i need solution in 30 minutes
Q2) A single stage simple impulse turbine generator set is to operate under the following conditions. Steam at inlet :8 bar, dry saturated Exhaust :0.2 bar Nozzle efficiency :0.9 Nozzle angle :15° Internal efficiency :0.75 Mechanical efficiency :0.92 Generator efficiency :0.9 Find (a) the mean blade speed for maximum blading efficiency, (b) the steam flow rate for developing 200 kW.

5.4 The following particulars apply to a two-row velocity compounded impulse stage of a turbine: nozzle angle 17°; blade speed 125 m/s; exit angles of the first row moving blades, the fixed blades, and the second row moving blades, 22, 26, and 30° respectively. Take the blade velocity coefficient for each row of blades as 0.9, and assume that the absolute velocity of the steam leaving the stage is in the axial direction. Draw the velocity diagram for the stage...

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...

1. An industrial plant needs 20,000 lbm of saturated steam at 280°F per hour for heating purposes and ten MW of electrical power. A small turbine system is to be designed to handle both of these needs. Steam is supplied to a turbine at 400 psia pressure from a boiler and expanded until 280°F saturated steam is obtained whereupon the steam needed for heating is extracted. The rest of the steam is expanded in a second turbine to a condenser...

The gas turbine cycle of a gas-steam combined cycle power plant has a pressure ratio of 12. The air enters the compressor at 310 K and 100 kPa (1) and the turbine at 1400 K (3). The combustion gases leaving the gas turbine (4) are used to heat the steam to 12.5 MPa up to 500 °C (6) in a heat exchanger. The flue gas exits the heat exchanger (5) at 247 °C. The steam is expanded in a high...

How do i solve C??? Please details
Steam enters a two stage steady state turbine at 8 MPa and 500 C. It expands in the first stage to a state of 2 MPa and 350°C. Steam is then reheated at constant pressure to a temperature of 500°C before it enters the second stage, where it exits at 30 kPa and a quality of 98%. The net power output of the turbine is 3 MW Assume the surroundings to be at...

A natural gas-fired furnace in a Textile Plant is used to provide steam at 140 0C. At times of high demand, the furnace supplied heat to the steam at rate of 30 MJ/s. The plant also uses up to 6 MW of electrical power purchased from the local power company. The plant management is considering converting the existing process plant into a Cogeneration Plant to meet both their process-heat and power requirements. Your job is to come up with some...
