Problem 2: A home is on fire, and to prevent its spread to the next house, firefighters are spraying down the neighboring house. They reduce their flow rate so that the windows do not break, which would damage the inside of the home. The typical window can withstand a force up to 25 Ibf, what is the largest volumetric flow rate he should allow, given an 8-inch diameter (D1) firehose discharging through a nozzle with 4-inch diameter (d2) outlet. The free jet from the nozzle is deflected by 90° when it hits the window as shown. Window Noale Hose

Engineering Economics Principles

Engineering economics (engineering economy) is a sub-field of economics to study the use and application of the economic principles in the engineering analysis of decisions along with the systematic evaluation of the advantages of project costs inclusive of engineering design and analysis. It emphasizes microeconomics (a subset of economics) for researching the behavior of people in the decision-making process of assigning and determining multiple alternatives to the usage of some of the restrained resources and merging economic theory and engineering practice in a practical manner. It depicts the logical framework of economics in addition to the analytical application of statistics and mathematics.
