The first working steam­ powered vehicle was designed and most likely built by Ferdinand Verbies, a Flemish member of a Jesuit mission in China around 1672. It was a 65 cm long scale­ model toy for the Chinese Emperor, that was unable to carry a driver or a passenger. It is not known if Verbiest's model was ever built. Nicolas- Joseph Cugnot is widely credited with building the first full­ scale, self ­propelled mechanical vehicle or automobile in about 1769; he also created a steam­ powered tricycle. He constructed two steam tractors for the French Army, one of which is preserved in the French National Conservatory of Arts and Crafts. His inventions were however handicapped by problems of water supply and maintaining steam pressure. In 1801, Richard Trevithick built and demonstrated his Puffing Devil road locomotive, believed by many to be the first demonstration of a steam ­powered road vehicle. It was unable to maintain sufficient steam pressure for long periods. Sentiment against steam ­powered road vehicles led to the Locomotive Acts of 1865. In 1807 Nicephore Niepce and his brother Claude probably created the world's first internal combustion engine which they called Pyreolophore. The first full­scale, working steam ­powered tricycle was built by:

Consider the following statements for analysis of steam cycles: 1. A steam power plant continuously converts the energy stored in fossil fuels or fissile fuels into shaft work. 2. Steam power plants work on Brayton cycle. 3. In supercritical steam cycle, steam is generated in a 'once-through' boiler at a pressure above the critical point of 27.5 bar. 4. Deaerator is used for the purpose of deaerating the feedwater. Which of the above statements are correct?
In a newly developed innovative idea brought up by CSIR in India, gas turbine exhaust gas are being utilized to convert feedwater into steam. Certain data of the experiment are as follows: mass flow rate of exhaust gas = 40 kg/hr, enthalpy of exhaust gas at the time of their exit from gas turbine is 600 kJ/kg, steam turbine output as measured by brake dynamometer = 60 hp-sec, thermal efficiency of steam power plant is 0.25, efficiency of exhaust gas in converting feedwater into steam is taken as 50%. Find the enthalpy of exhaust gas remaining after they generate steam from feedwater?
Statement I: The condenser in a steam power plant is always filled with a mixture of water, steam and air. Statement II: Slightly wet steam enters the condenser wherein the pressure is below the atmospheric conditions, causing some leakage of air through the glands and also the release of some air dissolved in the boiler feed water.
All power plants use superheated steam due to which of the following advantages? 1. Superheating is mostly done from waste heat of boiler without additional cost of fuel. 2. The plant efficiency increases due to higher temperature of steam. 3. There is less corrosion and erosion of equipment due to absence of moisture in the steam. Select the correct answer using the code given below:
What is the formulae used for calculating the theoretical amount of weight of air required for combustion? kg b) Air required = 100/23 kg c) Air required = 100/23 kg d) Air required = 100/21 kg
