A marine diesel engine has a compression ratio r = 18 and a cutoff ratio r c
Question:
A marine diesel engine has a compression ratio r = 18 and a cutoff ratio rc = 2.5. The intake air is at p1 =100 kPa and T1 = 300K. Assuming an ideal cold air standard Diesel cycle, what is the engine’s efficiency? Use the ideal and adiabatic gas laws to determine the temperature at points ➁, ➂, and ➃. Compute the work per cycle. What is the power output of this engine if its displacement is 10 L and it runs at 2000 rpm? What is its fuel consumption per hour (assuming the energy content of diesel fuel to be 140MJ/gal)?
Step by Step Answer:
The efficiency can be computed directly from eq 1113 061 Since TV 1 i...View the full answer

An air pump is a device used to inflate or deflate objects by moving air in or out of them. There are many different types of air pumps, ranging from manual hand pumps to electrically powered pumps, and they are used for a variety of purposes. John had trouble blowing up many balloons without a balloon pump and experienced pain. He solved this problem by using an empty plastic bottle with a rectangular-shaped hole in the cap, a cut piece of balloon stretched over it, and a small hole in the bottle. By pressing and releasing the bottle, he created an air pump to inflate the balloons without any discomfort. Air pumps utilize fluid mechanics and thermodynamics principles to increase air pressure inside an object being inflated, such as a bicycle tire. The ideal gas law is used to calculate the pressure inside the tire. As air pressure increases, the object becomes more rigid and can support more weight. The efficiency of the pump is determined by how much of the work done is converted into useful work, such as inflating the tire, and how much is lost as heat. Understanding these principles is important to effectively use and optimize the use of air pumps.
