Difference Betwixt Impulse Turbine In Addition To Reaction Turbine
1. Impulse turbine
2. Reaction turbine
Reaction turbine closed to sum of available release energy is convert into kinetic release energy together with closed to remains inwards line per unit of measurement area energy.
Pressure at inlet of turbine is maximum than the outlet of turbine.
What is departure betwixt Impulse turbine together with Reaction turbine
|Impulse turbine||Reaction turbine|
|1.||Impulse turbine is too called equally velocity turbine||Reaction turbine is too called equally line per unit of measurement area turbine|
|2.||In Impulse turbine all hydraulic release energy kinetic release energy past times nozzle before process.|| Some sum of available release energy is convert into kinetic release energy together with line per unit of measurement area energy|
|3.|| The velocity of jet|
stay atmosphere during process.
|Both line per unit of measurement area together with velocity alter equally fluid move past times through a runner.|
|4.||Pressure is ever atmospheric during process||pressure is alter during process. The inlet line per unit of measurement area of turbine is higher than exhaust|
|5.|| Impulse turbine is|
High caput turbine.i.e depression H2O is required
|Reaction turbine is depression caput turbine.i.e. high H2O is required.|
|6.|| Specific speed of Impulse turbine is|
| specific speed of Impulse turbine is higher range.|
|7.||Water folw is tangential management to the turbine.|| Water menses is radial + axial direction|
to the turbine.
|8.|| Impulse turbine is|
| Reaction turbine is suitable for|
|9.|| Degree of Reaction of Impulse turbine|
| Degree of Reaction of Reaction turbine is greater than zero|
together with less than one
|10.||Velocity tin controlled without loss.||Velocity tin live on controlled simply loss occurs.|
|11.||Impulse turbine is ever installed inwards a higher house tail race together with that turbine non required draft tube|| Reaction turbine by together with large connected to tail race through draft subway which expanding passage.|
This turbine may
Install below or
inwards a higher house tail race.
|12.||Impulse turbine blade is symmetric||Reaction turbine blade are non symmetric.|
|13.||This turbine is required less maintenance||this turbine is required high maintenance.|
|14.||The hydraulic efficiency of Impulse turbine is higher than Reaction turbine.||The hydraulic efficiency of Reaction turbine is lower than Impulse turbine.|
|15.||For same ability evolution the reveal of states required less inwards Impulse turbine|| for same ability evolution the reveal of phase required is higher than Reaction|
|16.||Water tight casing is non required inwards Impulse turbine|| water tight casing is required inwards Reaction turbine because of pressure|
|17.||Impulse turbine is too called equally depression discharge turbine||Reaction turbine is too called equally high discharge turbine.|
|18.||No cavitation employment inwards Impulse turbine.|| High cavitation employment inwards Reaction turbine because|
pressure alter at
Inlet together with outlet.
|19||Relative velocity of fluid is constant inwards Impulse turbine||Relative velocity of fluid inwards increased inwards Reaction turbine.|
|20.|| Fluid non admitted|
to the whole circumference.
|Fluid must live on admitted to the whole circumference.|
|21.||Impulse turbine inlet exclusively kinetic energy||Reaction turbine inlet both kinetic release energy together with line per unit of measurement area energy.|
