GATE ME 2021 : Thermodynamics & Applications Quiz 12 (App update required to attempt this test)

In an axial flow compressor, when the degree of reaction is 50%, it implies that

The maximum blade efficiency of a reaction steam turbine having a nozzle angle of is _________

The pressure ratio of a reciprocating compressor is 8 and having clearance volume as 10% of total volume.If the compression takes place with an index 1.3 and expansion takes place with an index 1.33, then calculate the volumetric efficiency of the reciprocating compressor.

__________%

Steam flows at the rate of 5 at a particular section in a reaction turbine where the diameter of blade is 2m and the velocity of flow is 6m/s. What is the blade height of section _________mm.

In compressor of a Refrigerator, air enters in the axial flow compressor & leaves the compressor axially. Calculate the degree of reaction, if the component of air responsible for whirl is leaving the compressor at one-third the average blade velocity of rotor if the flow velocity at inlet and outlet remain same.
