A power plant operates one of its steam turbines at a speed of 1800rpm and a steam flow of 139 kg/s with a nozzle velocity coefficient (K) of 0.96. The inlet and outlet steam pressures are 69 bar and 27.6 bar, respectively. Windage and leakage losses are noted to be 3%. The turbine blades are oriented such that the blading angles are13" and 24" with a blade velocity of 70m/s. Using the blade velocity vector diagram (Figure 2), a velocity...

A steam power plant is based on the Rankine cycle with reheat (refer to the figure below). Steam is produced by the boiler/superheater (H-1) at 100 bar and 600 C at a rate of 2.5 kgs. This is expanded to 10 bar in the turbine T-1 and then reheated to 600 °C in heater H-2. The steam is then expanded in turbine T-2 to a pressure of 0.1 bar. The steam is then condensed in condenser (C-1) which operates at...

The figure shows a schematic of a power plant that has two steam turbines. The water (the working fluid for the plant) leaves the high pressure turbine (HPT) as saturated vapour at 1000 [kPa]. Part of this flow is diverted to an insulated heat exchanger, which we hot airstream to create superheated steam that enters the low pressure turbine (LPT). The air mas flow rate is 19.5 k/s and the air temperature drops from 1100 to 6001 as it goes...
