What is the more common term for an energy-producing turbomachine? How about an energy-absorbing turbomachine? Explain this terminology, in particular, from which frame of reference are these terms defined-that of the fluid or that of the surroundings?
The common terms for energy producing turbo machine and the energy absorbing turbo machine.
The frame of reference from which these terms are defined.
Explanation of Solution
The most common term used for energy producing turbo machinery is Turbine. Turbine is a mechanical component that extracts kinetic energy from the moving fluid and converts it into the useful mechanical work or energy.
In Frame of reference of fluid, the fluid loses energy to drive the turbine for energy producing devices or turbo machines.
The most common term used for the energy absorbing turbo machines is Pump. Pump is also a mechanical component that absorbs energy from the rotating shaft and uses it to increase the energy of the moving fluid.
In frame of reference of fluid, the fluid gains energy for the energy absorbing devices.
Therefore, the pump absorbs energy from the surroundings and the turbine produces energy from the frame of reference of the surroundings.

- In a stage of Parson's reaction turbine, the mean diameter of the wheel is 1.05 m and the speed is 3000 r.p.m. The angles of receiving tips are 35° and the discharging tips is 20°. If the steam flow rate is 1 kg/min, draw the velocity diagram for blades and evaluate, (a) Tangential thrust on blades (b) Axial thrust on blades (c) Power developed in the blades and (d) Diagram efficiency.arrow_forwardplease wright by hand and steb by stebarrow_forwardIn a trial run, the De Laval steam turbine at Oman Power Plant rotates at 3000 rpm. The steam is issued from the nozzle at 400 m/s and the nozzle angle is 20o. The blade speed ratio is 0.41and the friction loss in the blade channel is 15%of the kinetic energy corresponding to the relative velocity at the inlet to the blades. As a turbine engineer at that station, how do you determine the (i) power developed by the turbine for a flow rate of 10 kg/s and (ii) suitable inlet and outlet angles for the blades when axial thrust is zero. Also, how would you determine the size of the turbine wheel required? Draw a suitable velocity diagram.arrow_forward
