(d) (4 pts) Identify the limit a compressor approaches i. when the pressure ratio is raised too high at a set mass loading parameter; and ii. when mass loading parameter is raised too high at a set pressure ratio. 01 W1 W2 D .. U = 150 m/s
Draw a compressor map indicating the pressure ratio versus corrected mass flow with rotational speed. On the map, identify the operating points: (a.) design point - high power setting (b.) low power setting (c.) surge line (d.) choke. Also, show these for a degraded condition. Don't forget the Degraded one please
Problem 1 (15 pts) A gas turbine cycle operates with a compressor pressure ratio of 12 and a mass flow rate of 5.0 kg/s. Air enters the compressor at 1 bar, 290 K. The maximum cycle temperature is 1600 K. For the compressor, the isentropic efficiency is 85%, and for the turbine the isentropic efficiency is 90%. Using an air-standard analysis with air as ideal gas with constant specific heats, calculate: a) the volumetric flow rate of air entering the...
6 720 SECTION B- Attempt any TWO Questions from this Section. 4 An air compressor experiences excessive vibrations when running at 1100 rpm. It is fitted with a tuned dynamic absorber in order to reduce these vibrations. The mass of the compressor, me, is 80 kg and the total stiffness of its supports, kc, is 1075 kN/m. The amplitude of the out of balance force, P, is 30 N The compressor with the absorber in place is shown in Figure...

Problem 2/2 (50%) -The gas-turbine cycle of a combined gas-steam power plant has a pressure ratio of 12. Air enters the compressor at 310 K and the turbine at 1400 K. The combustion gases leaving the gas turbine are used to heat the steam at 12.5 MPa to 500 C in a heat exchanger. The combustion gases leave the heat exchanger at 247"C. Steam expands in a high pressure turbine to a pressure of 2.5 MPa and is reheated in...

When released from rest in a uniform electric field of magnitude 1.00 x 10^4 N/C, a charged particle travels 2.00 cm in 2.00 x 10A-7s in the direction of the field. You can ignore any nonelectric forces acting on the particle. Set up your solution to answer the following questions: (i) Is the particle positively or negatively charged? (ii) What is the charge-to-mass ratio of this particle, i.e. the ratio of the charge to the mass? (ii) Other experiments show...
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...
