What is an indicator diagram in physics?
A curve showing variation of volume of a substance taken along the X-axis and the variation of pressure taken along Y-axis is called an indicator diagram or P-V diagram.
What is area indicator diagram?
4: Indicator diagram. The area which is encircled clockwise represents the positive work produced by combustion. The very narrow area which is encircled counterclockwise represents the work required to pump gases through the cylinder.
What is an indicator diagram what is its importance class 11?
An indicator diagram is basically a chart and could be used to record the pressure in the cylinder versus the volume that is swept by a piston in compressors, etc. This diagram was developed by the Scottish inventor James watt and was used in understanding how the efficiency of steam engines could be improved.
What is an indicator diagram and its use in reciprocating pump?
➢ The indicator diagram for a reciprocating pump is defined as the graph between the pressure head in cylinder and the distance travelled by the piston from inner dead centre for one complete revolution of the crank. ➢ It defines the work done by the reciprocating pump during one complete cycle.
What is an indicator diagram of a thermodynamic process?
A curve showing variation of volume of a substance taken along the X-axis and the variation of pressure taken along Y-axis is called an indicator diagram or P-V diagram. The shape of the indicator diagram shall depend on the nature of the thermodynamic process the system undergoes.
What is the significance of indicator diagram in a thermodynamic cycle?
The indicator diagram is widely used in calculating the work done in the process of expansion or compression. It is found more useful in processes where relationship between P and V is not known. The work done on the system increases its energy and work done by the system reduces it.
Why is priming necessary?
Priming is done to put pump into working order by filling or charging with water. Why Priming is required? Pressure developed by the impeller of centrifugal pump, is proportional to the density of the fluid in the impeller. If the impeller is running in air, it will produce only a negligible pressure.
