Turbine diffusers are configured to improve pressure recovery within the turbo machinery. The diffuser both converts the non-uniform flow off the impeller into a uniform velocity profile and converts the dynamic energy of the flow into pressure with minimal losses. With an effective diffuser, the rotor exit static pressure will be less than the discharge value which increases the total/static pressure ratio of the turbine. With this increase in total/static pressure ratio, the total to total pressure ratio is reduced, but the overall turbine efficiency is improved..

What are the 4 major section of gasTURBINE engine?
compressor, diffuser, combustion section and turbine
The Mach number at inlet of a gas turbine diffuser is 0.3 The shape of thediffuser would be?
converging
Which part of the centrifugal pump increases the pressure of the liquid?
volute and or diffuser
What turbine does not require draft tube?
Draft tube is used to increase the pressure from the low turbine exit pressure to the pressure of the surrounding to which the fluid is rejected.Only reaction turbines require a draft tube as there is low pressure at the exit of the turbine,where as in an impulse turbine the pressure at the inlet and the exit is essentially the same, which is above the pressure to which the fluid is rejected and thus it require no draft tube.
Why would you not heat the steam coming out of turbine and feedback to turbine?
Steam is redirected back into the boiler from the high-pressure turbine for reheating, but the steam from the low-pressure turbine enters into a condenser to become water again.
What are the 4 main sections of a turbine engine?
compressor section, diffuser section, burner section and turbine
How does pressure recovery occur in a fluid flow system?
Pressure recovery in a fluid flow system occurs when the fluid's kinetic energy is converted back into pressure energy as it slows down and changes direction. This typically happens in areas where the flow expands or contracts, such as in a nozzle or diffuser. The conversion of kinetic energy back into pressure energy helps to increase the pressure of the fluid, leading to pressure recovery in the system.

What is mix pressure turbine?
mix-pressure turbine
What is the wheel chamber pressure in turbine?
Resistance offered by turbine to the steam
What is intermediate pressure turbine?
Some varieties of gas turbine engines (e.g. RR Trent and RB211) have 3 concentric rotating shafts. Each shaft connects a compressor with a turbine. The low pressure compressor, or fan, is driven by the low pressure turbine. The high pressure compressor is driven by the high pressure turbine. Between the low and high pressure compressors there is an intermediate pressure compressor and, guess what... it's driven by the intermediate pressure turbine.
Which part of the centrifugal pump increases the pressure of the liquid?
volute and or diffuser
What is the difference between Diffuser and nozzle?
A nozzle is a device which increases the velocity of fluid by decreasing the Pressure but contrary to it Diffuser is a device that increases the Pressure of fluid at the expense of its velocity

What is throttle pressure regulator of a steam turbine?
Essentially its the pressure prior to entering the turbine chamber via the MSV (main stop valve)
