Ratio of chemical A and B in boiler Y is 3 : 2 and Boiler X has ratio of chemical A to chemical B as 1 : 7, 16 litres of mixture is removed transferred from boiler X to boiler Y. What is the total capacity of boiler Y if capacity of boiler X is 144 litres and difference between chemical A and B in boiler Y after transfer is 25 litres? Assume that after transferring 16 litres from boiler X, boiler Y is running at full capacity
Read the passage carefully and choose the best answer to each question out of the four alternatives and click the button corresponding to it. 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?
Read the following statement about boilers. I. Water tube boiler is capable of generating steam of pressure more than 50 kg/cm2 . II. Fire tube boiler is suitable for generating steam of pressure less than 17.5 kg/cm2 . III. Water tube boiler occupy comparatively less space.
Water (CP = 4 kJ/kg K) is fed to a boiler at 30°C, the enthalpy of vaporization at atmospheric pressure in the boiler is 2400 kJ/kg; the steam coming from the boiler is 0.9 dry. What is the net heat supplied in the boiler?
