- what are the instruments/materials used by scientist to study Thermoclines under water.In company that designs road cars and heavy trucks, it important to make the proper selection of the engines. Your part as a system energy engineer is to make a proper selection between an engine operates on Otto cycle/gasoline engine or Diesel cycle/diesel engine. Your head of department asked you to provide a detailed technical report that shows your selection for engine to be used with heavy truck vehicle. This is best achieved by performing the following tasks: Section.1: 1. Which engine does operate at lower rpm and has higher air-fuel mass ratio? 2. Which engine does burn fuel more completely? 3. Which engine has lower fuel cost? 4. Explain what compression ratio for Otto and Diesel cycles means 5. Explain what cut-off ratio for Diesel cycles means 1:06 pm 6. Explain the limitations of SI engines in terms of their ability to operate at much higher compression ratios. What is this limitation called? 7.

- Q4: Describe the suitable major plumbing and firefighting systems for a small residential villa building ?1. a) Write a note on evolution of refrigerants. b) Discuss the modern day refrigerants that are being used by various refrigerator and air-conditioner manufacturers.select if true or false for the following questions 1. For a standard condenser in a refrigeration system, the thermal energy (in J) is equal to the mass (in kg) multiplied by the change in enthalpy across the condenser (in J/kg). 2. Consider a basic refrigeration cycle: Since it requires less work to compress a liquid than a vapor, the entire refrigeration process would work better if the compressor was replaced with a pump. All else being equal, increasing the mass-flow rate of refrigerant will increase the rate of heat transfer at the system’s evaporator. All of these (except, of course, the one labeled, “None of these.”) None of these.

The overflow opening serves two important functions: If the water tap is left on while the drain stopper is closed, the opening will channel water down into the drain opening rather than letting is spill out of the sink onto the floor. The overflow allows the sink to drain faster by introducing air into the system. A sink with a dimension given in Figure Q2(b), has water flows into it at a rate of 8 L/min. If the drain stopper is closed and water level in the sink remains constant, determine the average velocity of water flows through the 3.0 cm diameter overflow hole.
