A gas turbine has two stages of ideal compression with intercooling in between and two stages of turbine with reheating in between. The air enters the first compressor at 90 kPa and 15°C and the total pressure ratio across each compressor and turbine is 3.5. The total rate of heat addition is 500 kJ/s and the air temperature is increased by 28°C in the regenerator. Calculate the power produced by each turbine, the power consumed by cach compressor, and the rate of heat rejection. Use constant specific heats at room temperature. i) Draw the T-s, diagrams and a schematic of the mechanism, ii) Calculate the power produced by each turbine ii) Determine the power consumed by each compressor

Question

You must solve all questions.

A gas turbine has two stages of ideal compression with intercooling in between and two stages of
turbine with reheating in between. The air enters the first compressor at 90 kPa and 15°C and the
total pressure ratio across each compressor and turbine is 3.5. The total rate of heat addition is
500 kJ/s and the air temperature is increased by 28°C in the regenerator. Calculate the power
produced by each turbine, the power consumed by each compressor, and the rate of heat
rejection. Use constant specific heats at room temperature.

Question 11) Roger gave the following account of a roller-coaster ride: 1 tried a brand-new ride at a science centre. There's a computer screen that tells you how much the car and the people in it weigh and how high and fast you travel. You get into the car and they strap you in. The car weighs 600 kg. At the top, it moves horizontally at a speed of 1 m/s. Then you drop 30 m, make a loop into the air and finish by riding over an 8-m hill. I don't remember our maximum speed or our speed at the top of the loop, but the ride was fantastic!" Answer the following questions without taking the force of friction into consideration. Show your calculations for each question. A v=1 m/s 20 m 8 m a) What is the highest speed Roger could have attained? What is the potential energy of the roller-coaster car when it is at the top of the b) loop? c) What is the kinetic energy of the car as it passes over the top of the 8 m hill? d) What is the total mechanical energy of the system?
