Brayton cycle question Problem 5 A Brayton cycle operates with a two stage compressor with an intercooler and a two stage turbine with a reheater at an overall pressure ra- tio of 16. The cycle breaths in air from the surroundings at 100kPa and 20°c. Enough heat is added in the combustor so that the maximum temperature of this cycle is 940K. The intercooler reduces the temperature of the working luid to the air inlet temperature, and the reheater raises...
4. A regenerative two-stage gas turbine with reheat operating on the standard-air Brayton cycle is illustrated in Figure 3. In an ideal Brayton cycle, the processes in the turbines and compressor are adiabatic and isentropic, and the air flows through the combustor and heat exchangers at constant pressure. a) Show that the maximum total work output is developed when the pressure ratio is the same across each stage, if the temperature at the inlet to each turbine stage is the...
Thermodynamics 2: STARTING FROM QS 2) 1) In an ideal Brayton cycle air enters the compressor at T = 300K and P = 1 bar with a volumetric flow rate = 20 m3/s. Air enters the turbine at P = 10 bar and T = 1800K. Find: a) The thermal efficiency b) The backwork ratio c) The net power generation in MW 2) For the same states above consider a cycle where the isentropic efficiency of the compressor and turbine...
An ideal Brayton cycle with regeneration is shown below. Note that from 1 to 6, there is a heat rejection process. The pressure ratio is 10 and the inlet to the compressor is at 300 K and 100 kPa. The maximum temperature is 1100 K. Use air as the working fluid, and assume constant properties evaluated at 300 K. (a) Find the net work output and the cycle efficiency assuming the effectiveness of the regenerator is 100% (b) Plot the...
Combined cycle power plants are common because of their high efficiency and scalability. They typically combine a gas turbine cycle (the Brayton Cycle) with a steam turbine cycle (the Rankine Cycle) [1]. The goal of this project is to determine the operating efficiency and profitability of a realistic combined cycle power plant. The power plant is as follows: 1. A natural gas-fired Brayton cycle with mÛ air,Br = 1.25 kg s−1 . (a) Ambient air at 1 bar and 300...
