steam jet refrigeration system: - The boiling point of a liquid changes with change in external pressure. In normal conditions‚ pressure exerted on the surface of a liquid is the atmospheric pressure. If this atmospheric pressure is reduced on the surface of a liquid‚ by some means‚ then the liquid will start boiling at lower temperature‚ because of reduced pressure. This basic principal of boiling of liquid at lower temperature by reducing the pressure on its surface is used in steam jet refrigeration

1.0 ABSTRACT The objective for this experiment is to verify the momentum equation experimentally through the impact of jet against deflectors. There are four deflectors used in this experiment. The four deflectors are plate‚ hemisphere‚ slope and cone. The loading weights to be used are 0.8 N‚ 1.0 N‚ 1.5 N and 2.0 N. In this experiment‚ the time taken for the water level in the volumetric tank to raise from 10 to 20 L is determined by using a stop watch. The flow rate‚ calculated force and the error

Southwest Airlines: Using Human Resources for Competitive Advantage Executive Summary Southwest was founded in 1971 with a fleet of three Boeing 737 aircraft. Headquartered at Love Field in Dallas‚ the airline followed a strategy of low fares‚ few frills‚ and excellent customer service. Early on‚ the airline faced many political and regulatory challenges including the Wright Amendment‚ which prohibited the carrier from offering direct service into Love Field from any state other than Texas

IMPACT OF a jet ABSTRACT The objective of this experiment is to determine the force exerted by a jet of water on vanes of various shape.Three different shape of vanes;flat plate‚conical cup‚and hemispherical cup are used for this experiment.The results obtain from the experiment are then used to compare with the theoretical results.Force generated on the surface of vane depends on the rate of change of momentum and it can be calculated by recording the time taken for water to reach a certain

1.0 ABSTRACT The purpose of the impact of jet experiment is to design a system to determine the force generated by the impact of jet on a variety of target vanes. A formula is given to calculate the reaction force at the different vanes caused by the jet. At the end of the experiment‚ the data collected and results calculated will then be compared to theoretical values which are given. Students are expected to be able to come to a conclusion regarding the relationship between the reaction force
