Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

[4] A multi-storied shopping mall has installed 5 x 110 TR reciprocating compressors of which four compressors are in use and fully loaded for 14 hours per day. The specific power consumption of reciprocating compressor is 0.8 kW/TR. Due to higher energy cost the shopping mall chief engineer has decided to replace reciprocating compressors with screw compressors having specific power consumption of 0.65 kW/TR. The chief engineer needs thefollowing input from energy consultant: • Comparison of power and electricity consumption of both reciprocating and screw compressors?
Your second customer wants to determine the dissipated electrical power by a personal computer, which has a fan that draws 5 L/s of air at 101.325 kPa and 21°C through the box containing the CPU and other components. After that air leaves at 101.325 kPa and 30 °C. Part 1Derive the steady flow energy equation (SFEE) from the first principles. You are required to show all the steps in deriving the SFEE and using both the principles of mass and energy conversation.Part 2Produce specific steady state energy equation (SFEE) by stating all the stated assumption in this equipment in order to be used in later stages without further analysis. Then calculate the pump power.Part 3Apply the short form to determine the dissipated electrical power by the personal computer.
