The mass of fuel in a jet must be calculated prior to each flight to ensure that the jet isn’t too heavy to fly. A Boeing 747 is fueled with 24,320 gallons of jet fuel. If the density of the fuel is 0.768 g/cm3 , what is the mass of the fuel in kilograms?

Quantitative: In the 1950s liquid hydrogen was considered as a fuel for a new type of aircraft being developed, the SR-71 Blackbird (shown in Figure 1). Figure 1: The SR-71 Blackbird Early research on the project focused on which fuel to use for the Blackbird. Pratt & Whitney had a J-57 engine that was designed for kerosene and being considered for implementation on the Blackbird. The J-57 only took 5 months to convert to running on liquid hydrogen, however tests...

Norwegian Air Shuttle Aspires to Become the Cheapest Global Airline It’s snowing in Copenhagen as Norwegian Air Shuttle Flight DY7041 lifts off. There are nearly 30 passengers on board, most of them Norwegians, Swedes, and Danes eager to escape the gloom that engulfs their part of the world in late November. Today they will arrive in Florida faster than usual. This is the first direct flight from Scandinavia to Fort Lauderdale. And it’s a bargain: The tickets are a fraction...

The Boeing 747 has a cruising altitude of 45,000 feet and
cruising speed of 275 m/s. At this elevation, the temperature and
pressure according to the US Standard Atmosphere (air properties as
a function of altitude) are 220K and 1.8x104 Pa, respectively. The
engines are steady state devices that can be modeled using the 1st
Law of Thermodynamics with air (ideal gas) as the working fluid
undergoing several processes.
a. The inlet area of the engines is 0.5 m2. What...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
