A suburban train has a maximum speed of 70 kmph. The schedule speed including a station stop of 30 seconds is 45 kmph. If the acceleration is 1.5 kmphps, Find the value of retardation when the average distance between stops is 4 km. Discuss the various factors affecting the scheduled speed. 12. Discuss the various methods of lighting calculations. Explain the principle of operation of fluorescent tube. Or An illumination on the working plane of 75 lux is required in room 72m x 15 m in size. The lamps are required to be hung 4 m above the work bench. Assuming a suitable space-height ratio, utilization factor of 0.5, a lamp efficiency of 14 lumens per watt and a candle power depreciation of 20% estimate the number, rating and disposition of lamps.
13. Illustrate the principle of operation of different types of but welding. Or With neat sketch, explain the process of resistance heating. 14. Explain with necessary diagram the construction principle of operation and applications of solar collector. Or Derive the equation for useful energy gain for flat plate solar collector. Explain with neat sketch, solar radiation geometry.
15. Explain how to control the power using aerodynamic. Explain the basic principle of wind energy conversion system with neat sketch. Or Discuss the various types of wind turbine with neat sketch.
Explain how to select the site for the wind energy systems.
