 bar is needed.
Why joule Thomson effect is not applicable for hydrogen and hellium?
As the gas flow from high pressure to low pressure using the porous plug the temperature of the gas increases as the pressure of the gas decreases. As we know in all this process the enthalpy is constant. As we know in all this process the enthalpy is constant . So, to stay it constant the internal energy increases which lead to increase in temperature of the gas. Formula h=u+pv h--- enthalpy u-- internal energy p--pressure v---volume
What is the total heat energy supplied in isobaric process?
An isobaric process is one occurring at constant pressure (we are talking about gases). So the specific heat to use is Cp, the specific heat of the gas at constant pressure. To get the total heat energy you obviously need to also know the quantity of the gas involved, and the change in temperature.
