A centrifugal air compressor used in a gas turbine receives air at 100 kPa and 300 K and discharges it at 400 kPa and 500 K. The velocity of the compressor's outgoing air is 100 m / s. Ignoring the speed at the compressor inlet. Determine the power required to drive the compressor, in kW, if the mass flow is 15 kg / s. Take the Cp of air equal to 1 kJ / (kg K) and assume that there...

Is this process possible and why?
73 Air at 500 kPa, 980 K enters a turbine operating at steady state and exits at 200 kPa, 680 K. Heat transfer from the turbine occurs at an average outer surface temperature of 320 K at the rate of 40 kJ per kg of air flowing. Kinetic and potential energy effects are negligible. For air as an ideal gas with c, 1.5 kJ/kg K, determine (a) the rate power is developed in kJ...

A combined cycle gas turbine/vapor power plant uses the turbine exhaust as the energy source for the boiler. Each power system uses a single turbine. The gas power system is modeled as an ideal air-standard Brayton cycle. The vapor power system is modeled as an ideal Rankine cycle. Given specific operating conditions determine the temperature and pressure at each state, the rate of heat transfer in the boiler, the power output of each turbine, and the overall efficiency. --Given Values--...

Combustion gases enter an adiabatic gas turbine at 800oC and 900 kPa and leave at 100 kPa with a low velocity. Treating the combustion gases as air (R = 0.2870 kPa*m3/kg, cp = 1.005 kJ/kg*K, k = 1.4) and assuming an isentropic efficiency of 82 percent, determine the work output of the turbine and the exit temperature.

Air modeled as an ideal gas enters a turbine operating at steady state at 1040 K, 278 kPa and exits at 120 kPa. The mass flow rate is 5.5 kg/s, and the power developed is 1200 kW. Stray heat transfer and kinetic and potential energy effects are negligible. Assuming k = 1.4, determine: (a) the temperature of the air at the turbine exit, in K. (b) the percent isentropic turbine efficiency.
